Abstract
Gasifier for combusting a particulated carbonaceous fuel by injecting a stream of the fuel into the gasifier combustion chamber together with a combustion supporting gas. The fuel mixture is burned to produce a usable gas and a particulated residual, both of which are directed into a liquid holding quench chamber. A constricted, frusto-conical throat which conducts the usable gas and particulated residual includes one or more nozzles that open into the throat and serve to direct pressurized jets of a scouring fluid into contact with residual particles which have become deposited on the throat wall, to displace the latter and thereby keep the throat void of such deposits.
