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.

[ What is claimed is:] [15.] A process for the production of fuel gas from solid biomass fuels and for the combustion of said fuel gas, said process comprising:(a) gasifying the solid biomass fuel in a gasification zone to produce a fuel gas, said solid biomass fuel being continuously exposed to a supply of gasification air in said gasification zone;(b) conveying the fuel gas from the gasification zone to a predetermined ignition point;(c) mixing the fuel gas with combustion air at the ignition point;(d) igniting the mixture of fuel gas and combustion air to produce a flame; and(e) shaping and directing the flame produced by injecting the combustion air from a plurality of tuyeres which are disposed to cause the combustion air to exit in a swirling pattern such that the swirling air pattern which exits from each tuyere overlaps the swirling air pattern from any adjacent tuyere.
