In thereactor, at a temperature of about 750 °C and a pressure of about 4 bars, biomass is converted to syngasusing steam. After leaving the gasifier, the heat in the syngas is used to generate steam for the gasificationprocess. After this heat exchange the syngas is cleaned and cooled further down by using a cyclone, adowndraft evaporator, a dust filter and a quench cooler.A part of the generated gas is taken away from the gasifier and passed through in a hot gas dust filter. In ajet compressor this gas flow will be compressed by using generated steam and will be incinerated in acombustion chamber. The flue gas generated by the incineration will be fed into the gasifier and will be usedthere as rotational flow gas, as reactant and as heat supply in the gasification process.In this gasification process, the heat for gasification is generated outside of the gasification reactor and willbe transmitted in an indirect way to the starting material. This generates a syngas with a medium calorificvalue and a relatively high portion of hydrogen of approximately 20%.fluidised bed gasification:Process name:Capacity:FOSTER WHEELERFW CFB Foster Wheeler circulating fluidised bed gasification17 - 60 MW thDescription:atmospheric fluidised bed gasifier• feed biomass with 20 - 60% moisture• pressure atmospheric• temperature 800 - 1000 °C• reactant airStatus:commercialEfficiency: 99.8%page: 130
