Chain Grate Boiler PNCR Denitrification Integrated Equipment

      Biomass chain grate boilers are widely used in industrial production. The combustion of biomass fuels produces flue gas containing SOX, NOX, and dust. NOX emissions are one of the main pollutants causing atmospheric pollution. Currently, the common denitrification processes for NOX control include SCR, SNCR, and PNCR. Among them, PNCR was developed based on the properties and characteristics of boiler flue gas. Below is an introduction to the process principles and features of the chain grate boiler PNCR denitrification integrated equipment:

      Chain Grate Boiler PNCR Denitrification Process Principle:

       The PNCR denitrification equipment is an integrated flue gas denitrification device. Its principle primarily relies on polymer denitrification agents. This denitrification agent is a type of high-molecular active substance. Through pneumatic conveying devices, it is transported into the furnace of the boiler. At high temperatures above 700°C, it is activated and gasified, instantly undergoing a series of chemical reactions with NOx in the flue gas, reducing it to N2 and H2O. This process inhibits the formation of NOx at the source and achieves the goal of NOX removal. The reaction equation is:

       CnHmNs (scientific name: polymer denitrification agent) + NOx = CO2  +  N2  +  H2O

      Technical Features of Polymer PNCR Denitrification Process

       2. Simple denitrification process, convenient to use, and highly flexible spatial arrangement

       3. Low one-time investment cost for the project

       4. Low energy consumption during the flue gas denitrification process and low operating costs

       5. No harmful by-products are generated, and no secondary pollution is formed

       6. Provides energy-saving and clean effects

       7. High safety of the denitrification system
