Flue Gas Recirculation (FGR) - CCA Combustion Systems

2020-6-24 · Flue Gas Recirculation (FGR) is a powerful nitrogen oxide (NOx) control technique that significantly reduces NOx emissions by recirculating flue gases from the boiler exhaust duct into the main combustion chamber. This process reduces peak flame temperature and lowers the percentage of oxygen in the combustion air/flue gas mixture, thereby reducing thermal NOx formation.

Unreacted ammonia is commonly referred to as ammonia slip, breakthrough, or carryover. The amount of ammonia slip also depends in part on the amount of ammonia injected. Achievable NOx reductions for an individual boiler depend on the flue gas temperature, the residence time at that temperature, the initial NOx concentration, the NH3/NOx ratio
