Tungsten Trioxide Helps Catalyze SCR Soot Denitrification Technology
The nitrogen oxides produced by coal combustion as a pollutant will affect human health. The most harmful is NO 2 , which mainly affects the respiratory system of human beings, and can cause bronchitis and emphysema. SCR selective catalytic reduction technology has become the most widely used and most effective flue gas denitrification technology in the world. It has the advantages of low reaction temperature, high purification rate, reliable operation and small two pollution. After its catalysis, the main non-toxic and non polluting N 2 and H 2 O are produced. In the SCR soot denitrification technology selective catalytic reduction system, it is generally composed of ammonia storage system, ammonia and air mixing system, ammonia injection system, reactor system and monitoring control system, the thermal power plant, SCR reactor is usually installed in the boiler economizer and air preheater, here for the high dust temperature arrangement, smoke temper...
