4、Structural characteristics of Step furnace denitrification

The Step furnace denitrification has the following structure

1. Flue gas mixing and distribution

The mixed reducing agent and flue gas are fully mixed in the mixing tube and evenly distributed to the catalyst reactor through the distribution system.

2. control system

The whole Step furnace denitrification is automatically controlled, including the adjustment of reducing agent supply, flue gas flow and temperature, so as to ensure the stable operation of the system and achieve the expected denitrification effect.

3. 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.

4. Temperature control and monitoring

The temperature in the catalyst reactor is maintained within the optimal reaction temperature range through the temperature control and monitoring system.

5. Reactor

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

5、Step furnace denitrification application

Step furnace denitrificationWidely used in Improve product quality, Meet the requirements of environmental protection, Flue gas denitrification, Promote sustainable development and environmental protection，is a Step furnace denitrification，at the start of the operation,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.，is an advanced Step furnace denitrification developed by our company in combination with the actual situation of the industry。
