Unfortunately, catalysts are temperature sensitive and only operate efficiently between 650 F to 800 F. LowNOx burners and flue gas recirculation are other options for reducing NOx emissions.

A twist on an old technique, flue gas recirculation, helps prevent slagging in the upper furnace and convective pass, according to pilot testing recently completed by APTECH CST and the Southern ...

The internal flue gas recirculation of the new burner has been significantly intensified so that both the combustion air and the fuel mix with the flue gases internally before the ignition front.

Technology Most ultra-low-NOx burners employ some level of air-fuel premixing and utilize higher levels of excess air and external flue gas recirculation (EFGR) to achieve lower NOx. ClearSign’s Core ...

FEPCRC developed Oxy-CFBC technology with flue gas recirculation system for the first time in Korea. This Oxy-CFBC process is one of the most advanced technologies that can be operated at 60% of ...

Coal plants often use a process called “flue gas recirculation” that pulls some exhaust gas into the firebox to help reduce pollutant emissions.

Flue Gas Recirculation (FGR): The technique of reintroducing a portion of exhaust gases into the sintering process to improve combustion efficiency and reduce emissions.
