  • Types of Steam Boilers, Parts, Working Principle (PDF)

    Mar 02, 2021 · What is steam boiler? The steam boiler also known as the steam generator is, usually a closed vessel made up of steel. In a steam boiler, the water is converted into steam by the application of heat.Fuels, which are commonly used in boilers, are coal, oil, and gas for producing heat. The steam generated by the boiler is used in various Industries for processing, heating and for running steam Learn More

  • Boiler – Fundamentals and Best Practices

    From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the latent heat decreases Boiler pressures are expressed in psia, psig, bar, kg/cm2, kpa SteamLearn More

    Where a waste heat boiler (economizer- a word form economy) is used to supply steam to a turbo-alternator, control of steam output is normally controlled by a three way valve in the exhaust uptake, the position of which is regulated in accordance with steam demand. Surplus waste-heat is then diverted to a …Learn More
