GE’s CL.AIR* Exhaust After-Treatment System
The CL.AIR® Exhaust After-Treatment System for GE’s Jenbacher gas engines is a thermal regenerative post-combustion system for engine exhaust gases. Since no catalytic reactions take place during the thermal treatment of the exhaust, as it is insensitive to impurities in the fuel gas, the CL.AIR® system is particularly suitable for use with critical gases such as biogas, for which catalytic converters either cannot be used or are used only to a limited extent. In addition, CL.AIR® decomposes the unburned methane in the exhaust gas and provides extra exhaust heat.
Features & Benefits
Features:
- Once exhaust gas is heated to approximately 1,472 °F (800 °C), uncombusted hydrocarbons, formaldehyde, and CO oxidize to form water vapor and CO2
- Catalytic reactions are eliminated during the thermal treatment of the exhaust
- Only minimal power supply is required
Benefits:
-
Resistant to contaminants in the fuel gas
- Minimal maintenance costs
-
Suitable for operation with critical gases
-
Resistant to deposits
-
Constant emission values throughout the entire lifecycle
-
No additional fuel gas cleaning required
- Additional heat generation (about 20-30°C increase in exhaust temperature)
