Various smoke and combustible gas combustors (200, 300) are disclosed, and also disclosed are systems (100, 200) combining gas combustor with inventive burner. Such a burner (100 or 100') provides combustion of a particulate fuel such as sawdust, and many types of varying moisture content biomass fuels such as poultry litter. The combustors and burners exhibit a high turndown ratio [`TDR"].The smoke or combustible gas combustors (200, 300) are combined synergistically with such a burner (100, 100'), or combined with another suitable burner, so as to provide high temperature burner output gases to the combustor, which has coaxial inner and outer combustion chambers (352, 356) inlet tuyere(s) connected to the inner combustion chamber for introducing combustible smoke or other gases to be burned into the inner combustion chamber at one end thereof with cyclonic flow, and in which combustion air is mixed with combustible smoke or other gases to form a gas stream moving through the inner combustion chamber with cyclonic movement. A preheat tube (331) within the combustible gas heating chamber receives heated exhaust gases from the burner, and communicates with the inner combustion chamber exit through a plurality of apertures (364) for controlled flow of said heated exhaust gases into the gas stream and so heating same by mixing the exhaust gases with the stream of air and combustible gases.

1. A combustible gas combustor for burning smoke and other combustible gases, comprising a combustor housing configured for receiving heating gases from a heat source, the housing defining a refractory-lined or high temperature stainless steel combustible gas heating chamber, a preheat tube located within the combustible gas heating chamber and communicating with a combustion chamber exit for receiving hot combustion source gases, combustible gas tuyeres for introducing combustible gases into the combustible gas heating chamber tangentially to inner walls of the combustible gas heating chamber, such that the combustible gases therein will be heated by the preheat tube, a venturi communicating with the combustible gas heating chamber for creating a partial pressure in the combustible gas heating chamber for drawing gases thereinto, venturi combustion air tuyeres opening though the side walls of the venturi for controllably and forcibly introducing high-velocity combustion air into the venturi and for accelerating flow through the venturi with venturi action, a gas combustion chamber into which the venturi opens in which combustion of the combustible gases occurs, temperature measuring apparatus for measuring temperature in the gas combustion chamber, and a control system for controlling gas and air flows in response to the temperature for controlling combustion of the combustible gases in the gas combustion chamber.
