flue gas boiler emission standard

Existing standards and regulations on permissible

With Flue gas recirculation (FGR), a percentage of the flue gas is reintroduced into the combustion chamber (as part of the combustion air) to cool the core flame temperature to reduce NOx. FGR does require more horsepower to drive larger fans because of both the increase in mass as well as the increased temperature of the combustion air being

Introduction to biomass boilers - TheGreenAge

May 04, 2015 · Every four weeks or so, the biomass boiler will need to be emptied of the ash. This can be put straight onto a compost heap to help fertilise the soil. Biomass boilers are designed to work all year round; however you may choose to turn them off in the summer. They can be coupled with solar heating or an electric shower, providing you with your hot water for washing only, during the warmer summer months. How does biomass measure up against traditional fuels? Biomass boilers

Flue Gas Recirculation. Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the flame temperature and reduce NOx formation.

1.4 Natural Gas Combustion - US EPA

Currently, the two most prevalent combustion control techniques used to reduce NOx emissions from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox,
