In modern industrial production, industrial boilers are widely used, which can effectively reduce the emissions of nitrogen oxides, effectively reduce the burden on the atmospheric environment, optimize the production process, improve energy efficiency, and achieve a win-win situation of sustainable development and economic benefits.

In modern industrial production, industrial boilers are widely used, mainly for production and life to provide heat energy, but also to convert heat energy into mechanical energy or electrical energy. With the development of technology and the improvement of environmental protection requirements, industrial boilers will continue to develop in the direction of high efficiency, energy saving and low pollution in the future.

Industrial boilers in the combustion process will produce a variety of pollutants, mainly including: nitrogen oxides NOx, sulfur dioxide SO₂, carbon dioxide CO₂, carbon monoxide, heavy metals and toxic substances, unburned volatile organic compounds and so on. During boiler combustion, nitrogen and oxygen react to produce nitrogen oxide under high temperature conditions, which is one of the main pollutants emitted by boiler combustion, which is harmful to the environment and human health.

In order to reduce pollutant emissions, industrial boilers usually adopt a series of environmental protection measures to reduce pollutant emissions and reduce the impact on the environment and public health. In order to control NOx in the exhaust gas of diesel engine, selective catalytic reduction method (SCR) takes advantage of NH₃ or urea as a reducing substance. Under a certain temperature and catalysis, NH₃ ₃ takes advantage of NH₃ to reduce NOx into N₂ and H O, effectively reducing pollutant emissions, saving the operating costs of enterprises to a certain extent, and contributing to improving the green image of enterprises.

The following is our project on nitrogen oxide treatment of gas fired boilers

Help a company in Guangdong 10t gas boiler to achieve ultra-low nitrogen oxide emissions

Project: A company in Guangdong 10t gas boiler denitration

Process: SCR denitration

Emission index: NOx decreased from 80mg/Nm3 to 30mg/Nm3

Through this transformation, the company has significantly reduced nitrogen oxide emissions, effectively reducing the burden on the atmospheric environment, while optimizing the production process, improving energy efficiency, and achieving a win-win situation of sustainable development and economic benefits. We will continue to uphold the concept of green development, continue to explore and practice more environmental protection technologies, and contribute to the protection of the earth home.
