    Oct 30, 2019 · The selection of fuel to burn in the boiler is the first opportunity to reduce flue gas contaminants. For example, natural gas burns cleaner than fuel oil, medical waste, or biomass and produces the least amount of pollutants in its flue gas. Natural gas is considered a low-nitrogen fuel and yields very little NOx as a by-product of combustion.

  • 1.4 Natural Gas Combustion - US EPA

    Improperly tuned boilers and boilers operating at off-design levels decrease combustion efficiency resulting in increased CO emissions. In some cases, the addition of NOx control systems such as low NOx burners and flue gas recirculation (FGR) may also reduce combustion efficiency, resulting in higher CO emissions relative to uncontrolled boilers.

  • Flue dilution system | Jeremias UK - chimney systems

    Flue Dilution systems are an alternative option to a standard conventional boiler flue, which may offer a solution to any potential termination issues encountered with a conventional flue. The idea of Flue Dilution is to dilute the flue gases to less than 1% CO2 and 5ppm Nox in order for the flue gases to be safe for a low level or horizontal

    flue gas recirculation. Low NOx burners reduce NOx by accomplishing the combustion process in stages. Staging partially delays the combustion process, resulting in a cooler flame which suppresses NOx formation. The two most common types of low NOx burners being applied to natural gas-fired boilers are staged air burners and staged fuel burners.
