The utility model relates to a bulking bed gas generating furnace, the furnace body of which is full water jacket type. The utility model is characterized in that the inner wall of the furnace body is 'U'-shaped; a slant coal feeder, a coal preheater, a secondary gasifier and an air preheater are additionally arranged on the stove body of the prior art; a grate is changed into a scale-shaped tower type grate. Due to the design of the devices, the utility model has the advantages that the activity of coal can be enhanced, and the reaction can be accelerated; fine coal, powder-shaped coal can be gasified by the utility model (particularly the gasification of low grade coal); the coal can be fully reacted; the gasification intensity of the coal is enhanced; the environment is protected, and the labor strength of workers are lightened with the adoption of automatic wet ash removal; the utility model is an ideal gas generating furnace for low grade coal.
