PROCESS FOR OPERATING A PLANT FOR THE GASIFICATION OF SOLID FUELS

摘要

The plant for the gasification of solid fuels employs gasification burners which have a feed channel for primary oxygen which is coaxial with the burner axis, a surrounding annular channel for fuel feed and an annular channel surrounding the latter for feeding secondary oxygen. The fine dust deposited from the untreated gas is injected into the axis of at least one fuel/reactant jet, introduced from the latter into the primary reaction zone of the gasification reactor and melted in said zone. According to the invention, the apparent density of the deposited fine dust is determined and taken into account in regulating the mass flow of the fine dust fed to the gasification burners, a feed density of the order of magnitude of 60 to 90% of the fine dust apparent density being employed.
