摘要： Switching valve utilizing a rotatable seal suitable for use in a regenerative thermal oxidizer, and oxidizer including the switching valve. The valve of the present invention exhibits excellent sealing characteristics and minimizes wear. The valve has a seal plate that defines two chambers, each chamber being a flow port that leads to one of two regenerative beds of the oxidizer. The valve also includes a switching flow distributor that provides alternate channeling of the inlet or outlet process gas to each half of the seal plate. The valve operates between two modes: a stationary mode and a valve movement mode. In the stationary mode, a tight gas seal is used to minimize or prevent process gas leakage. The gas seal also seals during valve movement.

摘要： An apparatus for treating gaseous pollutants in an air stream such as a regenerative thermal oxidizer or a selective catalytic reduction system, including a reaction chamber wherein the reaction media bed within the chamber comprises a plurality of nonprismatic ceramic blocks each having end faces, side faces and a chamfered face extending at an angle relative to the side faces of the blocks. The ceramic blocks are stacked in end-to-end and side-to-side relation within the reaction chamber and the ceramic blocks each include spaced parallel passages extending through the end and chamfered faces. The chamfered faces of adjacent blocks form voids between the blocks promoting turbulent gas flow through the voids and equalizing the pressure within the reaction chamber. The ceramic blocks may be symmetrical, wherein only a portion of the gas flows into the voids between the blocks and the remainder flows through the channels through the end faces or the ceramic blocks may be nonsymmetrical, wherein the chamfered faces are located vertically opposite an end face, such that all of the gas flowing through the reaction chamber flows through the gas passages into the voids between the blocks at alternative levels.

摘要： The present invention relates to a gas recirculating furnace which aims to enable generation of a high-temperature strong recirculating current and comprises heat sources 3A and 3B for heating a recirculating gas outside the furnace and an out-of-furnace circulating path 4 for taking combustion gas in the inner space of the furnace 18 to the outside of the furnace and flowing it back to the inside of the furnace 18 from a different position. The out-of-furnace circulating path 4 includes: regenerative beds 5A and 5B at recirculating gas current intake and outlet openings 9A and 9B communicating with heating chambers 2; a circulating fan 6; a passage switching device 7 for selectively and alternately connecting an intake side and a discharge side of the circulating fan 6 with one of the regenerative beds 5A and 5B; and a heat removing means 8 for performing heat removal or dilution in order to change gaseity of the gas current in a section between the regenerative beds 5A and 5B, thereby forming inside the furnace 18 a high-temperature strong recirculating current 10 for periodically inverting a flow direction of the gas current by the passage switching device 7.

摘要： A flow of air is provided from a hot air main into a combustion chamber at a time when a burner is firing into the combustion chamber to heat a bed of regenerative media. The flow of air into the combustion chamber helps to keep products of combustion from flowing into the hot air main. In preferred embodiments, sensors sense pressure in the combustion chamber and the hot air main. A controller shifts a valve back and forth within a range of open conditions to regulate the flow of air in response to the sensed pressures.
