Formerly the author had introduced some works on The Plant of Pulverized Coal Gasification for synthesis gas, and this time furthermore, discussed some problems about this subject from the view-point of domestic low grade coal utilization.<BR>When compared with Winkler producer, the plant, as studied by Koppers, Co.in Gerniany and U.S.Bureau of Mines, had such advantages as any kinds of coal could be easily gasified, the capacity as large, the construction as simple, the elasticity of capacity was good, and moreover the danger of clinker formation was diminished.<BR>Fine coal employed in the plant contained 75% of powders under 4, 900 mesh.The rate of gasification was 155-200 kg/m3hr.The utility of carbon was 95%.The gas-ification chamber must he constructed almost spherically for efficient- use of radiating heat.As the temperature in the chamber was very high, special attentions must be paled to the selection of fire brick and the heat reCovery, but the higher Construc-tion expenses Could be sufficiently made up by the greater iate of gasification.<BR>The minimum economical unit of this plant was about 10, 000 m3/hr.According to the result of heat balance, the synthetic heat efficiency was 78%, when the sensible heat of produced was recovered by the waste heat boiler.<BR>The outline of the necessary equipments for a 10, 000 m3/hr-plant was described and the constrution expenses and gas production cost were estimated.Finally the author suggested the possibility of cheap synthesis gas production with domestic low grade coals by this plant.
