To prevent excessive NOX pollution caused by coal combustion in the boiler, denitrification of coal should be carried out . The dinitrification treatment is divided into before combustion denitrification, during combustion denitrification and after combustion denitrification.
The flue gas denitrification technology includes dry method(selective catalytic reduction denitrification of flue gas, selective non-catalytic reduction denitrification) and wet method.
At present the denitrification methods adopted by power plant mainly include selective catalytic reduction method and non-selective catalytic reduction method and combined SNCR/SCR flue gas denitrification technology developed on the basis of the previous two. These three flue gas denitrification technologies have their own advantages and disadvantages.
The plate type denitrification heat exchanger produced by our company is the core equipment in the denitrification process.
