2, have the effect that reduces the sulphur content in the flue gas, reduced atmospheric pollution, reach the purpose of environmental protection;
3, burning has reduced air consumption fully.
When single heavy oil composition burnt, the aphlogistic major cause of heavy oil carbon is: fuel spray was not enough; Particle is too big, and the residence time is not enough in the combustion zone.Particle is big more, and is long more in the residence time that combustion zone perfect combustion is required.If its needed burning raid period of time ratio when a little oil rests on burning is also long, then it just can reach the purpose completely of burning.Burn when complete, carbon monoxide is reduced to 0.05, and discharging waste gas reaches environmental requirement.Fuel composition of the present invention is exactly according to this principle, adopts compounding machine to make the catalyzer uniformly dispersing in heavy oil and react, and reaches the purpose of perfect combustion.
1. utilize secondary-atomizing, the principle of microexplosion just, the water that allows coated outside oil touches the high heat of incendiary, allow it vaporize with regard to violent outburst heat at once in the moment of vapour point, be wrapped in the oil of little water particle, just be crashed to pieces littler granule oil immediately, the elaioleucite that diminishes has shortened the required time of perfect combustion.Granule oil diameter is less than 30um, is preferably 0.1-10um, and described nano level composition has best energy-saving effect.
2. described catalyzer is the molecular breakdown of long-chain a short chain, further impels burning fully.
4, reduce fouling, reduction corrosion.Because burning fully, has reduced coking, the carbon distribution of burner hearth; Owing to added basic cpd among the present invention, made a small amount of SO of formation
3Be neutralized, therefore reduced corrosion.
In order to prove above-mentioned effect, the present invention has carried out following test:

Three, experimental period: August 8 July 18 calendar year 2001 to calendar year 2001
Four, experiment place: urea product portion of Ba Ling petro-chemical corporation synthetic ammonia installation one-stage converter.
Five, experimental procedure:
(1) " compound heavy oil " in the burning of one-stage converter 101-B flue, the time be July 18 19:18 to August 8
(2) " compound heavy oil " in the burning at 101-B top, the time is that July 25 was to August 1
(3) burning under " compound heavy oil " different proportioning situations, the time is that August 1 was to August 8
Six, experimental phenomena and result:
(1) main phenomenon
1, during the examination of " compound heavy oil " was burnt, flame was bright, has rigidity, did not have the pipe phenomenon of wafing.
2, July 18 to July 28, all burners do not have coking phenomenon.But after July 28, a little phenomenon of coking appears in furnace roof and flue burner.Test shows: the flue burner was lighted a fire July 18 coking phenomenon was not taken place to July 27, show that the combustion conditions of burner is good before this, but, because it is higher to analyze the compound heavy oil viscosity of discovery from July 26, beginning is added viscosity-depression agent in compound heavy oil, as turps, so also can adjust the burner operating mode, prevent the coking of burner.
3, during the top examination was burnt, the burning quality of flue was good; When oil pressure is higher than 6.5kg/cm
2, atomizing steam is pressed and is higher than 7.0kg/cm
2The time, burner combustion is all right, and can guarantee that pipe row's temperature more than 790 ℃, can reach 800 ℃, and flame quality is better than light oil, as the burning quality of diesel oil; When carrying out the low pressure atomizing, oil pressure is lower than 5.5kg/cm
2, vapour pressure is 3.5kg/cm
2The time, pipe row temperature descends, and when being lower than 780 ℃, flame quality is relatively poor, and no rigidity can't satisfy processing requirement.
4, along with the variation of catalyzer in " compound heavy oil ", the considerable change shown in the following data takes place in the sulphur content in the flue gas.When flue was lighted 3 light oil burners, exhaust gas volumn reduced, and caused sulphur content to reduce.
Analysis of sulfur content data in the flue gas:
A, catalyzer are 20% o'clock, and sulphur content is 50mg/m
3
B, catalyzer are 16% o'clock, and sulphur content is 120mg/m
3
C, catalyzer are 12% o'clock, and sulphur content is 180-240mg/m
3
D, catalyzer are 6% o'clock, and sulphur content is 118mg/m
3
Above-mentioned data are all to burn compound heavy oil flue and furnace roof two and half rows to survey.
E, when burning the single heavy oil heavy oil component and the present composition simultaneously, sulphur content is 180mg/m in the flue gas
3, this moment, the flue burner went out entirely, that is to say that the exhaust gas volumn that heavy oil produces reduces about 60%.When burning the single heavy oil diesel component and the present composition simultaneously, sulphur content is 400mg/m in the flue gas
3, wherein contain the sulphur in the partial fume that the compound heavy oil of flue produces.
