Abstract

The flue gas emissions of thermal power units are widely concerned because of the increasingly strict environment protection requirements. This paper aims at the optimization of flue gas denitrification control for thermal power units. The research introduces the selective catalytic reduction flue gas denitrification system, establishes the first-order model of spaying ammonia system by step response of controlled system, and determines the PID controller parameters following the internal model control tuning rule. The automatic control strategy of spaying ammonia system based on internal model control is given. The application of a 300 MW unit and a 600 MW unit shows the effectiveness of the control strategy.
