Abstract
A system for the production of fuel gas from solid biomass fuels and for the combustion of said fuel gas is disclosed which comprises a gasification zone for producing a fuel gas from a solid biomass fuel, said gasification zone being adapted for connection to a solid biomass fuel supply and to a gasification air supply, a predetermined ignition point, a pathway for conveying fuel gas from the gasification zone to the ignition point, and a combustion air injection device for mixing fuel gas and combustion air at the ignition point to initiate combustion of the fuel gas and the combustion air, and for shaping and directing the flame produced, said device being adapted for connection to a combustion air supply. A process for retrofitting a heat transfer device, such as a steam or hot water boiler, a thermal liquid heater, or a kiln, which has a combustion zone and a heat transfer area adjacent to the combustion zone, is also disclosed which comprises providing a gasification zone for producing fuel gas from solid biomass fuel, connecting a solid biomass fuel supply and a gasification air supply to the gasification zone, providing a pathway between the gasification zone and the combustion zone, providing a predetermined ignition point in the pathway, providing a combustion air injection device in the pathway for mixing fuel gas and combustion air at the ignition point to initiate combustion of the fuel gas and the combustion air and for shaping and directing the flame produced into the combustion zone toward the heat transfer area, and connecting a combustion air supply to the combustion air injection device.