F, when only flue burns compound heavy oil, sulphur content is 15mg/m in the flue gas
3
Above-mentioned data are all to burn compound heavy oil flue and furnace roof two and half rows to survey.
Find out that from above-mentioned six groups of data the present invention has when to reduce corrosive effect, especially catalyzer be 20% fuel composition, has good reduction corrosive effect, compares with single heavy oil, effect is more obvious.The single heavy oil if flue burns simultaneously, then the sulphur content in the flue gas will be above 250mg/m
3More than, that is to say that when burning single heavy oil, the sulphur content in the flue gas will be to burn more than 5 times of flue gas sulphur content of compound heavy oil.
5, the variation of catalyzer in " compound heavy oil ", the variation shown in the following data takes place in viscosity.
A, when catalyzer is 18-20%, viscosity is 240 lis of ponds
B, when catalyzer is 12-16%, viscosity is 220 lis of ponds
C, when catalyzer is 6-12%, viscosity is 190 lis of ponds
6, the out temperature of each coil pipe of convection zone and air preheater flue gas is all sent out not changing.
7, the calorific value changing conditions of different ingredients " compound heavy oil " during the furnace roof examination is burnt:
A, when catalyzer is 18-20%, oily cock aperture is 80%, pipe row's temperature is 785 ℃ (the highest 792 ℃)
B, catalyzer are 16% o'clock, oily cock standard-sized sheet, and pipe row temperature is 780 ℃-790 ℃
C, when catalyzer is 6-12%, oily cock standard-sized sheet, and increase 3-6 the burner of exitting of speeding can be kept pipe row temperature more than 780 ℃.
The burning of compound heavy oil in the identical time of d, different proportionings is basic identical, about 1 day burning 6 cars, promptly about 51 tons of compound heavy oil.
8, air consumption obviously reduces.
After " compounded oil " burnt in examination, O in the flue gas
2Content rises to 11.4%, by reducing blower speed, O in the flue gas
2Content maintains more than 4%.Test shows: after compound heavy oil was burnt in examination, blower speed reduced by 50 rev/mins.Because self oxygen part increases in the compound heavy oil, has reduced the air consumption in the combustion processes, therefore, has reduced the rotating speed of gas blower, has further reduced energy consumption.
9, under the certain situation of induced draft fan rotating speed, exhaust gas volumn slightly increases, but changes not obviously, and negative pressure continues to be maintained-2.6～-2.8 * 10P in the burner hearth
a
10, furnace tube outer wall is stained with a small amount of white mass.
11, " compound heavy oil " burning is complete, and CO content in smoke is 0.05%.According to analytical results, the content of CO proves that less than 0.05% compound heavy oil combustion is complete in the flue gas.

Must be from experimental phenomena and table 1 as drawing a conclusion:
1, " compound heavy oil " has burning quality preferably, and flame is bright rigidity, the pipe that do not waft, and burning is complete, and its reason is to make full use of " microexplosion " principle, has reached good atomizing effect.
2, " compound heavy oil " in combustion processes, the air capacity of consumption reduces, its reason is that " compound heavy oil " self oxygen part increases.According to analytical results, after compound heavy oil was burnt in examination, air consumption obviously reduced, and wherein the oxygen level in the flue gas rises to 11.4% by 303%.
3, " compound heavy oil " has the corrosive of reduction function.According to analytical results, catalyst content is 18% when above, SO
2Rise, illustrate that there is reduction corrosive effect in catalyzer.
4, " compound heavy oil " does not influence the thermal equilibrium of 101-B flue firing system, and considerable change does not take place exhaust gas volumn, and its reason is that amount of fuel increases, and air capacity reduces, and keeps balance substantially.Operating mode and relevant processing parameter according to induced draft fan show that burn behind the compound heavy oil, exhaust gas volumn does not have obvious variation.
5, " compound heavy oil " has obvious energy-saving effect, and when the catalyst proportion ratio was 18-20%, energy-saving effect was obvious.During compound heavy oil examination burning, to changing the calorific value certification test of catalytic amount, under the certain situation of the fuel pressure before burner, cock aperture, according to pipe row variation of temperature situation, we draw: catalytic amount is when 18%-20%, and compound heavy oil has remarkable energy saving effect.
The furnace roof burner " compound heavy oil " that is provided according to duration of test urea product portion and the quantity combusted of " single heavy oil " and relevant pipe row temperature, it is as follows that the contriver has carried out the investigation situation to the energy-saving effect of " compound heavy oil ".
