GSi Biomass Gasification Wood and Logs Boiler Pyrolyzer GSi Gasification Boilers:GSi 21kW can trace their DNA fromGSi Biomass Gasification Wood and Logs Boiler Pyrolyzer Central Heating & Hot Water Solid Fuel Boiler. The GSi range of boiler are the latest in technology of extracting heat from renewable sources of energy such as biomass. The process of gasification or pyrolysis involves burning of a combustible matter, carbonizing, without oxygen, this occurs at high temperatures of 500C and above. The produced gases are then ignited in a separate chamber in the
