Abstract

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. Combustion products pass cyclonically from the inner chamber and then by reversal of direction, i.e., from downward to upward, through a concentric outer chamber, to create hot products of combustion which exit into the heat exchangers.
