First, how does the gas generator produce NOx (nitrogen oxide) in the process of working?

With the continuous development of our society and economy, environmental protection has become our current and future work. In our daily emissions from coal-fired power plant, nitrogen oxide emissions cause a great harm to human health and ecological environment, especially in our country for the environmental lag, and it is limited to NOx.

NOX is mainly a compound with two elements, NO and NO2. In the fuel combustion process of the generator set, nitrogen in part of the air reacts with oxygen in the burning air at high temperature to produce NOx. The other part is the thermal decomposition of the nitrides in the fuel at high temperatures.

I the process of accelerating industrialization and urbanization, the market share of gas-fired generator sets has increased substantially, and the exhaust gas emission of gas-fired generator has become a waste of energy. The energy of waste heat of gas-fired generator is almost the same as the useful power of gas-fired generator. The exhaust temperature of the gas engine is above 450℃, among which 30% of the heat in the flue gas is discharged into the atmosphere and wasted. With the increasing tension of domestic energy, it is very necessary to improve the efficiency of energy saving and reducing consumption.
