SCR Denitrification | Boiler emissions: Why is nitrogen oxide control important?

As a widely used industrial kiln, the boiler is widely used in the industrial production process. However, with the efficient combustion process, the production of nitrogen oxides (NOx) has become an environmental problem that cannot be ignored. Nitrogen oxides not only threaten human health, but also have profound effects on ecosystems and climate change. Therefore, it is particularly important to treat the nitrogen oxides discharged from the boiler.

Boiling furnace is a kind of coke preparation equipment for heating pulverized coal by fluidization technology, also known as fluidized bed heating furnace. By suspending the fixed raw material particles such as pulverized coal under the action of air flow, the flow state similar to boiling is formed, so as to achieve efficient heat exchange and combustion. Its working principle is to break up to a certain particle size of coal, blown by the wind, at a certain height of the furnace into boiling combustion.

In addition to the application of boiling furnace in the metallurgical industry, it also plays an important role in the chemical industry, energy field, environmental engineering, material preparation, food industry, pharmaceutical industry, etc., because of its high efficiency and energy saving, full combustion, easy operation and other characteristics, it has been widely used in many industrial fields. With the development of technology, the application range of boiling furnace is still expanding.

NOx is one of the main substances that form acid rain, which can cause damage to soil, water and vegetation, cause respiratory diseases, lead to photochemical smog, and also cause global warming. Therefore, low-nitrogen transformation of boiling furnace is the need to comply with regulations, and it is an important measure for enterprises to fulfill their social responsibilities and protect the environment and human health. Nitrogen oxide treatment will become an integral part of the operation of the boiler.

Our SCR denitration system, with independent intellectual property rights and a number of invention patents, has accumulated a lot of experience in many fields, can ensure that the project design is reasonable, stable and reliable operation, ultra-low nitrogen oxide emissions and ammonia escape requirements of less than 3ppm, meet the latest national environmental requirements. In boiling furnace SCR ₃, NH₃ or urea ₃ is reduced to nitrogen N₂ or water H₂O under a certain temperature and under the action of a catalyst.

As a widely used industrial furnace, the problem of nitrogen oxide emission cannot be ignored. The patented mixing technology of SCR denitrification can ensure the full mixing of ammonia and flue gas, so as to achieve near zero emission of nitrogen oxides.
