A process for gasifying carbonaceous solids with gaseous, oxygen-containing gasification agents in a fluidized bed gas process in a gasifier, especially in a high temperature Winkler gasifier

摘要

The invention relates to a method for gasifying carbonaceous solids with gaseous, oxygen-containing gasification agents in a fluidized bed process in a gasifier (2), in particular in a high temperature Winkler gasifier (HTW), in which the carbonaceous solids in the reaction chamber (3) of the gasifier (2) are introduced and gasified in a fluidized bed of the gasifier (2), wherein at least a portion of the entrained in the gas produced particulate matter is deposited and returned to the reaction space (3). In order to provide a simple and cost-effective method, the invention proposes that the carbonaceous solids are introduced pneumatically with dense phase conveying (3a) into the reaction chamber (3) of the carburettor (2).
