Tangshan jinsha burner takes you to know low nitrogen burner

What is low nitrogen combustion technology?

The low-nitrogen combustion technology of jinsha burner is a technology that effectively achieves nitrogen removal efficiency and reduces nitrogen oxide emissions by combining low-nitrogen burner technology with other main measures. During combustion, the fuel produces nitrous oxide and nitrogen dioxide as by-products that can be hazardous to the environment, leading to acid rain and ozone production. In general, nitrogen oxides come from three main sources:
1. Thermal NOx: N in air and fuel is generated at high temperature;
2. Rapid NOx: Hydrocarbon combustion will quickly generate NO in the reaction zone when the fuel is too rich;
3. Fuel-type NOx: The thermal decomposition of nitrogen compounds in the fuel reacts with oxygen to generate NO.

2. What are the benefits of implementing low nitrogen combustion?
By using the low nitrogen burner produced by jinsha burner, you can get the following benefits:
1. Environmental protection: low-nitrogen burners can effectively reduce the emission of nitrogen oxides and reduce environmental pollution;
2. Safety: Low-nitrogen burners can reduce the temperature and pressure in the combustion chamber and reduce the probability of accidents;
3. Energy saving: low-nitrogen burners can improve the thermal efficiency of combustion and reduce energy waste;
4. Economy: The use cost of low-nitrogen burners is relatively low, which can save costs for enterprises.

3. What are the control methods to achieve low nitrogen combustion?
The low-nitrogen combustion technology of jinsha burner mainly revolves around how to reduce the combustion temperature and reduce the generation of thermal NOx, and at the same time consider reducing the generation of rapid NOx through initial rapid mixing. Its main technologies include staged combustion (including air classification, fuel classification), flue gas recirculation (including flue gas external circulation, flue gas internal circulation) and metal fiber surface combustion.

4. What are the methods to control the generation of thermal NO?
The nitrogen oxides generated after the fuel is burned are mainly thermal, that is, they mainly come from the N in the air and fuel, and the flue gas NOx generated at high temperature causes environmental pollution. So how can we better control the formation of thermal NO? You can refer to the following methods:
1. Reduce the combustion temperature;
2. Reduce the oxygen concentration and burn under rich fuel;
3. Shorten the residence time of flue gas in the high temperature zone;
4. Make the combustion proceed far away from α=1.
