Although the fixed bed process its inadequacies and the process is lagging behind compared with other gasification process, but the gasification process is more mature than any other technology. The intermittently Chinas basic national conditions of this design uses atmospheric pressure fixed bed gasification France.This design has the processing of the briquette, briquette binder molding in the molding process of the pulverized coal factors, including the molding pressure, the amount of binder, water content, degree of mixing uniformity, binder type, pulverized coal particle size of pulverized coal forming. System, the mechanism of coal gasification, fuel bed gasification process with air and steam as gasification agent, the chemical balance of the gasification reaction, the reaction kinetics of the gasification process, the manufacturing principles of semi-water gas, gas furnace fuel layer segment conditions and characteristics, details of the mechanism and process of Texaco (UGI) intermittent gasification reaction.This design process calculation on the section of gas, the material balance of the gas stove, proceeds into the furnace of 100 kg fuel out, including ash, dry materials, nonflammable total of 99.99 kg; energy balance, proceedsincluding the fuel calorific value, enthalpy of water vapor in the air, dry air sensible heat, fuel sensible heat total of 2,904,868 kJ out items including blown calorific value with a calorific value objects, blowing the enthalpy of water vapor in the atmosphere, dry blown sensible heata total of 1,575,130 kJ; in the gas phase, respectively, accounting for carbon, hydrogen, oxygen, nitrogen, sulfur; heat balance, the proceeds including the enthalpy of the fuel calorific value, fuel heat, steam and nitrogen in the airthe enthalpy of water vapor, dry nitrogen air sensible heat total of 3,538,661 kJ 4,413,465.74 kJ in the item, and then have the gas efficiency of 80.18%; the equipment calculations the selection 3000mmUGI gas stove, each hourly capacity of 7500 m3 of water gas by the annual production of calculate the required 78 units.Key words：Bri
