In order to encourage enterprises to renovate boilers with substandard emissions, the government department in Dongguan, Guangdong Province, issued relevant government subsidy policies for boiler low-nitrogen renovation. Within a certain period of time, subsidies are given. Among the subsidies of 216 million yuan, enterprises can get up to 48% of the subsidy. For energy conservation and emission reduction, the Dongguan government will pay more and more attention to the construction of new energy. The implementation of this policy is an important measure for the comprehensive demonstration city to reduce air pollutants.

Gas-fired boiler is a kind of boiler products fueled by natural gas, which is one of the most widely used fuels after coal-fired boilers. With the further strengthening of people's awareness of environmental protection and the implementation of national environmental protection policies, the nitrogen oxides discharged by traditional natural gas boilers can no longer meet the air pollution standards, and it is necessary to reform it to reduce the nitrogen oxide content.

The main purpose of boiler low nitrogen transformation is to reduce the emission concentration of nitrogen oxides. NOx is determined by the combustion technology of the boiler itself, so nitrogen oxides are the factors that exceed the standard of fuel and gas boilers, unlike particulate matter and SO2, which can be controlled by fuel. The following are two ways of reforming low nitrogen room of natural gas boiler.

Replace the boiler burner. For small natural gas boilers, when low nitrogen combustion transformation is carried out, only the boiler body is not reformed, and the burner is replaced.

Replace the low-nitrogen gas boiler as a whole. Is to buy new environmental protection low nitrogen gas boiler products. However, this cost is higher than replacing the boiler burner.
