In catalytic incineration, there are limitations concerning the effluent streams to be treated. Waste gases with organic compound contents higher than 20% of LEL (lower explosion limit) are not suitable, as the heat content released in the oxidation process increases the catalyst bed temperature above 650 °C.
In the denitration system, as an important high-efficiency heat exchange equipment, GGH can effectively carry out heat recovery, improve the temperature of flue gas entering the denitration reactor, and improve the efficiency of denitration catalyst.
China Special Heat Exchangers Manufacturers, Factory GGH Heat Exchanger for Catalytic Incineration of Vocs Waste Gas Nickel tube lined plastic evaporator as the sea water evaporator with two systems is a high-efficiency anti-corrosion heat exchanger. The main components include a shell, an internally threaded heat exchange tube, a

The Cost Estimation of Thermal and Catalytic Incinerators catalytic incinerator systems. The combustion of dilute concentrations of noxious com- pounds in waste gas streams presents an increasingly rele- vant problem as environmental regulations tighten. Rather than collecting or concentrating these volatile organic com- pounds (VOCs), incineration converts them to
Air preheater is a kind of heat exchange equipment which uses the waste heat of flue gas to heat the air needed for boiler combustion . The air preheater can recover the heat of flue gas
Thermal and Catalytic Incinerators for the Control of VOCsthermal or a catalytic incinerator. In the catalytic incinerator a catalyst is used to increase the rate of the combus-tion reaction, allowing the combustion to occur at lower temperatures. Be-cause the catalytic process operates at a lower temperature than the thermal process, less auxiliary fuel may be re-quired to preheat the waste gas.
Jun 06, 2021 · Zeolite concentration wheel organic waste gas treatment plant molecular sieve rotor \ [email protected] The zeolite runner concentrates the exhaust gas with high air volume and low concentration to the exhaust gas with high concentration and small air volume, thus reducing the input cost and operating cost of the equipment and improving the efficient treatment of voc exhaust gas.
Section 3 VOC Controls(VOCs and others) in the waste gas stream sufficient to raise its own temperature to the desired levels, so that auxiliary fuel (e.g ., natural gas) must be added. The combustion of the waste gases may be accomplished in a thermal incinerator or in a catalytic incinerator. In the catalytic incinerator a catalyst is used to increase the rate of the

Air Pollution Control Technology Fact SheetIn a catalytic incinerator, the gas stream is introduced into a mixing chamber where it is also heated. The waste gas usually passes through a recuperative heat exchanger where it is preheated by post combustion gas. The heated gas then passes through the catalyst bed. Oxygen and VOC migrate to
