  • Flue position on next door house - is it dangerous

    The ideal placement of a boiler flue depends on a number of factors. According to the boiler flue regulations, regard should be given to the following issues when determining the appropriate placement: Distance from windows and doors. A boiler flue should not be placed close to any part of your home that can open, such as windows or doors.Learn More


    B. Flue Gas Recirculation (FGR) systems have an additional issue, because high stack pressures can result in rich burner operation. A higher stack pressure will force more flue gas into the burner, reducing the combustion air flow causing a fuel rich condition with the potential for an explosive condition.Learn More

  • Regulations and standards to be observed. Flue location

    Sep 24, 2018 · Under the boiler flue position regulations, the flue has to be positioned a certain distance from any parts of the home that can be opened up such as windows and doors. How far this is will depend on the size of your boiler but is typically between 30-60cm above, below or to the side of an opening. These measures help to prevent harmful gases from entering the home, after all a boiler flue …Learn More

  • Guide to oil boiler types, positioning and flues

    Oct 12, 2019 · Flue considerations. The position of flue terminals (i.e. where the flue discharges through a wall or roof) is strictly regulated. Oil fired boiler flues must not be terminated beneath windows or where higher parts of the building will affect the draw of the flue or chimney. Condensing flue boilers emit large plumes of water vapour.Learn More

  • RCTFlueGasTreatment |

    NOx control with flue gas treatment involves the reduction of NOx in the flue gas by injecting a chemical reducing agent into the post-combustion region of a combustion unit. The reducing agents, primarily ammonia and urea, convert the NO in the flue gas to molecular nitrogen at high temperatures, between 1,600 and 2,000°F, without a catalyst.Learn More

  • RCTFlueGasTreatment |

    Aug 03, 2018 · The regulations differ for most boiler models depending on their size, but the typical guide is that the flue needs to be at least 30cm away from an opening, such as a window, if it is to be placed above or to the side of said opening. Boilers on the larger side need to have their flues positioned up to 60cm away from those openings.Learn More

  • Flues - an overview | ScienceDirect Topics

    Deposits in the boiler flue passages retard the transfer of heat to the metal and the effect on the overall boiler thermal efficiency depends on the nature and thickness of the deposits and also their position in the flue system. Deposits in the high-temperature zone have a more adverse effect than those in the convection zone.Learn More
