CAS-KR-YL-F type of waste incineration catalyst for digestion to cordierite honeycomb ceramics as the carrier, using the unique high temperature rare earth coating materials, with a high content of noble metal Pd, Pt as active component prepared.Mainly used in waste incinerator, waste carbide furnace installed in field of digestion, digestion furnace exhaust gas treatment system of waste incineration, as a core component of catalytic combustion chamber.
The special catalyst CAS-KR-YL-F can greatly improve the incinerator emissions control level, and then burned in two high temperature flue gas play activity the advantage of processing, the flue gas is fully processing; flue gas emissions far below the national emission standard, the 22mg/m3 CO content in flue gas emissions (150mg/m3), catalytic combustion of flue gas in the chamber two combustion can make full combustion decomposition of dioxin, a flue gas outlet dioxins content is 0.1 ng/m3, lower than the national standard 1 ng/m3; at the same time, the two catalytic combustion reaction heat can be reused.

3.The principle of CAS-KR-YL-F type Waste incineration Digestion catalyst
CAS-KR-YL-F type of waste incineration catalyst as a waste incineration (digestion) furnace core component, usually installed in the garbage incinerator two combustion chamber or digestion furnace exhaust catalytic reaction furnace.
Waste incineration (digestion) furnace is burning (digestion) equipment energy-saving emission reduction of garbage, garbage incineration technology for waste combustion in a furnace inside, a burning (digestion) exhaust after dedusting process into the exhaust gas temperature , into the two catalytic combustion chamber, in the two combustion chamber through the catalyst catalytic oxidation exothermic reaction, temperature of exhaust gas into carbon dioxide and water without pollution, to achieve the elimination of CO and dioxins purposes; the catalytic oxidation burning completely purifying the exhaust waste heat can be used to generate electricity and produce high temperature steam heating, and then through the chimney into the atmosphere.
4.Note of using catalyst
1.The catalyst should be installed using steel seal installation, installation of catalytic bed is divided into 2 sections, channels to align; first section temperature should be controlled below 800 °C.
2.Catalyst prior to use fresh air preheat to 400 °C can pass into the garbage to the top (digestion) of exhaust gas, otherwise easily cause carbon deposition or runaway phenomenon.
3.Low temperature, large amounts of waste incineration (digestion) exhaust in catalytic bed, resulting in "smother", causing temporary catalyst deactivation.
4.Sulphur, phosphorus, arsenic, halogen compounds, heavy metal compounds react with active components of catalyst, resulting in permanent inactivation; should be used in flue gas pretreatment of acidic gases and impurities.
5.Dust, soot, high-boiling viscous material attached to the catalyst surface, covering the catalyst activity, resulting in loss of catalytic role should be used to filter gas pretreatment.
6.The catalytic bed 1 long-term high temperature above 800 °C will make the catalyst carrier and active components of reunion or sintering, resulting in a substantial reduction in the amount of active sites, the final deactivation; catalyst bed 1 should be timely heat
