Description
Technical field
The invention belongs to the glass smelting field, particularly, the present invention relates to be applicable to the solid fuel that dilute phase pneumatic conveying enters glass furnace.In addition, the invention still further relates to above-mentioned solid-fuelled application, preparation method and preparation facilities etc.
Background technology
Directly burning, heating wants efficient much higher with the technology of fusion cast glass than the technology of founding at the glass furnace external heat in glass furnace, can save a large amount of fuel.But directly burning in glass furnace needs to consume a large amount of fossil oils, especially needs low ash, low-sulfur and satisfies the fuel that glass production is not caused other conditions of disadvantageous effect, such as Sweet natural gas and heavy oil etc.
Yet, surging along with oil price, current people are seeking the substitute of the liquid fuels such as heavy oil, comprise Solid-liquid Mixed Fuel and solid fuel.For example, Chinese patent application discloses a kind of Solid-liquid Mixed Fuel for fusion cast glass No. 200610069803, it comprises 5 ~ 80% refinery coke, 20% ~ 95% oil fuel and a small amount of moisture content, emulsifying agent and dispersion agent, but, this propellant combination still needs to consume the more expensive heavy oil of a large amount of prices, and it is fluid form, can't use current strength solid-fuelled device, especially this article to represent that clearly coal dust does not burn owing to the restriction of ash oontent and calorific value is suitable for directly to enter in the glass furnace; And for example, the paper of No. the 02807101st, Chinese patent application and Ceng Xiaojun etc. (petroleum coke powder directly burns at glass melter and replaces the applicability analysis of heavy oil. glass and enamel, 36(3): 23-27) disclose refinery coke with moiety similar to heavy oil (except the sulphur content) and acted as a fuel and apply in the glass smelting, but prompting can not add the solid fuel of the contour the ash content of coal of coal in glass smelting, but ash content there is very high requirement on the contrary, also proposes in addition the sulphur-fixing agents such as inapplicable Wingdale, unslaked lime and come solid sulphur.
The coal of existing bibliographical information and the composite solid fuel of refinery coke substantially all are applied to blast furnace ironmaking, limestone kiln, cement kiln, boiler etc. in ash content and the insensitive Industrial Stoves of sulphur content, as referring to the paper of Ren Huifeng etc. (experimental study of Combustion of Petroleum Coke Mixed with Coal Powder. combustion science and technology, 10(6): 554-558), even there is bibliographical information to come fusion cast glass with coal dust or petroleum coke powder, when but refinery coke is used in prompting, require low sulfur content; When using coal, require low ash content, the use of desulfurization refinery coke and low ash coal will greatly increase raw materials cost.What is more important, above-mentioned all application all are confined to the application of fossil oil, this moves towards exhausted trend without any active effect just fast for all kinds of fossil oils in the whole world, and existing document the application in the solid fuel of glass furnace does not enlighten to some extent to biomass fuel (especially biomass solid fuel).
The inventor is on the basis of the long-term research experience of technology that oneself the dilute phase pneumatic conveying solid fuel is entered the glass furnace burning, through long-term arduous experiment and the fortune composition that some is accidental, found surprisingly the solid fuel by the cost lower (can use commercially available bituminous coal and high sulfur petroleum coke) of some composition of dilute phase pneumatic conveying and proportioning, not only carry stable, even variable grain is big or small, but fuel still is able to Uniform Dispersion, and ash content is little and light because coal dust is dispersed after the fuel combustion of rational proportion, in the combustion processes that continues, can constantly rise, can't affect glass quality, also can not stop up the facilities such as flue of glass furnace; And the inventor also finds, suitably adds the additives such as calcium carbonate, and the fuel of rational proportion not only can not cause the deposition of calcium sulfate, can so that the high performance fuel burning time disperses more evenly, burn more fully, the SO of generation on the contrary
2Evenly diluted and be not easy and contacted with the larger limestone powder of frit and particle in the glass furnace, can from flue gas, be distributed, can not caused the impact on glass quality; In addition, it is alternative to the part of fossil oil that the inventor has carried out the biomass fuel powder, although find that biomass fuel powder calorific value is lower, but its low ash and low-sulfur performance are enough effectively improved the ash content situation of coal dust in the fuel and the high sulfur content situation of refinery coke, and its low heat value and larger particle also can so that high performance fuel more disperse, the sufficient combustion that is of value to fuel is so that the SO that refinery coke produces
2Evenly diluted, from flue gas, distributed, can not caused the impact on glass quality, be applicable to fusion cast glass fully, therefore can be reduced the use of fossil oil, for Sustainable development is contributed.In addition, the inventor also provides above-mentioned solid-fuelled purposes, preparation method and preparation facilities etc.
