What is a Heating furnace denitrification? Introduction to the principle of SCR denitration system structure

Heating furnace denitrificationthe full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.，at work,Under the action of catalyst, reducing agents (such as ammonia, urea, etc.) react with nitrogen oxides in flue gas to convert them into harmless nitrogen and water vapor.，the product looks atmospheric.，was developed and designed by One-combustion energy saving。

1、Brief introduction of Heating furnace denitrification

Heating furnace denitrificationit refers to the process of removing nitrogen oxides from flue gas to reduce environmental pollution. NOx is a pollutant harmful to the atmospheric environment, which has strong irritation and toxicity, and will lead to environmental problems such as acid rain and photochemical smog, and also endanger human health. The main principle of flue gas denitrification technology is to reduce NOx to nitrogen and water by adding appropriate reducing agent or catalyst in the combustion process or flue gas treatment system, so as to reduce NOx emission.，is a Heating furnace denitrification newly developed by One-combustion energy saving。

4、Structural advantages of Heating furnace denitrification

The Heating furnace denitrification has the following structure

1. Flue gas mixing and distribution system

Ensure that the flue gas and reducing agent are fully mixed in the reactor to improve the denitrification efficiency.

2. Temperature control and monitoring system

It is used to monitor and control the temperature of the reactor to ensure that the chemical reaction is carried out in the optimal temperature range.

3. Reactor

It is the core component of Heating furnace denitrification technology, and it is equipped with catalyst to promote the chemical reaction between reductant and NOx.

4. Catalytic reduction reaction

Under the action of catalyst, the reductant and NOx in flue gas undergo selective catalytic reduction reaction to generate nitrogen and water vapor.

5. Reducing agent supply

Reducing agents such as liquid pure ammonia or ammonia water (aqueous solution of ammonia) are evaporated and mixed with diluted air or flue gas.

5、Heating furnace denitrification principle

Heating furnace denitrificationin the course of work,Ammonia gas or other suitable reducing agent (such as urea aqueous solution) is sprayed into the flue gas upstream of the catalyst at high temperature. Under the action of catalyst, the reducing agent selectively reacts with nitrogen oxides (NOx) in flue gas to generate pollution-free nitrogen and water vapor. Because NH3 is selective, it only reacts with NOx and basically does not react with O2, so this technology is called selective catalytic reduction denitrification.，it has the characteristics of Economically feasible, Strong adaptability, energy saving and environmental protection, Efficient denitration and Strong adaptability，the product looks beautiful.，has been favored by more and more customers.。
