摘要:
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 (1) via a dense flow conveyor line (51, 52, 53, 54), which is assigned thereto, and with fuel gas via a gas conveyor line (62, 63), 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 (7) for carrying out the method according to the invention.

The invention is directed to a paint box (1) with replaceable color pans (6), having at the bottom of the paint box (1) a holding rail (4) which engages in a downwardly open groove (17) formed on the underside of a protruding rim (15) of the color pans (6), said rail forming a swivel bearing with a swivel axis parallel to the box bottom (2). The groove (17) has a cross section widening in downward direction and the color pans (6) rest loosely on the holding rail (4). Furthermore, on the side of the holding rail (4) close to the color pans (6) provision is made for holding elements (7, 8) extending up from the box bottom (2) and enabling the individual color pans (6) to be securely fixed by frictional engagement with the box bottom (2). Provision is made for a respective push-button (16) on the protruding rim (15) of the color pans (6) on the side of the holding rail (4) remote from the color pans (6). By pressing down the push-button (16) of a color pan (6) this particular color pan is adapted to be swiveled about the swivel axis and disengageable from the holding elements (7 and 8).
