Jan 20, 2018· Flue gas recirculation for NOx control includes gas recirculation into the furnace or into the burner. In this technology 20-30% of the flue gas (at 350-400°C) is re-circulated and mixed with the combustion air. The resulting dilution in the flame decreases the temperature and availability of oxygen therefore reducing thermal NOx formation.
Aug 09, 2018· Overfire air and flue gas recirculation (OAFGR) systems can offer significant benefits to a stoker-fired boiler system, ranging from more efficiency to fewer emissions. Overfire Air and Flue Gas Recirculation Explained. In this configuration, flue gas is taken from downstream of the boiler and combined with combustion air from a draft fan.

OFA and FGR for Emissions Control on Stokers. CC&E engineers have experience designing and installing a combined overfire air (OFA) and flue gas recirculation (FGR) system for stoker boilers for the reduction of NO x, CO, and flyash emissions.CC&E personnel have provided this combined system to multiple stoker boilers, conducting baseline testing, CFD modeling, system design, system
In recent times Circulating Fluidized bed boilers are used for burning lignite especially on smaller capacities units. The lower furnace temperatures help in preventing the slagging . Fluidized bed boiler can dry the Lignite in the furnace during the combustion …
Biomass Fired Boilers. Our engineers have experience in the design and installation of improved overfire air systems and flue gas recirculation systems for stoker boilers burning wood exclusively as well as for stokers that burn wood or coal. The design and installation of these modifications included baseline testing, CFD modeling
Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived
