Coal-fired, biomass, oil-fired and other industrial boilers will produce pollutants to varying degrees, so what gas pollutants are emitted by gas-fired boiler rooms? What are the emission environmental protection requirements? Let's learn about it with XinLi boiler.

Gas Boiler Pollutant Emissions

　　There are many gas pollutants produced by fuel combustion in gas boilers, such as carbon monoxide, hydrocarbons, nitrogen oxides, as well as sulfur dioxide, hydrogen sulfide and soot, etc. The specific introduction of each is as follows:

　　1. Carbon monoxide, carbon monoxide is a substance that is relatively harmful to human health, and it is easy to cause hypoxic damage to humans and animals, especially for patients with common heart disease, anemia and respiratory diseases.

　　2. Hydrocarbons, the main component of natural gas is that hydrocarbons will not cause direct harm to the human body, but if they are not completely burned, they will produce 3,4-phenylpropane, etc., which are easy to cause cancer.

　　3. Nitrogen oxides. Nitrogen oxides often refer to NO and NO2. The pollution of nitrogen oxides to the environment has become a serious global problem with serious environmental pollution. The current requirements for nitrogen oxide emissions from boilers are particularly strict.

　　4. Sulfur dioxide, the sulfur dioxide produced by the combustion of natural gas boilers is relatively small. The main component of natural gas is methane, and sulfide is an impurity.

Environmental requirements for gas boilers

　　The gas-fired boiler currently requires attention to the emission of nitrogen oxides. For example, the NOx emission in the Beijing-Tianjin wing area requires the emission standard of nitrogen oxides to reach 30 mg or less. In other places, due to different regions, the emission standards are different. However, with environmental pollution problems Increasingly serious, as a large-scale industrial energy-consuming equipment, the pollutant emission of boilers will become more and more strict.

　　For this reason, the manufacturer chooses the boiler model reasonably according to the local environmental protection requirements, and the second is to decide whether to choose the boiler with ultra-low nitrogen oxide emission for operation according to the trend of pollution regulations in the industry, so as to avoid the re-regulation of environmental protection. Boiler equipment replacement or other problems bring production to a standstill, resulting in losses.