Summary of the invention
The object of the present invention is to provide a kind of solid fuel, by rational composition and proportioning, can use commercially available bituminous coal and high sulfur petroleum coke as raw material, need not to reduce in advance ash content and sulfur content, thereby greatly reduce raw materials cost, be applicable to dilute phase pneumatic conveying and enter glass furnace with fusion cast glass; And with the biomass solid fuel powder fossil oil is carried out a part and substitute, thereby reduced the use of fossil oil, be that Sustainable development increases power.In addition, the present invention also aims to provide this solid-fuelled purposes, preparation method and preparation facilities etc.
Particularly, in first aspect, the invention provides and be applicable to the solid fuel that dilute phase pneumatic conveying enters glass furnace, it is characterized in that, it comprises coal dust, petroleum coke powder, biomass fuel powder and the fuel dope that mixes, and wherein fuel dope comprises silicon-dioxide and comprises calcium carbonate or calcium oxide.Preferred this solid fuel is comprised of coal dust, petroleum coke powder, biomass fuel powder and fuel dope.
The inventor finds, even the high-ash like this coal of bituminous coal, in solid fuel and add the interval that additive or other fuel composition make it between the powder and strengthen, ash content is difficult for condensing and becomes large, also can be applied to fusion cast glass through rational proportioning blending.In the specific embodiment of the present invention, because bituminous coal also can be implemented in fusion cast glass, therefore those skilled in the art will envision that the also suitable in the present invention enforcements such as hard coal that ash oontent is lower, therefore in this article, coal comprises bituminous coal, hard coal and brown coal.
The inventor finds, though the refinery coke of the such high-sulfur of high sulfur petroleum coke, through rational proportioning blending in solid fuel and add the interval that additive or other fuel composition make it between the powder and strengthen the SO that burning produces
2Evenly diluted and be not easy and contacted with the larger limestone powder of frit and particle in the glass furnace, from flue gas, distributed easily, also can be applied to fusion cast glass.In the specific embodiment of the present invention, because high sulfur petroleum coke can be implemented in fusion cast glass, therefore those skilled in the art will envision that the also suitable in the present invention enforcements such as middle sulphur petroleum Jiao, low-sulfur refinery coke and desulfurization refinery coke that sulphur content is lower, therefore in this article, refinery coke comprises high sulfur petroleum coke, middle sulphur petroleum Jiao, low-sulfur refinery coke and desulfurization refinery coke.
Preferably in the solid fuel of first aspect present invention, the weight proportion of coal dust, petroleum coke powder, biomass fuel powder and fuel dope is 5 ~ 65:30 ~ 65:5 ~ 33:0.5 ~ 5, is preferably 8 ~ 58:33 ~ 61:8 ~ 30:1 ~ 2.For example, in the specific embodiment of the present invention, the weight proportion of coal dust, petroleum coke powder, biomass fuel powder and fuel dope can be 58:33:8:1, or 45:42:11:2, or 30:51:18:1, or 25:57:16:2, or 8:61:30:1, etc.In addition, also preferred in 100 parts of solid fuels, the content of coal dust is 5 ~ 65 parts in the solid fuel of first aspect present invention, and the content of petroleum coke powder is 30 ~ 65 parts, and the content of biomass fuel powder is 5 ~ 33 parts, and the content of fuel dope is 0.5 ~ 5 part; More preferably in 100 parts of solid fuels, the content of coal dust is 8 ~ 58 parts, and the content of petroleum coke powder is 33 ~ 61 parts, and the content of biomass fuel powder is 8 ~ 30 parts, and 1 ~ 2 part of the content of fuel dope.In this article, as do not particularly point out, according to those skilled in the art's general understanding, all proportionings are weight ratio, and umber is weight part.
