Abstract
A method for starting high-performance entrained flow gasification reactors with a combination burner or a plurality of pulverized fuel burners, and an ignition and pilot burner. The ignition and pilot burner is ignited, substoichiometrically with fuel gas and a gasifier containing free oxygen. The reactor is brought to the pressure intended and a flow of a fuel gas is supplied with a partial flow of the gasification agent at a substoichiometric ratio through the fuel lines leading to the fuel burner and ignited by the flame of the ignition and pilot burner with a partial flow of the gasification agent. Next, the pulverized fuel is supplied together with a further oxygen-containing gasifying agent through the supply lines to the pulverized fuel burner and is ignited by the flame of the ignition and pilot burner and by the fuel gas flames of the combustible gas generated at the pulverized fuel burner.
