A bio-mass suspension burner for use with furnaces or boilers includes a delivery system for injecting particulate solid fuel into a combustor. A primary air stream mixes with and conducts the fuel into the combustor. Secondary air is introduced at the point of ignition, while tertiary air is introduced tangentially to maintain a cyclonic vortex. The burning, gasified fuel exits the combustor through a nozzle where quartiary air is introduced to burn the gas. Proper flame stability, gasification and ash fusion control is achieved by regulation of the various air streams.
