  2. Recovery boiler - Wikipedia

    en.wikipedia.org/wiki/Recovery_boiler

    The invention of the recovery boiler by G.H. Tomlinson in the early 1930s was a milestone in the advancement of the kraft process. [1] Recovery boilers are also used in the (less common) sulfite process of wood pulping; this article deals only with recovery boiler use in the kraft process.

  3. Boiler blowdown - Wikipedia

    en.wikipedia.org/wiki/Boiler_blowdown

    A steam boiler evaporates liquid water to form steam, or gaseous water, and requires frequent replenishment of boiler feedwater for the continuous production of steam required by most boiler applications. Water is a capable solvent, and will dissolve small amounts of solids from piping and containers including the boiler.

  4. Stirling boiler - Wikipedia

    en.wikipedia.org/wiki/Stirling_boiler

    The original boilers were developed to burn coal, but they have been used since to burn many sorts of wood or plant waste. A chain-fed automatic stoker may also be fitted, where a heavy firing rate is required. The three-drum form is also used as a heat-recovery boiler, using the exhaust gases from steelworks or other industrial processes. [2]

  5. Boiler design - Wikipedia

    en.wikipedia.org/wiki/Boiler_design

    Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water to generate steam. Steam produced in a boiler can be used for a variety of purposes including space heating, sterilisation, drying, humidification and power generation. The temperature or condition of steam required for ...

  6. Thimble tube boiler - Wikipedia

    en.wikipedia.org/wiki/Thimble_tube_boiler

    The field-tube boiler uses downward-pointing vertical tubes and these also have an internal tube. This extra tube segregates the flow into a central cold downcomer and an upwelling outer flow of heated water and boiling steam. In the thimble tube, there is no such segregation and so boiling is a random process with flow back and forth along the ...

  7. Supercritical steam generator - Wikipedia

    en.wikipedia.org/wiki/Supercritical_steam_generator

    A new type of heat-recovery steam generator based on the Benson boiler has operated successfully at the Cottam combined-cycle power plant in central England. The vertical tubing in the combustion chamber walls of coal-fired steam generators combines the operating advantages of the Benson system with the design advantages of the drum-type boiler.

  8. Yarrow boiler - Wikipedia

    en.wikipedia.org/wiki/Yarrow_boiler

    The now-asymmetric boiler could pass all of its exhaust gas through the superheated side as the single flow type. [10] The other bank remained in use for purely radiative heating, often with fewer rows of tubes. Alternatively the 'double flow' boiler retained full gas flow through both sides, although only one of these contained a superheater.

  9. Velox boiler - Wikipedia

    en.wikipedia.org/wiki/Velox_boiler

    A Velox boiler is a turbocharged, forced circulation, water-tube boiler which utilises an axial flow compressor and a gas turbine. Velox (Latin: "fast") boilers, also known as Velox steam generators, were developed in the early 1930s by the Brown Boveri Company (BBC) of Switzerland. [ 1 ]
