Gas generators have become the go-to choice for distributed energy systems and emergency power solutions, thanks to their clean fuel compatibility, rapid response capabilities, and cost-effectiveness. These units are widely deployed in data centers, communication hubs, hospitals, and other critical infrastructure. With tightening global environmental regulations and the push toward carbon peaking and carbon neutrality goals, the efficient operation of gas-powered systems has emerged as a key battleground for industrial emission reduction efforts.
Green Valley Environmental Protection has developed an in-house solution for exhaust gas treatment in gas-fired power generation units through proprietary technologies, achieving a win-win balance between environmental protection and economic efficiency. The company has established a modular and customized technology matrix targeting two primary pollutants—particulate matter (PM) and nitrogen oxides (NOx)—in power plant emissions.
DOCF diesel oxidation catalytic converter and particle trap combined system
DPF: The filter element adopts 316L alloy metal felt filter element imported from France, which is suitable for high exhaust temperature conditions of gas generating units; “water washing regeneration” technology can quickly remove blocked particles in 30 seconds and restore the performance of the filter element, with a service life the same as the unit cycle; The PM capture rate is up to 95%, and the treated exhaust gas quality reaches the first-class Lührmann blackness /15mg/Nm³.
DOCF: The diesel oxidation catalyst DOC and the regenerative particulate collector DPF are combined. The DPF converts carbon monoxide and hydrocarbons in the exhaust gas into carbon dioxide and water, and uses the nitrogen dioxid generated by the reaction to assist the regeneration of the DPF, forming a synergistic purification closed loop and reducing the emission of particulate matter.
TWC three-way catalytic converter
The TWC (Thermal Oxidizer) converts harmful emissions from gas engines—such as carbon monoxide, hydrocarbons, and nitrogen oxides—into harmless carbon dioxide, water, and nitrogen through oxidation-reduction reactions. As the most critical after-treatment device in engine exhaust systems, it contains precious metal catalysts like platinum, palladium, and ruthenium. These catalysts facilitate chemical reactions that meet T4/EU5/China VI emission standards, effectively purifying exhaust gases.
SCR denitration system
Efficient denitration: meet the latest national environmental protection requirements, achieve ultra-low nitrogen oxide emissions and ammonia escape less than 3ppm requirements, with strong comprehensive competitiveness.
Intelligent Control: This system achieves compact structural design, intelligent operation, pre-alarm functionality, data acquisition management, remote control, and real-time transmission in the field of ultra-low nitrogen oxide emissions. Utilizing patented mixing technology, it ensures thorough blending of ammonia gas with flue gas to enable precise metering and injection, thereby maintaining stable compliance with emission standards under varying load conditions.
As the proportion of gas-fired power generation in China’s energy mix continues to grow, environmental governance of exhaust emissions from gas-fired units has gained increasing attention. Green Valley Environmental Protection will keep ramping up technological upgrades, driving emission control from “pollutant reduction” to “carbon resource utilization”. This transformation ensures that the roar of gas-fired generators no longer accompanies smog, but instead becomes a pulsating rhythm of clean development. Through green technology innovation, we are propelling the industry toward a sustainable future.
