Simulation Analysis of Secondary Air Control on Combustion Flame and SNCR Technology in a 900 t/d Waste Incineration Furnace.

ABSTRACT: The stable and efficient combustion of large-capacity waste incinerators is a critical factor in improving the operational efficiency and safety of the equipment. The present study employs numerical simulation methods to comprehensively analyze the combustion flame characteristics, temperature field distribution, temperature uniformity, and the distance between the high-temperature region and the water-cooled wall in a 900 t/d large-capacity waste incinerator. This is achieved by adjusting the secondary air distribution ratios at the front and rear walls. The findings suggest that under constant secondary air inlet angle conditions, optimizing the secondary air velocity can significantly enhance combustion stability within the furnace. It has been demonstrated that modifying the secondary
