However, any bed exhaust gas will have a certain resistance to consume certain energy when it passes through.

The catalytic combustion incinerator is the same as the convection heat transfer incinerator except that it contains the catalyst in the combustion chamber. Due to the use of a catalyst, it can be operated at lower temperatures, thereby reducing auxiliary fuel consumption and operating costs. The catalyst bed may be a fixed bed or a fluidized bed.

When the fluidized bed catalyst layer is started, the catalyst is in a fluidized state, so that the catalyst has the best contact state with the VOCS. However, any bed exhaust gas will have a certain resistance when it passes through, and it needs to consume a certain amount of energy. Catalysts at high temperatures in the incinerator are sensitive to certain toxic substances. For example, if the lead (Pb) in the VOCS gas to be treated is easily poisoned by the catalyst, some newly generated inorganic salts (such as sodium salt) may also cover the surface of the catalyst. , which leads to a decrease in catalyst activity. For the catalyst covered with inorganic salts, backflushing technology can be used to restore its activity, but only catalysts with very deep poisoning are replaced.

Catalysts such as precious metals have good dispersibility, the concentration at the active site is very low, and the accumulation of precious metal catalysts at high concentration points is also low at high temperatures. If a supported, oxidized metal catalyst is used, its metal oxide crystal structure can be destroyed at high temperatures. Therefore, under high temperature conditions, catalysts such as precious metals should be used.
