Marine boilers produce high pressure superheated steam to drive the turbines. The steam is generated by the water tubes which connect the water drum to the steam drum. Water and steam circulate through the vertical banks of tubes; the inner ones supplying the top drum and the outer ones dropping steam and water back to the water drum.

Mar 19, 2018 · Superheated Steam When saturated steam generated in steam boiler is further passed through a heat transfer surfaces, then its temperature will starts increasing above evaporation or saturation. Steam is described as super heated, if its temperature is more than that of its saturation temperature. Degree of super-heat is directly related
In a boiler, energy from the fuel is transferred to liquid water in order to create steam. Once the water is heated to boiling point, it is vaporized and turned into saturated steam. When saturated steam is heated above boiling point, dry steam is created and all traces of moisture are erased. This is called superheated steam.
water-tube boilers, tubes containing water are heated by combustion gases that flow outside the tubes, while in the fire-tube boilers hot combustion gases flow inside the tubes and water flows outside. Key design parameters to determine the boiler size and power are the output steam mass flow rate, pressure and temperature.
If the saturated steam is moist, the saving due to superheat is more and ordinarily the gain in economy due to superheated steam, for equal boiler efficiencies, as compared with commercially dry steam is, say, 5 per cent for each 100 degrees of superheat.
We manufacture our own electric steam boilers, steam superheaters, condensate return systems, automatic blowdown systems, heat tracing, custom control systems, and perform all skid design and manufacturing in-house.
Super Boiler Background > U.S. industrial and commercial steam boilers – Consume over 6 quads of natural gas per year – Wide range of steam uses from process steam to space heating > Installed base of steam boilers – Largely over 30 years old – Average efficiency 76% – Typical NOx emissions 85 ppmv
May 27, 2019 · What is Boiler:-A boiler is outlined as “A closed vessel during which water or different liquid is heated, steam or vapor is generated, steam is super heated, or any combination therefrom, besieged or vacuum, to be used external to itself, by the direct application of energy from the combustion of fuels, from electricity or energy ”.

In this case, the boiler produces super-heated steam, providing an optimal energy yield. Alternatively, the energy may be recovered in the form of heat to be supplied to an urban heating network or industrial consumers. When the recovered energy is used to produce heat only, a saturated or super-heated steam boiler or a hot-water boiler is used.
