  • Controlling TDS in the Boiler Water

    As a boiler generates steam, any impurities which are in the boiler feedwater and which do not boil off with the steam will concentrate in the boiler water. As the dissolved solids become more and more concentrated, the steam bubbles tend to become more stable, failing to burst as they reach the water surface of the boiler.

  • Pressurised Deaerators

    However, for high-pressure water-tube boilers and steam plant handling superheated steam, it is vital that the oxygen level in the boiler water is kept much lower (typically less than seven parts per billion - 7 ppb), because the rate of attack due to dissolved gases increases rapidly with higher temperatures.

  • Steam locomotive - Wikipedia

    2021-9-1 · A steam locomotive is a rail vehicle that provides the force to move itself and other vehicles by means of the expansion of steam.: 80 It is fuelled by burning combustible material (usually coal, oil or – now rare – wood) to heat water in the locomotive's boiler to the point when it becomes gaseous and its volume increases 1700 times. Functionally, it is a steam engine on wheels.
