    CECO CCA - Model FGR - Flue Gas Recirculation

    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 ...

    Process Combustion - Process Heater With Recirculation

    If you want to improve efficiency and reduce NOx then the addition of hot flue gas recirculation is the answer. Fresh air is introduced through the burner and the equivalent mass of combustion products is exhausted into the atmosphere. The residue products of combustion are recirculated back into the combustion chamber.

  • Flue Gas Recirculation Systems

    Flue Gas Recirculation (FGR) acts to reduce NOx formation by reducing peak flames temperatures. In conventional applications, the recirculated flue gas is typically extracted from the boiler outlet duct upstream of the air heater. The flue gas is then returned through a separate duct and hot gas fan to the combustion air duct that feeds the wind ...

  • Dry Flue Gas Cleaning (Dry Absorption, Conditioned Dry Absorption)

    In the process of dry flue gas cleaning, the flue gas, if necessary, is moistened and cooled upstream of the actual reaction stage. This is done, on the one hand, for protecting the filter (temperature) and, on the other hand (if lime is used), for moistening the flue gas up to the dew point range. In order to bind the pollutants contained in the ...

  • ETEC - Model FGR - NOx Control Technologies

    Entropy Technology & Environmental Consultants, LP. (ETEC) offers a far less costly NOx control FGR technology, which eliminates the need for a separate FGR fan and windbox mixing device. This technology, known as induced flue gas recirculation (IFGR), utilizes the FD fan to pull (induce) flue gas from the boiler exhaust duct into the ...

  • ETEC - NOx Control for Air Preheat Systems

    New advancements in combustion control technologies, such as flue gas recirculation (FGR) and low NOx burners (LNB), have made it possible to achieve ultra low NOx levels without using expensive post-combustion flue gas clean-up technology. For some natural draft units it may be possible to meet the most stringent of the NOx regulations with ...

  • ADIOX - Absorbers

    ADIOX tower packing can also be installed separately in a vessel, usually located immediately downstream from a wet scrubber system, where the flue gas is still moisture saturated. This is an advantage compared to installation in a scrubber, as there is no need for a droplet separator and liquid recirculation system. Instead of liquid collecting ...

  • Model FGR - NOx Control for Process Heaters

    Traditionally, Low NOx burners (LNB) have been thought to be the only solution for lowering NOx emissions from fired heaters. However, recent field experience with LNB has been a mixed onei,ii,iii. Due to limited success of LNB alone in achieving ultra low levels of NOx, most burner manufacturers have endorsed Flue Gas Recirculation (FGR). FGR has ...

  • SecoLAB - Model FGD - Semi-Dry Power Plant

    Semi-dry FGD is the best economical concept for industrial and utilities boilers using coal as fuel. It is a dry SecoLAB process consisting in a conditioning tower, a LABloop™ dry reactor, a fabric filter with residues recirculation and humidification in the ActiLAB screw reactor. Sodium Bicarbonate, quick or hydrated lime may be used as ...
