Abstract
An entrained flow coal gasifier wherein a high temperature product gas stream is essentially formed by burning char with air. Additional char, formed by partial gasification of coal, is added immediately thereafter to obtain the gasification reaction. Fresh coal is thereafter supplied in a lower temperature region thereby obtaining the volatile components driven off at a relatively low temperature.
