Catalyst-oxydative incineration plant
A catalyst-oxydative incineration plant is equipment which serves to clean waste air containing volatile substances. It works on the principle of flameless incineration of poor mixtures on the catalyst. The technology includes a heat exchanger which ensures to maintain an optimal temperature of the catalyst by recuperation of thermal energy originated through burning. The basic performance series of incinerators delivered by the DEKONTA have a capacity ranging from 250 to 5,000 m3 of air per hour. The minimum input concentration may be near to zero, but the operation of the incinerator is economical from the concentration of about 1,000 mg/m3 of organic substances. The maximum input concentration varies according to the kind of combusted substance within the range 8,000 — 15,000 mg/m3.
Properly designed catalytic incinerators have high efficiency, they can process large volumes of highly contaminated air, have low pressure loss and minimal energy demand (at sufficient concentrations of organic substances) and they work in a fully automated regime. One of the minor limitations on the use of catalytic-oxidative incinerators is the presence of catalytic poisons (As, Pb, F, Cl, S, etc.) in clean air. In most cases, it is possible to resolve this problem by selecting a suitable type of catalyst or by pre-treatment of clean air.
