Background technology
One, Coal Gasification Technology developing history
The developing history that the exploitation of Coal Gasification Technology and application have approximately been experienced 200 years.Coal Gasification Technology can be divided into fixed bed, fluidized-bed, air flow bed and melting bed 4 kinds by the way of contact of solid and gas, and wherein melting bed technology does not also have the practical application exploitation.
1. fixed bed.Fixed-bed gasification furnace is the vapourizing furnace of developing the earliest, and lower furnace is a fire grate, in order to support top coal seam.Usually, coal adds from the top of vapourizing furnace, and vaporized chemical (oxygen or air and water vapour) then infeeds the bottom from stove, thereby is countercurrent flow between gas-solid.Characteristics are that the coal treatment capacity of unit volume is little, and difficulty maximizes.At present, the fixed-bed gasification furnace in the running mainly contains two kinds of Lurgi gasifier and BGC-lurgi gasifiers.
2. fluidized-bed.Fluidized-bed gasification furnace is supplied with fine coal on breaker plate, under breaker plate, send into vaporized chemical (oxygen, water vapour), and coal is gasified under suspension.Fluidized-bed gasification furnace can not be used the low coal of ash content melting point, and by-product tar is few, and carbon utilisation rate is low.
3. air flow bed.Airflow bed gasification furnace, fine coal and vaporized chemical (O
2, water vapour) be blown in the stove fast gasification together at a high speed from nozzle.Characteristics are by-product tar not, and it is few to generate in the gas methane content.Entrained flow gasification is the main flow of present Coal Gasification Technology, is representing the developing direction of Coal Gasification Technology from now on.Air flow bed can be divided into wet method charging (coal water slurry) air flow bed and dry feed (coal dust) air flow bed again according to feeding manner.The former is representative with the Texaco gasifier, also has polynary slurry pressurized-gasification furnace, multi-nozzle (four burners) coal water slurry pressurized gasifier of domestic-developed; The latter is representative with the shell vapourizing furnace, also has the space flight stove of GSP stove and domestic-developed, two sections stoves, Tsing-Hua University's stove, four nozzle stem powder coal stoves.
Three kinds of advanced persons' coal gasifying process
China introduces and quilt extensively adopts three kinds of advanced coal gasifying process---Lurgi gasifier, shell vapourizing furnace, Texaco gasifier.1. Lurgi gasifier belongs to a kind of of fixed-bed gasification furnace.Lurgi gasifier is to be designed by German LURGI nineteen thirty-nine, through continuous research improve released the 5th generation the type of furnace, actual achievement is best in various vapourizing furnaces at present.Germany SVZ Schwarze Pumpe company has been applied to this type of furnace commercialization device of various waste gasifications.China just introduced early stage lurgi gasifier that Czech makes and has gone into operation in Yunnan in 20th century sixties.The sky ridge Coal Chemical Industry group company that was constructed and put into operation in 1987 is from the IV type lurgi gasifier of 4 diameter 3800mm of Germany's introduction; Successively adopt coals such as Yangquan coal, Jincheng coal and Western Hills land owned by officials coal to make an experiment; Exploration through more than 10 years; Basically grasped the technology that lurgi gasifier gasification meager lean coal is produced synthetic ammonia, the 5th lurgi gasifier that at present builds up gone into operation, formed the ability of producing 450000 tons of synthetic ammonia per year.Domestic lurgi gasifier has Shanxi Lu Ankuang, Xinjiang Guang Hui and the Datang world etc. in that Yunnan fertilizer plant of PLA, Harbin coal machine factory and Yima, Henan producer gas plant are arranged with producer in the producer that builds.
2. Texaco gasifier belongs to a kind of of wet method feeding gas fluidized bed, and what introduce this technology the earliest is Lunan Chemical Fertilizer Factory, Shandong, goes into operation in 1993.At present; Nearly 30 (cover) devices such as China's existing Shandong southern Shandong, Shanghai coking, Shaanxi Weiheization, Anhui Huaihe Riverization, Nanjing petrochemical industry, Nan Hua company put into operation; Some has had more than 10 year service experience, and operation up to the present is good basically, has shown the advance of coal water slurry gasification technology.But Texaco gasifier is strict to the ature of coal restriction ratio, and sludge forming performance difference and ash content are higher, also exists refractory brick cost height, life-span weak point and coal burner to be prone to problems such as frayed.
3. the shell vapourizing furnace belongs to a kind of of airflow bed gasification furnace, is that present world gasification adopts one of maximum type of furnace.The not only available different types of coal of this type of furnace comprises sub-bituminous coal and brown coal inferior, also can be used for the gasification of biofuel and waste etc.The shell gasifying process began one's study in 1972; Build up pilot plant at Hamburg, Germany in 1978, built up the demonstration unit of coal feeding amount 250～400 ton per days in the U.S. in 1987, built up large-scale IGCC device in Holland in 1996; Vapourizing furnace is the monophyly operation, 2000 tons of day processing coal amounts.Enterprise of family has introduced 16 the type vapourizing furnaces surplus hole, Yueyang nitrogen, Hubei dicyclo and the Liuzhou etc. 10 since successively having in 2006 in China.
