Abstract
This paper studies existing problems in automatic control for NOx emission of one homemade 600 MW supercritical coal-fired unit and analyzes reasons for unsatisfactory control on NOx concentration at the exit of chimney. It proposes and implements comprehensive optimization methods of improving denitration temperature protection,optimizing boiler com-bustion control strategy and adding forecast control and dynamic feedforward in ammonia spraying control so as to realize target of ultra low emission of making NOx emission concentration less than 50 mg/m3 as well as ensure monitoring data reach to emission level of the gas turbine.关键词
