Description
Technical field
The invention relates to a kind of vapourizing furnace and feed system thereof, refer to especially a kind ofly make mechanism combines to transport fine coal and delivering gas with the charging burner high-temperature gasification stove and feed system thereof through executing of different fire proofed woods.
Background technology
In recent years because the whole world faces environmental protection and energy problem simultaneously, so that national governments and industry member are all paid much attention to the research and development relevant for high energy gamma source efficient and oligosaprobic clean coal technology (clean coal technology).How to promote the service efficiency of coal and reduce the coal pollution for using the primary problem of clean coal technology development at present.In various clean coal technologies; (gasification technique) attracts most attention with gasification technology; Capable of using with various fuel such as coal, refinery coke, give birth to mass-energy and waste etc. as charging; And the synthetic gas of producing (syngas) but diversification use, as producing electric power, be used as fuel and change into chemical etc., so the equal develop actively gasification technology in various countries.
Gasification of coal is meant that coal is in specific equipment; Under certain temperature and pressure; Make organic and oxygenant (like steam/air or oxygen etc.) generation series of chemical in the coal, the solid coal is converted into the process of inflammable gass such as containing CO, H2, CH4 and incombustible gas such as CO2, N2.During gasification of coal, must possess three conditions, i.e. vapourizing furnace, oxygenant and heat supplied, the three is indispensable.The reaction that gasification takes place comprises pyrolysis, gasification and the combustion reactions of coal.The pyrolysis of coal is meant that coal becomes the process of gas, solid, liquid three-phase product from solid phase.Coal gasification and combustion reactions then comprise two kinds of reaction types; Be heterogeneous gas-solid reaction and homogeneous gas-phase reaction; Mainly be two kinds of oxygen and air as for the selection of oxygenant, oxygen will help the lifting of synthetic gas calorific value, but relatively the cost of oxygen generating plant need be provided; Opposite air then need not provide system gas equipment, but the synthetic gas calorific value that is obtained is then relatively low.
Relevant at present vapourizing furnace can roughly be divided into four kinds of patterns; The important consideration parameter of selecting comprises inlet amount, working pressure, service temperature, output synthetic gas composition ... The wherein high-pressure gasified volume that helps saving the design body of heater reduces the utilizations of construction cost and back outlet synthetic gas high-pressure delivery, then depends on the composition ratio of back outlet synthetic gas as for the vapourizing furnace service temperature; Mainly the product by required manufacturing decides the synthetic gas composition; The interior temperature of general stove is between 1000～1500 ℃, and in order to keep the temperature of vapourizing furnace, vapourizing furnace inside is used the refractory mortar (or refractory brick) of three stratotype formulas usually.See also Fig. 7; It is for showing the sectional view of known high-temperature gasification stove; Three layers of refractory mortar have different characteristic and function respectively; The innermost layer refractory mortar is a high-temperature-resistant layer 21, and the characteristic of this high-temperature-resistant layer 21 is the high temperature between about 1600～1700 ℃ for the upper temperature limit that can bear, and can continue to keep the high temperature of vapourizing furnace heart reaction zone 24 to carry out in order to gasification.Outermost layer is a thermal insulation layer 23 with the refractory mortar that gasification furnace wall 25 is connected, and main is to block the material of heat-conduction effect with protection gasification furnace wall 25, and the general permissible temperature upper limit is between 1000～1200 ℃.Refractory mortar as for the middle layer is a thermal insulation layer 22 then, lets the interior high temperature of vapourizing furnace be able to keep, and the upper temperature limit of generally allowing is between 1200～1400 ℃.
Be fuel (fine coal, coal water slurry, refinery coke), oxygen (air) and steam sent in the vapourizing furnace simultaneously as for the 26 main work of charging burner and burn-gasification reaction; It is one of considerable gordian technique in the gasification technology; In order before charging, fuel to be mixed completion in advance with oxygen, the premix charging burner 26 that generally can adopt so-called inside and outside tubular type is as feed system.The outer tube 27 of charging burner 26 is used for delivering gas (being generally oxygen or air); The interior pipe 28 of charging burner 26 is used for transfer the fuel-fine coal; And the fuel-fine coal of the gas of outer tube 27 and interior pipe 28 is after the converging transition 29 of charging burner 26 is pre-mixed, and spirt carries out gasification reaction in vapourizing furnace heart reaction zone 24 again.
Because gasification of coal generally all is under the intense environment of HTHP, to carry out; So must be quite careful in operation, must avoid charging burner 26 exit end occur taking place because of externalities fusing and in generation fuel blockage, and then generation high tempering phenomenon; Possibly have this moment under fuel (coal), oxygenant (oxygen) and three kinds of conditions of hot environment at the same time; Directly carry out combustion reactions, directly corrode the more low temperature resistant thermal insulation layer 22 of charging burner 26 or the refractory mortar of thermal insulation layer 23 through high temperature on every side, because fuel and oxygenant still continue charging in charging burner 26 inside; And furnace temperature does not have considerable change; So quite be difficult for discovering, possibly can't bear high temperature because of gasification furnace wall 25 at last, and cause great danger.So the feed system of known vapourizing furnace still has disappearance and haves much room for improvement.
At present the improvement design of feed system is that for example the Chinese patent notification number the 1st, 407 on the demand of promoting efficiency of combustion mostly, No. 274 with No. the 7th, 021,222, USP notification number.No. the 1st, 407,274, Chinese patent notification number " coal powder direct supplying burner "; It is the improvement that is conceived to shower nozzle and nozzle; Install plate washer additional at exit end, shower nozzle has bluff body or hull, and fine coal is changed in the distribution of outlet; Form favourable stable burning things which may cause a fire disaster, to reach underload and high efficiency burning feature.This piece Chinese patent case and the present invention have an otherness in that mechanism is conceptive; The present invention be directed to the demand of improving safety; And proof is under the improvement of improving safety; Do not have influence on its efficiency of combustion, so design focal point is at whole feed system, the pipe outer tube is carried the particular design high temperature material peripheral with the charging burner of different materials, discharge port end respectively in comprising.
USP notification number the 7th; 021; No. 222 " Coal-burning boiler ' s IgnitionBurner "; It in the freezing air cylinder (cooling air cylinder) of burner port end introducing air and the effect that enlarges passage, promotes the efficient of pulverized coal friring in order to increase the incendiary economic benefit.This piece patent major technique is to promote efficiency of combustion at introducing air.
