Gas Turbines are widely used for combined-cycle power plants, distributed energy stations and peak-shaving power supply. Gas turbine exhaust features high temperature, large gas flow and frequent load fluctuation. Even for natural gas-fired turbines, NOₓ and CO emissions remain the main challenge to meet increasingly strict local environmental regulations. Green Valley customized SCR exhaust aftertreatment solutions are engineered for gas turbine operating characteristics, delivering stable NOₓ reduction for both simple-cycle and combined-cycle turbine units.
Applicable Products:
1. SCR System (Gas Turbine Version): Core NOₓ abatement equipment for gas turbines. Optimized wide-temperature catalyst, ammonia slip stably controlled below 3ppm. Custom mixing tube and flow field design to fit large exhaust flow, applicable for simple-cycle & combined-cycle gas turbine units.
2. DOC Oxidation Catalyst: Removes CO and residual HC, suitable for gas turbine exhaust with high oxygen content. Can be matched upstream or downstream of SCR.
3. ASC Ammonia Slip Catalyst: Optional add-on, eliminates excess escaped ammonia, prevents secondary pollution, ideal for ultra-low emission projects.
Note: Gas turbine exhaust contains nearly zero particulate matter, DPF is generally not required.
Value & Significance:
Green Valley gas turbine SCR systems adopt high-temperature resistant catalyst modules, adapted to frequent start-stop and wide-range load variations of peak shaving gas turbines. CFD optimized mixing design ensures uniform urea/ammonia distribution, maintaining high denitrification efficiency while keeping low backpressure with no impact on turbine output. The system helps energy operators meet local ultra-low NOₓ emission standards, pass environmental compliance audits and avoid emission penalties for distributed power and combined-cycle projects.