A, related experiment data:
Pipe row medial temperature is 782 ℃ during compound heavy oil combustion, and the flat temperature of pipe row is 772 ℃ during single heavy oil combustion; The quantity combusted of the compound heavy oil of each burner is 57.2Kg/hr, and the quantity combusted of single heavy oil is 52.2Kg/hr; If the identical pipe row temperature of control then need increase single heavy oil combustion amount (62.2kg/hr), promptly on the basis of former amount of fuel each single oil-fired burner need to increase amount of fuel be 3.45kg/hr (62.2/18), that is to say that the quantity combusted of single heavy oil under the equal temperature condition should be 56.65kg/hr.
B, analysis on energy saving effect:
Contain 20% catalyzer in " compound heavy oil ", at this moment, the single heavy oil in the compound heavy oil is 80% only, and when that is to say compound heavy oil combustion, the actual single heavy oil consumption amount of each burner is 45.76kg/hr; Nearly weighing oil mass than the single heavy oil combustion time is 10.89kg/hr.That is to say that the heat of 11.44 kilograms of catalyzer releases is equivalent to the calorific value of 10.89 kilograms single heavy oil, therefore, the rate of economizing gasoline that contains " the compound heavy oil " of 20% catalyzer is 17.3%.
C, under the certain situation of oil pressure, atomizing steam pressure, burner, the aperture of the oily cock of burner is represented the quantity combusted of compounded oil, that is to say, reduction with catalyst ratio, the amount of fuel of burner increases, and calorific value reduces simultaneously, must open the off-gas burner and just can keep pipe row temperature.Test shows: compound heavy oil is in examination burning process, and along with the reduction of catalyst ratio, the aperture of oily cock is increased to standard-sized sheet by 80%, simultaneously, when ratio drops to 12% when following, valve wide open can't reach processing requirement, must establish the burner of speeding to exit newly and just can keep pipe row temperature.This is because in the production and utilization of reality, there is the proportioning of optimizing the most in the effect difference that the catalyzer of different proportionings produces in overlapping heavy oil, realizes the purpose of compound heavy oil optimum energy-saving effect.Test shows: compound heavy oil has good joint effect during for 18-20% at catalyst proportion.
By comparing with single heavy oil combustion, single heavy oil is in the incendiary process, be fuel pressure and the flow of guaranteeing the furnace roof burner, must extinguish all flue burners, oil pressure must maintain more than the 0.65Mpa, and the logical oil mass of burner must just can be kept pipe row temperature but also need increase the burner of a little speeding to exit more than 80kg/hr, otherwise pipe row temperature can be reduced to 745-750 ℃.Test shows: under equal processing condition, single heavy oil can't satisfy processing requirement, and compound heavy oil can reach processing requirement, it is more obvious when especially proportioning is 18-20%, this shows heat that compound heavy oil the produces height than single heavy oil in the incendiary process, show that further compound heavy oil has energy-saving effect.
Same oil pump is under the certain condition of oil pump power, because when single heavy oil is burnt in described examination, all flue burners that must go out just can be kept the burning of furnace roof burner, show that the amount that single heavy oil is consumed when keeping same technic index will be higher than compound heavy oil, this shows that also compound heavy oil has energy-saving effect.
This test also provides following detailed testing data: the compound heavy oil consumption data during examination is burnt and the consumption data of single heavy oil component: (described flue has 7 burners to burn compound heavy oil, and 3 burners burn light oil)
A, flue burning: 19 to 25 July, use 234.71 tons in compound heavy oil altogether, wherein flue 6# burner begins the examination burning in 19:18 on the 18th, to flue burner clean burn totally 12 hours (about 1.5 tons) on the 19th, be that 7 days incendiary total amounts of flue burner are 233.21 tons, every day, consumption was about 33.31 tons, and the consumption of each burner is 138.75kg/hr.
B, furnace roof and flue burn simultaneously: July 26 was to July 31, it is 316.88 tons that furnace roof and flue use compound heavy oil amount simultaneously, every day, consumption was 52.813 tons, deduct 33.31 tons of flue consumptions every day, be that furnace roof consumption every day is 19.503 tons, 1.219 tons of each burner of furnace roof every days, the quantity combusted of each burner is 50.789kg/hr.
C, August 1, it was 371.39 tons that furnace roof and flue use oil mass altogether to August 8, and every day, consumption was 46.42 tons, and wherein, flue has only 7 burners to burn compound heavy oil, and flue in addition 3 burners burns single heavy oil, and the consumption of 3 burner every days is 9.99 tons altogether.If the compound heavy oil of flue clean burn, then every day compound heavy oil consumption be 56 tons.
