Method for total gasification of wet bituminous fuels

Patent ·
OSTI ID:6741909

This is a discussion of the total gasification of wet bituminous fuels, which comprises heating alternately operated regenerative chambers by burning a portion of recirculated gas, superheating a mixture of recirculated gas and steam in one of the heated regenerative chambers. The heated recirculated gas and steam is then passed upwardly into a gasification zone of a fuel bed and thereby regenerating water gas. A portion of the generated water gas and recirculated gas is then passed through a superposed distillation zone of the fuel bed and thereby distilling gases and vapors from the fuel. Another portion of the generated water gas and recirculated gas in heat exchange with the wet fuel, is passed to a collecting main, recirculating the distillation gases and vapors through the regenerative chamber.
