The invention relates to a method for starting up a gasifying reactor comprising a plurality of burners. Each burner is thereby charged with combustible dust from a metering vessel () via a dense flow conveyor line (), which is assigned thereto, and with fuel gas via a gas conveyor line (), wherein a fuel mixture of combustible dust and combustible gas is provided prior to a moment of ignition of a burner, wherein a first composition of combustible dust and combustible gas, with which a first burner is charged for ignition, is regulated as a function of the fuel quantity, which was supplied to the second burner for ignition, after the ignition of a second burner, which is charged with a second composition of combustible dust and combustible gas for ignition, following the ignition of the first burner, so that the starting up of each of the plurality of burners of the gasifying reactor takes place under a regulated supply of the fuel load. The invention further relates to a gasifying reactor () for carrying out the method according to the invention.

Method and device for starting up gasifying reactors operated with combustible dust

The invention relates to a device and method for treating a hot gas flow containing slag and to an entrained-bed gasifier system that comprises the device. The device comprises, in a housing, an inlet arranged at the top for the hot gas flow, an immersion pipe, which is arranged vertically and concentrically in the housing and into which the inlet opens, a coolant bath, into which a lower section of the immersion pipe is immersed, and at least one raw gas outlet opening for cooled raw gas that has been freed of slag. The lower section of the immersion pipe is designed as a radially expanded gas distributor bell in the coolant bath. Said gas distributor bell is formed by a substantially conical jacket surface having a cross-section that expands downward, wherein the jacket surface has a plurality of gas passage openings, which are distributed over the circumference of the gas distributor bell. The dimensions of the gas passage openings increase with the immersion depth in the coolant bath.
