Boiling Furnace Desulfurization and Denitrification Equipment Product Introduction:

      Desulfurization and denitrification is a process that simultaneously removes SO2 and NOx substances from flue gas. Boilers and kilns require desulfurization and denitrification equipment for flue gas treatment. Industrial boilers include biomass boilers, boiling furnaces, thermal oil boilers, heating furnaces, cracking furnaces, and other industrial boilers. Industrial kilns include rotary kilns, lime kilns, glass kilns, calcining rotary kilns, tunnel kilns, brick and tile kilns, and other industrial kilns.

      The desulfurization processes used in boiling furnace desulfurization and denitrification equipment mainly include dry, wet, and semi-dry methods. The denitrification processes mainly include SCR, SNCR, and PNCR. The specific selection should be based on the properties of the combustion flue gas and the exhaust gas compliance requirements of the environmental impact assessment report. Below is an introduction to the principle of the PNCR denitrification process for boiling furnace flue gas:

      Boiling furnace solid polymer PNCR denitrification process is an in-furnace dry denitrification process. The principle of the PNCR denitrification process is basically similar to the more traditional SNCR denitrification process in China.

      The denitrification agent used in the PNCR process—polymer denitrification agent—is a high-molecular active substance. It is primarily mixed pneumatically and then delivered into the boiler furnace through a spraying device. It is activated and gasified at high temperatures above 700°C, and then instantly undergoes a chemical reaction with the NOx in the flue gas from boiler combustion. Through the reaction, it is reduced to N2 and H2O.
