method for combustion of an oxidant fuel in a heating furnace, and burner for combustion of an oxidant fuel in a heating furnace

摘要

This method relates to a method of combustion of an oxidant fuel in a heating furnace. where fuel and oxidizer are supplied to a burner head. The invention is characterized in that in the first step of the method fuel and oxidant are emitted from the burner head (1; 10) close together so that combustion substantially occurs near and a short distance outside the burner, until a temperature exceeding the spontaneous combustion temperature of the fuel is reached in the burner space; and in that in a second step of the method, fuel and oxidant are emitted, rather than from the burner head (1; 10), at a mutually separate distance, so that combustion occurs essentially at a distance from the head. burner matched on and off the burner.
