Abstract:
     This invention relates to a kind of fixed-bed highly efficient gasification method for intensifying small granular anthracite and coke, which belongs to the fixed-bed solid-state fuel gasification technical domain. The fixedbed coal gas producer currently employs air blowing flow path, because it is easily to blow the smaller granular fuels out of the furnace, and so it is not suitable for use in the gasification of small granular anthraute and coke. The features of said invention are: to adopt downward air blowing flow path, in order to make the gas producing amount of more than 2mm powdered coal and coke to reach that of big or medium lumped coal or coke, and to raise the all-size coal directly entering furnace rate from the presently about 50% up to around 90%. Said invention is easily and conveniently put into practice with a sizeable benefit, and is very suitable for the technical improvement of employing coal or coke as raw materials in medium or small-sized nitrogen fertilizer..
