    Understanding Draft | Beckett Corp.

    The amount of vacuum is called draft intensity. Draft volume specifies the cubic feet of gas that a chimney can handle in a given time. Draft intensity is measured in “inches of water”. Just as a mercury barometer is used to measure atmospheric pressure in inches of mercury, a draft gauge is used to measure draft intensity (pressure) in inches of water. Natural Draft is thermal draft. It occurs when …

    Draft - Combustion Technology

    Forced draft boilers run a positive pressure from overfire, through to the stack termination. The entire system must be welded or otherwise sealed tightly to prevent flue gases from escaping. Also, the height of the vent termination must be limited (generally 15 feet from the breech) to prevent a negative draft.

    Draft Measurement Guide for Chimneys & Flues

    DRAFT REGULATOR, DAMPER, BOOSTER, a barometric draft control, also called a "damper" or barometric damper, is a hinged, weighted door on an opening at a heating flue. Barometric dampers are used on oil-fired heating appliances (furnaces, boilers, water heaters) to assure constant draft and thus uniform combustion.

    Induced Draft Fan. The hot flue gases from the furnace is drawn out by the Induced draft fan. The gases passes through the various heating surfaces of the boiler, the Electrostatic Precipitator and discharges to the atmosphere at the top of the stack. Induced Draft Fan provides the energy for this flow of flue gases.
