METHOD AND PLANT FOR USE OF BIOMASS AS SUPPLEMENTARY FIRING IN A GASWORKS

摘要

A method of using biomass as supplementary firing in a combined cycle, combined heat and power plant comprising an internal combustion engine fired with fossil fuel and a steam engine, where steam for the steam engine is generated in a waste heat boiler for the flue gas from the internal combustion engine, and where the biomass is gasified in a gasification reactor to produce a biomass gas, where the biomass gas is carried hot from the gasification reactor and into an afterburner in the waste heat boiler, and combusted there. A combined heat and power plant for carrying out the method is also described.
