  2. Boiler feedwater pump - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater_pump

    A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler.The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler.

  3. Pressuretrol - Wikipedia

    en.wikipedia.org/wiki/Pressuretrol

    A pressuretrol is a control used to control a steam boiler, by setting when the boiler should begin and end firing based on steam pressure. The pressuretrol is ...

  4. Control system - Wikipedia

    en.wikipedia.org/wiki/Control_system

    The control action is the switching on/off of the boiler, but the controlled variable should be the building temperature, but is not because this is open-loop control of the boiler, which does not give closed-loop control of the temperature. In closed loop control, the control action from the controller is dependent on the process output.

    en.wikipedia.org/wiki/ASME_Boiler_and_Pressure...

    This committee put in the form work for the first edition of the ASME Boiler Code - Rules for the Construction of Stationary Boilers and for the Allowable Working Pressures, which was issued in 1914 and published in 1915. [5] The first edition of the Boiler and Pressure Vessel Code, known as the 1914 edition, was a single 114-page volume.

  6. Boiler - Wikipedia

    en.wikipedia.org/wiki/Boiler

    Boilers generally have 2 or 3 pressuretrols: a manual-reset pressuretrol, which functions as a safety by setting the upper limit of steam pressure, the operating pressuretrol, which controls when the boiler fires to maintain pressure, and for boilers equipped with a modulating burner, a modulating pressuretrol which controls the amount of fire.

  7. Forced circulation boiler - Wikipedia

    en.wikipedia.org/wiki/Forced_circulation_boiler

    A forced circulation boiler is a boiler where a pump is used to circulate water inside the boiler. This differs from a natural circulation boiler which relies on current density to circulate water inside the boiler. In some forced circulation boilers, the water is circulated at twenty times the rate of evaporation. [1]

  8. Boiler feedwater - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater

    Boiler water is treated to prevent scaling, corrosion, foaming, and priming. Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range. These chemicals are mostly oxygen scavengers and phosphates. The boiler water also has frequent blowdowns in order to keep the chloride content down.

  9. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    A district heating system uses centrally located boilers or water heaters and circulates heat energy to individual customers by circulating hot water or steam. This has the advantage of a central highly efficient energy converter that can use the best available pollution controls, and that is professionally operated.
