ABSTRACT:
A method and device for metering and feeding pulverized fuels under pressure into gasification reactors, with the pulverized fuel being supplied alternately from an operational bunker through pressurized sluices to a metering tank, in the bottom of which a dense fluidized bed is formed by introducing fluidizing gas through a turbulence plate, with transport pipes immersed in the fluidized bed horizontally or vertically, by which the fluidized fuel is fed continuously through burners to a pressurized gasification reactor. By feeding in auxiliary gas in the immediate vicinity of the transport line inlet into the metering tank or the transport lines, the pressure differential between the metering tank and the gasification reactor is controlled and is utilized as a control parameter for pulverized fuel transport.
