The assembly includes a preheater and a catalytic recuperative heat generator which contains a suitable oxidation catalyst. An outside air inlet provides communication between the outside air and the heat generator. The assembly also includes a recirculation duct coupled with a fan which form a loop for storing heated oxidized exhaust for later use, and for moderating temperature losses and gains. A return duct also provides heated oxidized exhaust to the preheater. Variable flow control devices are provided at various positions within the apparatus.Field of SearchSolid, extended surface, fluid contact typeElectrical type Including waste gas flow distributor upstream of reaction site and within reaction chamber modifying velocity profile of gas Including solid, extended surface, fluid contact reaction means; e.g., inert Raschig rings, particulate absorbent, particulate or monolithic catalyst, etc. Unitary (i.e., nonparticulate) contact bed (e.g., monolithic catalyst bed, etc.) Superimposed reaction stages in single reaction chamber Reaction stages located within single reaction chamber Electrical type Means injecting internal quench stream into reaction stream downstream of reaction stage And means upstream of extended surface, fluid contact means removing particulate impurities from reactant stream And reactant flow distributor upstream of contact means and within reaction chamber modifying velocity profile of reactant flow | |
