Introduction to Natural gas boiler denitrification and SCR denitration advantages and features

Natural gas boiler 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.，it has been widely used in Gas power plant, cement plant, metallurgy, Gas power plant, coal-fired power station and other industries。The following is to introduce the Natural gas boiler denitrification:

2、Natural gas boiler denitrification function

Natural gas boiler denitrificationit has the functions of environmental protection, environmental protection, Improve working conditions, Improve energy efficiency and Promote sustainable development，the full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.，in 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.，the advantage is It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the Natural gas boiler denitrification technology can significantly reduce the concentration of nitrogen oxides (NOx) in flue gas and make it meet strict environmental protection emission standards. This high-efficiency denitration ability is mainly due to the promotion of the catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.、The technology is suitable for many industries and processes, such as coal-fired power plants, iron and steel smelting, cement production and so on. These industries will produce a large number of NOx emissions in the production process, and the Natural gas boiler denitrification technology can provide effective denitrification solutions for them. In addition, the gate technology can be adjusted and optimized according to different flue gas components and emission requirements to meet different denitration requirements.、The by-products produced by the technology are mainly nitrogen and water vapor, which are harmless to the environment and will not cause secondary pollution. Compared with the traditional wet flue gas denitrification technology, the Natural gas boiler denitrification technology does not need to use a lot of water resources and will not produce pollutants such as wastewater, which is more in line with the requirements of environmental protection and sustainable development.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Natural gas boiler denitrification can monitor the composition and emission concentration of flue gas in real time, and automatically adjust the injection amount of reductant and the active state of catalyst to ensure the stability and reliability of denitrification efficiency.、Technology has been developed and applied for many years, and it is mature and stable. The Natural gas boiler denitrification has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the Natural gas boiler denitrification technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.，The price is low and affordable，reliable quality。

2. Small secondary pollution

The by-products produced in the Natural gas boiler denitrification opening process are nitrogen and water vapor, and there is no secondary pollution problem.

3. High denitration efficiency

The denitration efficiency of Natural gas boiler denitrification technology can reach more than 90%, and it is a widely used post-combustion denitration technology at present.

4. energy saving and environmental protection

This technology can effectively reduce NOx emission in flue gas, reduce environmental pollution, and at the same time, it has stable operation and low energy consumption, which meets the requirements of energy saving and environmental protection.

5. selectivity

Under the action of catalyst, the reducing agent mainly reacts with NOx selectively, but less with other components (such as oxygen) in flue gas, thus reducing unnecessary consumption.

4、Working principle of Natural gas boiler denitrification

Natural gas boiler denitrificationCatalysts are used to promote the selective catalytic reduction reaction between reducing agents (such as ammonia and urea) and NOx in flue gas. Under the action of catalyst, the reductant preferentially reacts with NOx to generate harmless nitrogen and water vapor, but hardly reacts with oxygen in flue gas. This chemical reaction is usually carried out in the temperature range of 200-450℃, and the specific reaction temperature depends on the type of catalyst selected.。

5、Natural gas boiler denitrification structure

The Natural gas boiler denitrification structure is introduced as follows:

1. 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.

2. 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.

3. 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.

4. Reducing agent storage and supply system

Used to store and supply reducing agent (such as ammonia or urea solution) to the reactor.

5. 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.
