Research and Application of Automatic Control of Ammonia Injection in Power Plant Based on Artificial Intelligence

Abstract

Environmental protection has attracted increasing attention. Coal-fired boilers, as one of the main sources of nitrogen oxides, have adopted low-nitrogen combustion technology in large-scale coal-fired boilers and promoted denitrification technology in order to reduce the emission of NOx. This paper introduces the energy-saving and automatic control technology of the denitrification system after furnace and its subsidiary equipment. Emphasis is laid on the realization of NOx closed-loop control by using open external advanced control system and large data artificial intelligence prediction.
