A thermochemical conversion of a solid biofuel into a fuel gas is an additional operation prior to application, which can be justified by a more efficient and flexible use of the cleaner gas. The pollution and flue gas cleaning problems from direct combustion of dirty coal are expected to be reduced by more efficient and environmentally con atible integrated gasification combined cycle (IGCC) processes. This strategy for an advanced utilisation of fossil fuels is also suited for solid biofuels like the relatively clean wood, as it is even more suited for the dirtier cereal straw and related herbaceous bio-materials.
