News - Why Must Gas-Fired Generator Sets Undergo Denitrification? Unveiling the SCR Denitrification Solution for Green Valley Environmental Protection’s Gas-Fired Generator Sets

Nitrogen oxides (NOₓ) are the primary cause of acid rain and photochemical smog. They also exacerbate the greenhouse effect and harm human health. With green environmental protection as its core, Lvgu Environmental Protection is equipped with generator sets featuring high-efficiency exhaust gas treatment systems. These sets can be deployed in scenarios with strict environmental requirements, such as industrial parks and data centers, thereby enhancing market competitiveness. Through denitrification technology, NOₓ is converted into non-toxic and harmless nitrogen gas and water, which not only reduces damage to the ecological environment but also aligns with the core values of the enterprise’s sustainable development. According to China’s emission standards for pollutants from thermal power plants, the emission concentration of nitrogen oxides (NOₓ) from gas-fired generator sets must be controlled below 50 mg/m³, while some key regions require it to be kept below 30 mg/m³. Lvgu Environmental Protection is a national-level high-tech enterprise that has passed the special review and certification. Its main businesses, including the SCR denitrification system and DPF (Diesel Particulate Filter), possess independent intellectual property rights and a number of invention patents. These technologies specifically address the issue of exhaust gas pollutants from generator sets, with a stable denitrification efficiency of over 95%. After treatment, the particulate matter (PM) meets the Ringelmann blackness level 1 standard, with a concentration of 15 mg/Nm³.

The exhaust gas from gas-fired (including natural gas, biogas, etc.) generator sets does not come from “purely clean” fuels. During the combustion process, NOₓ is still generated through two pathways:

Thermal NOₓ: Formed by the reaction of nitrogen and oxygen under high-temperature conditions. The combustion temperature of gas-fired generator sets can reach over 1500°C.
Fuel NOₓ: Generated by the reaction of trace nitrogen elements in the gas with oxygen. Even with low-nitrogen combustion technology, only 30%-50% of NOₓ can be removed. The remaining portion requires in-depth treatment by a denitrification system to meet environmental protection standards.

Equipping with exhaust gas treatment systems ensures the long-term stable operation of generator sets while reducing costs. Through Lvgu Environmental Protection’s exhaust gas treatment, the online monitoring equipment at the inlet and outlet uploads real-time NOₓ concentration data to environmental protection authorities to ensure compliance. The monitoring system simultaneously tracks ammonia slip. In the event of excessive ammonia slip or increased resistance, it automatically adjusts the reducing agent injection volume or triggers catalyst regeneration, thereby ensuring the stable operation of the system.
