InactiveCN113416580AIncrease heightGreat tasteChemical industryCombustible gas productionProcess engineeringEnvironmental geology
The invention provides a fixed bed gasifier, a production system and a production method thereof, and relates to the technical field of coal gas manufacturing equipment. The fixed bed gasifier provided by the invention comprises a furnace body with a feed inlet, a feeding mechanism connected with the furnace body, a fire grate mechanism horizontally and rotatably arranged in the furnace body and a transmission device for driving the fire grate mechanism to rotate. The gasifier has the advantages of efficient and energy-saving structure, convenient transportation and installation, reasonable height-diameter ratio, helps to increase the height of a material layer, not only reduces the sensible heat loss, but also improves the steam taste. The invention further provides a production system which comprises the fixed bed gasifier and other auxiliary purification equipment. The discharge amount of dust, suspended solids and steam in the coal gas is reduced, so that the temperature of a coal gas outlet is very low, and the subsequent coal gas treatment pressure is reduced. The invention also provides a production method for producing coal gas by using the production system, so that the effective gas in the coal gas can reach more than 90%, the steam decomposition rate reaches more than 85%, the residual carbon content is about 2%, and the gasification intensity reaches more than 2000m <3> / m<2>.h.