Preferably in the solid fuel of first aspect present invention, fuel dope is comprised of the raw material powder that is rich in silicon-dioxide and the raw material powder that is rich in calcium carbonate or calcium oxide, more preferably is comprised of limestone powder and sand.Be rich in the raw material powder of silicon-dioxide the most cheap be husky, comprise river sand, sea sand and the artificial sand of pulverizing.Although can adopt, the raw material of silicon-dioxide is rich in the conducts such as the quartz of preferred costliness, mica.The raw material that is rich in calcium carbonate or calcium oxide also is that those skilled in the art know, for example Wingdale and unslaked lime.Although can adopt, the raw material of calcium carbonate or calcium oxide is rich in the not preferred expensive conducts such as marble.In preferred fuel dope, limestone powder and husky weight proportion are 0.5 ~ 3:7 ~ 10, are preferably 1 ~ 2:8 ~ 9.Because in actual use, contain sand and the mineral calcium of higher proportion in the low-quality coal of part, therefore can in solid fuel, additionally not add fuel dope.So the present invention can be equal to the solid fuel that does not contain fuel dope.But preferred, in the specific embodiment of the present invention, limestone powder and husky weight proportion can be 1:9, or 2:8, etc.In addition, also preferably in 10 portions of fuel dopes, the content of limestone powder is 0.5 ~ 3 part, and husky content is 7 ~ 10 parts.
In this article, term " powder " has implication well-known to those skilled in the art, refers to the solids of powdery.The inventor adopts solids to prepare (comprising fuel and additive) solid fuel of first aspect present invention fully, does not use liquid fuel and additive, thereby is implemented dilute phase pneumatic conveying fully, and need not to worry that the situation of solid-liquid separation occurs.The size of powder usually can with can distinguish by the size of sieve aperture, this can grind and the sieve aperture of the corresponding size of jetting is realized by coal pulverizer, the maximum particle diameter of powder is less than screen-aperture, therefore in this article, can distinguish different powder by certain screen-aperture with the powder that coal pulverizer grinds.Because the screen cloth specification in country variant, different industries has different standards, therefore the implication of " order " also is difficult to unification, for this reason, in this article, adopts the order number of sieve as shown in the table and the conversion relation of the grain diameter that can pass through:
Preferably in the solid fuel of first aspect present invention, the maximum particle diameter of coal dust is less than the maximum particle diameter of petroleum coke powder.The inventor finds, in the winding-up tank in dilute-phase pneumatic conveying device, usually the particle diameter of powder does not affect the even of mixing, yet in long transmission pipeline, different-grain diameter, different types of powder have different transmission speeds, even difference is very little, but because the length of transmission pipeline is longer, can cause finally that heterogeneity proportion changes in the solid fuel when being conveyed into glass furnace, causing the unstable of course of conveying and final glass production quality.Therefore, the inventor is through arduous experiment, and the maximum particle diameter of finding coal dust can be eliminated the impact of transmission speed less than the maximum particle diameter 10 ~ 20% of petroleum coke powder the time substantially.Although the paper of Ren Huifeng etc. (experimental study of Combustion of Petroleum Coke Mixed with Coal Powder. combustion science and technology, 10(6): 554-558) instruction can mix and grinds coal and refinery coke, but the inventor adopts and grinds respectively, cross the mode that different sieve apertures separate, solve the unsettled situation that the dilute phase pneumatic conveying composite solid fuel occurs.Therefore, more preferably in the solid fuel of first aspect present invention, the maximum particle diameter of coal dust is less than the maximum particle diameter 10 ~ 20% of petroleum coke powder, and preferred coal dust is the coal dust that can pass through 140 mesh sieves, and preferred petroleum coke powder is can be by the petroleum coke powder of 120 mesh sieves.In the specific embodiment of the present invention, coal dust is the coal dust that can pass through 170 mesh sieves, and petroleum coke powder is can be by the petroleum coke powder of 140 mesh sieves.

Preferably in the solid fuel of first aspect present invention, limestone powder is can be by the limestone powder of 40 mesh sieves.The inventor finds, because the content of limestone powder in solid fuel seldom, owing to collision effect obvious depositional phenomenon can not occur in the dilute phase pneumatic conveying process, and after being conveyed into glass furnace, suitable fast deposition also helps it and breaks away from SO
2Gas reduces the generation of calcium sulfate to the impact of glass quality, can be less on the impact of glass quality than the limestone powder that grinds carefullyyer on the contrary by the limestone powder of 40 mesh sieves.In addition, because husky content is larger, therefore for the consideration of dilute phase pneumatic conveying stability, preferably in the solid fuel of first aspect present invention, sand is can be by the sand of 50 mesh sieves, one or more mixtures of No. six sand (50-70 order), No. seven sand (70-100 order) and No. eight sand (100-160 order) preferably, these sand can grind voluntarily, but preferably by buying on the market.
