Title:
PNEUMATIC BED GASIFIER
Document Type and Number:
Japanese Patent JPH0711263
Kind Code:
A
Abstract:
PURPOSE: To obtain a pneumatic bed gasifier efficiently operable continuously for a long period without sticking molten slag scattered together with a produced gas flowing out of a gasifying part to a heat recovering part.
CONSTITUTION: A nozzle 32 for jetting a cooling gas at a lower temperature than the melting temperature of a fine powdery solid raw material is arranged in an upper part of a gasifying part 26 to reduce the temperature of a molten slag scattered together with the produced gas, weaken a turning stream of the produced gas and prevent the slag from sticking to heat-transfer pipes 44 in a heat recovering part 28. Thereby, the pneumatic bed gasifier can efficiently be operated continuously for a long period.
