Thermal oxidizers

Wet Scrubber Lance Environmental Products Grand Rapids, Mich. Lance Environmental Products’ wet scrubber uses no moving parts and utilizes the high effkiency, Venturi-type design. Exhaust air enters the scrubber where the particulate matter is combined for removal with an atomized stream of water. A I-gpm blowdown stream removes the solids to the waste treatment system. The scrubber is constructed of stainless steel, is over 98% efficient, and is ideally suited for handling the exhaust from batch or continuous sludge dryers or any exhaust requiring particulate removal.

Thermal Oxidizers Epcon Industrial Systems Inc. The Woodlands, Texas

Tellkamp Systems Inc.‘s Roxidizer regenerative thermal oxidizer utilizes a unique two-bed design and a patented four-way switching valve to provide high destruction efficiency and low operating costs. When combined with solvent concentration and air volume reduction techniques, the Roxidizer operates virtually fuel free. Roxidizer technology offers an innovative solution to Clean Air Act compliance problems. Skid mounted units are available to handle air flows from 2,000 to 40,000 cfm.

Thermal oxidizers, or fume incinerators, manufactured by Epcon are used to destroy VOCs or hydrocarbons in exhaust streams. The oxidizer consists of a burner, blower, required controls, and heat recovery system. The process mixes flame and waste stream to obtain a uniform temperature for the decomposition of VOCs. Thermal oxidizers can be offered with secondary heat recovery as an additional air-to-air exchanger that delivers hot air, either for process use or for comfort heat in plants.
