摘要： A furnace exhaust remediation unit comprises an auxiliary combustion chamber with a gas burner assembly optimized for efficient and substantially complete combustion of pollutants, for example, waxy hydrocarbons emitted as binder/lubricant substances are driven off in sintering of green powdered-metal parts. The rate of flow of air and exhaust through the combustion chamber are controlled, permitting control of the average residence time of the emissions, ensuring substantially complete combustion. The burner is arranged such that it provides a high-energy exhaust stream directed tangentially into the combustion chamber, so that a spiral motion is provided to the combustible pollutants, improving mixing and heat transfer and thus ensuring efficient combustion of the vaporized hydrocarbon emissions. The system has a universal modular construction where a burn chamber module; a burn chamber extension module and slide gate damper assembly module are provided. The modular construction permits easy customization of the system to lengthen the burn chamber to increase residence times as well as to facilitate assembly, take-down, cleaning and repair of the system.

摘要： An apparatus and process for treating particulate material within a rotating retort in which gas is injected within the retort to fluidize the particulate material within the rotating retort. An auger is mounted within an axle supporting the retort for rotation and particulate material is injected by the auger within the retort. Gas may be exhausted from the retort through an annular chamber about the auger or from a hollow shaft of the auger. Gas may also be exhausted through a permeable wall of the retort.

摘要： A combustion apparatus comprises a pair or more than two pairs of burner groups. Each burner group comprises one regenerator per a plurality of burners. In each pair of burner groups, a first burner group and a second burner group are fired alternately and waste heat produced when the first burner group is fired is stored in a regenerator of the second burner group. The stored waste heat is utilized to preheat the combustion air of the second burner group when the second burner group is fired. Similarly, waste heat produced when the second burner group is fired is stored in a regenerator of the first burner group, and the stored waste heat is utilized to preheat the combustion air of the first burner group when the first burner group is fired.
