      Why do gas boilers need to be modified with low nitrogen?

　　 Gas boiler mostly refers to boiler products that burn natural gas as fuel. Since natural gas is a clean energy source, it is a new type of environmentally friendly boiler product and the mainstream product after coal-fired boilers, occupying an important market position.

　　 Gas boiler has many advantages such as high thermal efficiency, environmental protection and energy saving, low operating cost, beautiful appearance, safety and reliability, etc. It is the first choice for users to purchase boiler products. However, with the further strengthening of environmental policies, ordinary gas-fired boilers can no longer meet the environmental policy standards, and the nitrogen oxide content in the exhaust gas of the boiler does not meet the environmental regulations, so the natural gas boiler needs to be modified with low nitrogen.

　　There are generally two ways to transform gas boilers with low nitrogen. One is to replace the boiler and choose new environmentally friendly low-nitrogen gas boiler products. The second is to carry out low-nitrogen transformation of natural gas boilers, that is, to reduce the nitrogen oxide content in the boiler tail gas by replacing the burner or changing the boiler body to meet the low-nitrogen requirements. The common way for ordinary gas boilers to carry out low-nitrogen transformation is to replace the burner, which means that by replacing the new type of low-nitrogen burner, the exhaust emission of the boiler can reach the standard, which can further improve the thermal efficiency of the boiler and meet the boiler use standards.

The nitrogen oxide content in the exhaust gas of ordinary gas-fired boilers is about 150mg per cubic meter. There are three aspects to the standard of low-nitrogen gas boilers. One is that the nitrogen oxide content per cubic meter is 80mg-150mg, which belongs to ordinary gas boilers, and it is 30mg-80mg. Among them are low-nitrogen gas-fired boilers, while those below 30 are ultra-low-nitrogen gas-fired boilers.

　　 Low-nitrogen retrofit of gas boilers is the mainstream form of gas-fired boilers. It has been fully modified in different regions, and boiler products can only be used again after meeting the standards. Therefore, low-nitrogen retrofits for gas boilers are the general trend.
