Method and device for the regulated feed of pulverized fuel to an entrained flow gasifier

A method for metering and feeding pulverized fuels under pressure into gasification reactors, comprising:

• supplying the pulverized fuel alternately from an operational bunker through pressurized sluices to a metering tank;
• introducing a fluidizing gas through a turbulence plate into a bottom of the metering tank, to form a dense fluidized bed from the pulverized fuel and fluidizing gas, with transport pipes immersed in the fluidized bed horizontally or vertically, feeding the fuel from the metering tank continuously through the transport pipes via burners to a pressurized gasification reactor or other component;
• and
• feeding in auxiliary gas in an immediate vicinity of a transport line inlet into the metering tank or the transport pipes so that a pressure differential between the metering tank and the gasification reactor or other component is controlled and is utilized as a control parameter for pulverized fuel transport.
