Abstract
The arrangement includes a source of finely divided solid combustible material fluidized in an inert gas, and also a source of combustion-supporting gas, such as oxygen, air, or oxygen-enriched air. A gasifier is provided for gasifying finely divided solid combustible material by reacting the same with combustion-supporting gas, and the gasifier has one or more inlets. A first conduit connects the source of combustible material to an inlet of the gasifier. A second conduit connects the source of combustion-supporting gas to an inlet of the gasifier. A pressure-regulating unit is automatically operative for maintaining the pressure of fluidized combustible material entering the gasifier higher than the pressure of combustion-supporting gas entering the gasifier and higher than the pressure of gases in the gasifier, to prevent the combustion-supporting gas and also the gases in the gasifier from passing out of the gasifier into the first conduit and becoming mixed with fluidized combustible material before such combustible material can enter the gasifier.
