In the power industry, backup generator sets are the foundation for ensuring the stable operation of the power grid. When the main power grid suddenly fails or the power supply system is interrupted due to extreme weather, the backup diesel generator sets need to be started immediately to provide uninterrupted power support for more data centers, substations, and key equipment in power plants. However, in our daily lives, backup diesel generator sets generate a large amount of black smoke (high concentration of carbon particulate matter PM) and nitrogen oxides NOx during operation. If not effectively treated and directly discharged, it can not only exacerbate regional air pollution, but also violate local environmental emission standards, bringing risks such as fines and shutdowns to enterprises.
As a technology-based enterprise in the field of industrial exhaust gas treatment in China, Green Valley Environmental Protection has developed an integrated exhaust gas comprehensive treatment solution of “black smoke treatment+denitrification” to address the core characteristics of frequent start stop, large emission fluctuations, and continuous operation of backup generator sets in the power industry. This solution not only solves the problems of black smoke visual pollution and excessive particulate matter, but also achieves low nitrogen emissions of NOx, providing dual guarantees for environmental compliance and safe power supply in the power industry.
Compared with conventional units, the exhaust emissions of backup generator sets in the power industry have significant characteristics, which also bring more complex governance challenges. The NOx emissions of backup generator sets fluctuate with combustion temperature, and conventional fixed parameter governance equipment is difficult to adapt. The requirements for hyperspace and safety are strict. Backup generator sets are arranged near substations and power plant control rooms, with compact space to avoid affecting the emergency start-up of the units and prevent the safety risk of reducing agent leakage.
Green Valley Environmental Protection’s comprehensive tail gas treatment plan for backup generator sets in the power industry is designed with high efficiency purification, safety and reliability, low resistance and energy saving as the core. It consists of a particle trap (black smoke treatment) and low-temperature SCR denitrification (NOx treatment), which can be flexibly combined according to the unit capacity and emission requirements. Green Valley Environmental Protection’s particle trap uses metal felt filter material made of 316L alloy metal wire imported from France, which has the advantages of corrosion resistance, renewability, low back pressure, and high efficiency. The treated tail gas has a stable Ringman blackness below level 1.
The SCR denitrification system independently developed by Green Valley Environmental Protection has independent intellectual property rights and multiple invention patents. At the same time, it has accumulated a large amount of experience data in the application field, which can ensure that the project design is suitable, the operation is stable and reliable, and meets the latest national environmental protection requirements. The nitrogen oxide ultra-low emission and ammonia escape are less than 3ppm requirements. In the field of ultra-low emissions of nitrogen oxides, achieving compact structure, intelligence, precise injection, early warning, data acquisition and management, remote control, online transmission and other functions can ensure that ammonia escape is less than 3ppm while achieving ultra-low emissions, possessing strong comprehensive competitiveness.

Against the backdrop of the “dual carbon” goal and environmental standards, the exhaust treatment of backup generators in the power industry focuses on technical adaptability. Through the integrated solution of “black smoke+denitrification”, it not only solves the special emission pain points of backup generators in the power industry, but also considers emergency safety and long-term benefits, providing a reliable exhaust treatment solution for the green transformation of the power industry.
