White ash lime kiln SCR denitrification equipment manufacturer.
SNCR denitrification is a process that everyone is familiar with, which is to spray the reducing agent (AN water) into the furnace in the range of 800 to 1050 degrees, and reduce the nitrogen oxides into nitrogen and water at high temperatures, so as to achieve the emission of nitrogen oxides up to the standard, and the denitrification efficiency is greater than 50%. Then there is the SCR denitrification outside the furnace, which is to catalyze the flue gas at a temperature of 200 400 degrees.
The agent realizes the reduction reaction, reduces the nitrogen oxides into nitrogen gas and water, realizes the emission of nitrogen oxides up to the standard, and the denitrification efficiency is greater than 90%.
What if the NOx emissions exceed the standard?What if the emissions do not match the protection?Is there a cheaper way to do it besides SCR denitrification and SNCR denitrification?Polymer denitrification is a kind of boiler denitrification technology transformation, after the transformation, the emission of nitrogen oxides is not only better than the air pollutant emission standard, but also energy saving 20%-40%. After the transformation, the cost of denitrification and denitrification is about 30% lower than the previous denitrification technology, and the technology can be applied to industrial boilers, such as coal-fired boilers, gas boilers, oil-fired boilers and other boilers commonly used in China, and is also suitable for denitrification of various kilns, such as white ash kilns, lime kilns, magnesium oxide kilns and a series of kiln denitrification.
