Abstract
An entrained bed gasifier for operation with particulate or liquid fuels is provided. A reaction chamber defined by a cold screen and a quenching chamber connected to the reaction chamber using a crude gas and slag outlet, wherein at least the cold screen is enclosed by a pressure-resistant pressure mantle. The annular gap between the cold screen and pressure jacket may be filled with a fluid, for example, water or heat transfer oil. A rough pressure equalization between the gasification chamber and the annual gap may be guaranteed using a connection between the annular gap and the quenching chamber or the crude gas line, hence the pressure in the gasification chamber normally remains slightly higher than in the inner water jacket.
