Abstract:
A combustor system for high temperature, high-dwell combustion of emission products by connection to at least one source of emission products, comprising:a combustor defining an internal combustion chamber for combustion of emission products, an inlet for receiving emission products to be combusted in the chamber, and a hot products of combustion outlet for providing outward flow of hot products of combustion from the combustion chamber,at least one of permissible multiple heat exchangers connected to the inlet, the heat exchangers corresponding to each source of such emission products, and extending between the combustor and source of emission products for providing connection between the combustor and each source of emission products, each of the heat exchangers having a proximal end for connection to the combustor and a distal end for connection to a source of emission products,each such heat exchanger comprising 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 the hot products of combustion outlet, and conveying the hot products of combustion to the distal end,an emissions inlet duct for receiving emission products at the distal end from the source of emission products, anda return products of combustion duct for receiving at the distal end the hot products of combustion and returning them to the combustor,such that the hot products of combustion duct and the return products of combustion duct cause heating of the emission products by said heat exchange relationship,a combustion air intake passage for providing intake of combustion air for introduction into the combustion chamber for mixing therein with the emission products provided by the emission products duct to provide mixed combustion products into the combustion chamber for high temperature combustion therein,the combustor being configured for flow of combustion products passing therein to create hot products of combustion,a circulation means to create a partial pressure within the system for causing emission products to be drawn into the emission inlet duct at the distal end from the source of emission products, and for causing drawing into the system combustion air,means for exhausting the return products of combustion after they have flowed through each such heat exchanger.
