Abstract
PURPOSE: In an apparatus for removing NOx in exhaust combustion gas with NH3 or a reducing substance, the rate and position of feeding of NH3 or a reducing substance are controlled according to the measurement results of temperature distribution and NOx flow rate distribution of the combustion gas whereby sufficient NOx removing effect is obtained.
