For the denitrification of coal powder boilers, our company adopts a dual zone low nitrogen combustion system transformation+SCR selective catalytic reduction technology. Based on the dual zone low NOx coal powder combustion technology, SCR flue gas denitrification technology is added, and the comprehensive denitrification efficiency reaches over 90%, which can achieve the goal of efficient denitrification. On the basis of meeting the latest national emission standards, significantly reduce investment and operating costs. At present, this process has been applied to multiple coal-fired boilers due to its excellent cost-effectiveness, and has reached the international leading level in denitrification of coal-fired boilers.

Under the guarantee of strong slag prevention, coking prevention, and efficient stable combustion technology, the dual zone low NOx combustion technology of coal powder boilers adopts technical measures such as low oxygen combustion, air classification, and low NOx combustion, which can achieve comprehensive benefits of slag prevention, coking prevention, efficient combustion, and low NOx emissions in coal powder boilers.
