摘要

Fluidized bed gasifier consists of a vertical cylindrical tank with plates with alternate peripheral and central overflow for the descending granular charge. The heating medium is passed through straight tubes in an ascending direction through the gasifier. The design is compact and required very little floor space and has a small vol. The heating tubes can be inspected and tested satisfactorily.
