| titleOfInvention | Selective catalytic reduction denitration system |
| abstract | The utility model belongs to a coal fired power plant field, especially a selective catalytic reduction deNOx systems. The method comprises the following steps: a coal-fired boiler: the tail part is provided with a superheater and a reheater; a catalytic reactor: a catalyst layer is arranged inside the catalyst layer; an electric dust removal subsystem; a desulfurization subsystem; a reducing gas injection subsystem: a plurality of nozzles are arranged, wherein one nozzle is arranged near the superheater and the reheater and sprays gas to the positions of the superheater and the reheater; one of the nozzles is arranged near a high-temperature tail flue of the coal-fired boiler and sprays gas to the high-temperature tail flue; a nozzle is also provided adjacent the high temperature back pass adjacent the catalytic reactor to inject reducing gas into the high temperature back pass. The system greatly reduces the content of nitrogen oxides in the flue gas of the thermal power plant by using natural gas, coal bed gas or coal gas through oxidation-reduction reaction, so as to achieve the aim of denitration; the ammonia escape is avoided, the blockage of the air preheater is avoided, and the secondary environmental pollution is avoided. |
