    Sep 03, 2019 · All those that I have worked on are not positive pressure in the way that the old boilers are. On the old boilers the fan is on the air intake and pressurises the whole casing. on condensing boilers the fan draws air from within the casing so the main casing is still negative pressure.Learn More

  • Positive Pressure / Negative Pressure Boiler

    Improper gas pressure can cause issues with your furnace if it is not properly set at the time of the installation. Overheating or under-heating can result in problems, ranging from damage to the furnace to not properly heating the space as intended.Learn More

  • Furnace Pressure Switch Stuck Open? | Common Causes

    Boiler furnace pressure is the negative draft maintained by the induced draft fan to ensure the proper flue gas flow throughout its path. Negative pressure in boiler furnace also restrict the flow of flame and flue gas from furnace to atmosphere. PS- there are few packaged boiler also available in which positive draft is maintained.Learn More

    Apr 15, 2014 · Namely, boiler construction. Since then, many more boilers were of brick-set construction, required to be run at negative draft or balanced draft pressure. Because the furnaces were not air tight, the furnace walls were kept cool by a constant stream of cool air drawn in by the slightly negative pressure of the furnace.Learn More

  • What causes a natural gas boiler to backdraft? — Heating

    (Pressure always moves from high to low, we all know). In short, the pressure may be artificially lower within the boiler room/enclosure or artificially high outside the chimney exit, or a combination of both. Armed with that, the first things I look at are sources of negative pressure within the boiler room or affecting the boiler enclosure.Learn More

    May 03, 2017 · Positive pressure :- When the pressure in combustion area of the boiler is more than atmospheric pressure, normally forced draft boilers, HRSG are positive pressure. Negative pressure :-When the pressure in combustion area of the boiler is less than atmospheric pressure. This is achieved in balanced draft boilers by using Forced draft fans to force air into boiler (pressuring it)and Induced draft fans to remove air from the boilers to create negative pressure.Learn More
