Various smoke and combustible gas combustors ( ) are disclosed, and also disclosed are systems ( ) combining gas combustor with inventive burner. Such a burner ( or ) 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 ( ) are combined synergistically with such a burner ( ), 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 ( ) 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 ( ) 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 ( ) 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.

Various burner configurations for combustion of a particulate fuel such as sawdust, and many types of varying moisture content biomass fuels such as poultry litter. The burners exhibit a high turndown ratio. the burners include a housing defining an upright combustion chamber lined with refractory material and generally circular cross section, a main combustion region within an upper extent the combustion chamber, an initial combustion zone at a lower end of the combustion chamber of reduced-size cross-section compared to the combustion chamber and a transition region increasing in cross-section from the initial combustion zone to the main combustion region. A principal fuel (e. g. , sawdust) is supplied with combustion air to the initial combustion region, and an auxiliary ignition fuel supplies heat to the initial combustion region for igniting the principal fuel. Multiple sets of tuyeres are provided for controllably introducing combustion air tangentially regions of the combustion chamber for contributing to cyclonic combustion flow in such a manner as to increase diameter of combustion upwardly within the combustion chamber.

A combustor system provides high temperature, high-dwell combustion of emission products, as from charcoal kilns, with inner and outer combustion chambers. Multiple inlets receive emission products from multiple heat exchangers omnidirectionally extending for continuous heat exchange connection between the combustor and emission sources. Hot products of combustion are delivered to each heat exchanger, each with multiple ducts in mutual heat exchange relationship including at least a hot products of combustion duct for receiving at the proximal end hot products of combustion from an outlet of the outer chamber, and conveying the hot products of combustion to the distal end at a respective emission source, an emissions inlet duct for receiving emission products at the distal end from the emission source, and a return products of combustion duct for receiving at the distal end the hot products of combustion and returning them to the combustor. The heat exchanger arrangement is such that the hot products of combustion duct and the return products of combustion duct cause heating of the emission products by the heat exchange relationship. A combustion air intake passage provides intake of combustion air for each heat exchanger, which mixes in the combustion chamber with the emission products.
