Abstract
PURPOSE: To control the prescribed quantity of injecting ammonia, by finding total quantity of NOx in exhaust gas from the flowing quantity of gas and NOx concentration in said gas at the ammonia reduction denitration method of exhaust gas.
CONSTITUTION: Pressure difference of optional two points between the fire furnace 2 and the coal economizer 3, is measured and measure value is sent to the operator 15 from the pressure difference transmission equipment 16 at the process of denitrating NOx in exhaust gas by the reduction of ammonia. And, total quantity of NOx in the exhaust gas is calculated by the operator 14 from the signal of flowing quantity of the economizer inlet exhaust gas and signal of concentration of NOx from the NOx concentration transmission equipment 13. Moreover, a fixed supply quantity of NH3 is found by the controller 12 from the signal of total quantity of NOx and that of flowing quantity of NH3 from the NH3 flowing quantity transmission equipment 11 and then, an opening degree of the NH3 flowing quantity control valve 9 is adjusted. Thus, a highly reliable denitration is carried out.
