A system is disclosed for converting unconditioned biomass, such as cotton gin trash, into usable energy. This is accomplished by gasifying the biomass, removing the particulate char from the combustible gas using cyclonic separators, burning the gas, and using the heat to generate steam. Two stage combustion helps minimize NOx formation.
