  • American High-Pressure Steam Locomotives

    The HS-1a used the Schmidt High-pressure System, in which a sealed (and hence scale-free) ultra-high-pressure steam circuit transferred heat to a high-pressure boiler, by means of heating coils inside it.The hot gases from the HP boiler were then passed through a conventional fire-tube low pressure boiler. The HP boiler generated steam at 850 psi, feeding the central cylinder.Learn More

  • Boiler feedwater - Wikipedia

    History of feedwater treatment. During the early development of boilers, water treatment was not so much of an issue, as temperatures and pressures were so low that high amounts of scale and rust would not form to such a significant extent, especially if the boiler was "blown down". It was general practice to install zinc plates and/or alkaline chemicals to reduce corrosion within the boiler.Learn More

    3.Two types of high pressure water tube boilers are specified, flex tube and D-type. The two boiler types are significantly different, and only one of the two types should typically be specified if all new boilers in a given project are similar. 4.Flex tube boilers: a)Primarily for non-critical service firing gas fuel and with stable steam demands.Learn More

  • Unit I Water Technology.

    Various advantages of water tube boilers are as follows: (i) High pressure of the order of 140 kg/cm2 can be obtained. (ii) Heating surface is large. Therefore steam can be generated easily. (iii) Large heating surface can be obtained by use of large number of tubes. (iv)Because of high movement of water in the tubes the rate of heatLearn More

    The high pressure feed water is supplied to the boiler through this valve. This valve opens towards the boiler only and feeds the water to the boiler. If the feed water pressure is less than the boiler steam pressure then this valve remains closed and prevents the back flow of steam through the valve.Learn More
