With the development of the global economy and the enhancement of global environmental protection, the standards of industrial emissions are becoming more and more stringent. Stainless steel heating furnace as an important industrial heat treatment equipment, in the combustion process will produce nitrogen oxides (NOx), it is an important source of air pollution, therefore, reducing nitrogen oxide emissions to improve air pollution is of great significance.
The denitrification technology of stainless steel heating furnace is to reduce the generation of NOx in the working process of stainless steel heating furnace, and control the emission of nitrogen oxides by improving the combustion technology and controlling the combustion conditions. In the process of flue gas emission, chemical or physical means are used to reduce the generation of NOx.
Nitrogen oxide emissions can be reduced by:
1, selective catalytic reduction SCR, under the action of the catalyst, the use of reducing agent and NOx chemical reaction, into harmless nitrogen and water vapor, this is the most mature and efficient denitrification technology.
2, by improving the design of the burner, control the temperature of the flame, reduce the generation of thermal NOx.
3, the use of microbial metabolism, NOx into harmless substances.
In practical applications, the denitration technology of stainless steel heating furnace needs to consider cost effectiveness, although the efficiency of SCR denitration technology is high, the initial investment is relatively large, and the catalyst needs to be replaced regularly, we need to choose the denitration solution suitable for ourselves according to the local environmental protection requirements and economic benefits.
The progress of denitrification technology of stainless steel heating furnace can not only effectively reduce environmental pollution, alleviate environmental pressure, improve air quality, but also promote the environmental transformation of green industry, with the continuous progress of technology and cost reduction, denitrification technology will be more widely applied in the industrial field, and play a key role in protecting our natural ecology.