When d, compound heavy oil combustion, there was heavy oil 11.336-11.74m on August 10 in the 9:00 oil tank
3, in the 9:00 oil tanks on the 11st heavy oil 22.715-23.541m is arranged
3, the density of heavy oil is 1005kg/m
3, send heavy oil 4 cars altogether in 24 hours, gross weight is 34.21T.On average per hour consuming the heavy oil amount is 0.931-0.949T, and the consumption of each burner is 0.0517-0.0527T/h.
F, July 20 15:30 to July 23 18:50 consume compound heavy oil 107.9 altogether, experimental session once stopped to burn one hour (because of twice fire extinguishing of motor reason, each treatment time is 20 minutes), 74.5 hours consuming time altogether, the amount of fuel of each burner is 144.83kg/h, wherein between assessment period, the compound heavy oil medial temperature ratio of prescription 1 is high 5 ℃ when burning light oil, and the medial temperature of the compound heavy oil of prescription 2 is than burning 2.5 ℃ of light oil times.
G, heat balance: when producing 1000 tons of ammonia daily, 1 ℃ of prescription 1 the every rising of compound heavy oil, needing heat is 0.07 hundred ten thousand kilocalorie, 1 ℃ of the every rising of compound heavy oil of prescription 2, heat requirement is 0.18 hundred ten thousand kilocalorie.
From above-mentioned four groups of data comparative analyses, as can be known: the consumption of compound heavy oil is a little less than single heavy oil, and wherein the consumption of the compound heavy oil of each furnace roof burner is 50.789kg/hr, and the consumption of single heavy oil is 52.22kg/hr.Be the many 1.5kg/hr of consumption of the compound heavy oil of consumption rate of the single heavy oil of each burner.
2, as can be known, under the control equitemperature condition, the heat that needs to reduce is from above-mentioned " g item ":
5 * 0.07+2.5 * 0.18=0.8 1,000,000 kilocalories/hour, the compound heavy oil amount that promptly need reduce is:
0.8 1,000,000 kilocalories/8.5 hundred ten thousand kilocalories=0.094 ton/hour, promptly should to reduce flow be 9.4 kilograms to each burner.
Therefore the examination value actual this for the 144.83-9.4=135.43 kilogram/hour.
3, from above-mentioned " b item " data analysis with " c item ", the quantity combusted of July 26 to July 31, catalyst ratio was 18-20% compound heavy oil every day is 52.813 tons, the quantity combusted of 8 every day of August 1 to August is 56 tons, that is to say reduction along with compound heavy-oil catalytic agent proportioning, the consumption of the single heavy oil amount in the compound heavy oil increases, about 4.6 tons of single heavy oil increases consumption average every day, about 3.2 tons of the compound heavy oil that increases consumption, consumption calculating with present experiment, every day, the burning ratio be 10% compound heavy oil than ratio was that 20% compound heavy oil the cost that consumes more and is: 4.6 * 1500+3.2 * 1300=11060 unit, if the compound heavy oil of clean burn, should burn 300 tons every day, then every day the burning ratio to be 10% compound heavy oil the cost that consumes than 20% compound heavy oil more is 60,000 yuan, every month consumption increases by 1,800,000 yuan.
Pipe row medial temperature when this test shows compound heavy oil combustion is than high 8-10 ℃ of the pipe row medial temperature of single heavy oil.This be because: under the identical processing condition situation of control, the pipe row medial temperature of burning single heavy oil than the reason of low 8-10 ℃ of the pipe row temperature of compound heavy oil is: compound heavy oil produces higher heat in the combustion processes of reality; The flow of single heavy oil is on the low side, can't satisfy processing requirement.
This test is compared the present invention with burning diesel oil, following detailed testing data is provided again:
1, Dongting Lake nitrogen fertilizer plant synthetic ammonia oil fuel (diesel oil) in 2000 consumption is 318kg/t ammonia.Calendar year 2001, because the 103-JT combustion equipment is transformed, oil fuel consumption reduces 15kg/t ammonia, for guaranteeing the benefit target, the fuel oil consumption index is reduced to 298kg/t ammonia.At present, show that a ton ammonia fuel oil consumption is 220kg according to flow, the theoretical and traditional consumption indicators of substantial deviation, if calculate with 290kg, then current flow demonstration and the relation conefficient between the actual consumption should be 290/220=1.381.
2, by contrast, common property ammonia is 21626 tons during July 18 to August 8 calendar year 2001,4265 tons of the light oil that burns separately consumptions, and 922.98 tons in compound heavy oil, the heavy oil consumption is 786.46 tons in the wherein compound heavy oil.
Test shows: the actual consumption situation analysis of producing for many years from the characteristics and the hole nitrogen of synthetic ammonia installation, ton ammonia diesel consumption can not be lower than 300kg, consider that ullage, storehouse consumption, start-stop car consume, actual consumption should not be lower than 290kg, but data on flows is shown as 220kg, obviously this data substantial deviation actual consumption adopts relation conefficient in the time of therefore can considering to handle these data, reduces error.
Can know from the group data, in the consumption of experimental session light oil is 197.21kg/t ammonia, and the consumption of compound heavy oil is 42.68kg/t ammonia, heavy oil 36.36kg/t ammonia in the compound heavy oil), if adopt relation conefficient to handle, then light oil consumption is: 197.21 * 1.318=259.92kg/t ammonia.
Compare, the calorific value of compound heavy oil is low by 10% than diesel oil approximately by the calorific value calculation of single heavy oil, if be standard with the calorific value:
A, compound heavy oil is converted into diesel oil, experimental session then, the quantity combusted of compound heavy oil is equivalent to: 4268/1.1=38.8kg diesel oil/t ammonia, then: the actual consumption of experimental session oil fuel is about: 259.92+38.8=298.72kg diesel oil/t ammonia;
B, if be converted into diesel oil with single heavy oil, the quantity combusted of heavy oil is equivalent to: 36.36/1.1=33.05kg diesel oil/t ammonia, then the actual consumption of experimental session oil fuel is: 259.92+33.05=292.97kg diesel oil/t ammonia.
After the above-mentioned data processing,, and, also disclosed compound heavy oil simultaneously and had good energy-saving effect a little less than experience or traditional consumption indicators near actual consumption.
6, " compound heavy oil " with the variation of catalytic amount, viscosity changes, catalytic amount increases, viscosity rises, its reason is a polymerization reaction take place, the compound polymerization molecule increases institute extremely.
7, obvious scale formation does not take place in " compound heavy oil " during examination is burnt, and its reason is that burning is complete.System's fouling situation: according to the practical situation of each system's associated temperature, show that system's fouling is not obvious, but from the incendiary practical situation, the transparency of burner hearth height when burning single heavy oil has illustrated that compound heavy oil has the effect that reduces fouling during compound heavy oil combustion.
In the process of compound heavy oil combustion, the burner hearth transparency is higher, and when burning single heavy oil, the transparency in the burner hearth obviously descends.Test shows: owing to increase catalyzer in the compound heavy oil, increased the oxygen part in the compound heavy oil, improved the combustion position of heavy oil, reached the purpose of abundant spray burning, therefore, the transparency of burner hearth is higher.Show also simultaneously that compound heavy oil has the effect that reduces fouling.
During compound heavy oil examination was burnt, a spot of white binding appearred in furnace tube outer wall.Test shows: this phenomenon also occurs in the heavy oil combustion process of Hubei fertilizer plant, these bindings are oxide compounds of the catalyst dust in the heavy oil.
8, " compound heavy oil " has good and economic during for 18-20% at catalyst ratio.Its reason is: a, when proportioning is 18-20%, and catalyzer is given full play to its practical effect, and the single heavy oil amount that is consumed is less, realizes purpose of energy saving.B, catalyzer cost are about 120 yuan/kg, and " compound heavy oil " process cost are about 3 yuan/ton, then " compound heavy oil " cost following (except the water, electricity, gas cost) of different proportionings:
During 18-20%, catalyzer is 1.0kg in " compound heavy oil " per ton, and promptly its cost is 120+3=123 unit/ton;
Catalyzer is 1.2kg in 16% o'clock " compound heavy oil " per ton, and promptly its cost is 120 * 1.2+3=147 unit/ton;
Catalyzer is 1.3kg in 12% o'clock " compound heavy oil " per ton, and promptly its cost is 120 * 1.3+3=159 unit/ton;
Catalyzer is 1.4kg in 9% o'clock " compound heavy oil " per ton; Be that its cost is 120 * 1.4+3=171 unit/ton;
Catalyzer is 1.5kg in 6% o'clock " compound heavy oil " per ton, and promptly its cost is 120 * 1.5+3=183 unit/ton.
In sum, the present invention has the following advantages: the compound combustion composition is complete, and have flame and become clear, the pipe that do not waft, flame has characteristics such as rigidity; Have remarkable energy saving effect, reduced fuel cost; Has the effect of the corrosive of reduction; Fouling is few, and air consumption obviously reduces.
