  • Chapter 12 Boiler Deposits: Occurence And Control |

    2019-7-22 · The water in the tube becomes more concentrated, increasing the potential for deposition of boiler water salts. In extreme cases, deposition becomes heavy enough to reduce circulation to a point at which premature steam-water separation occurs. When this happens in a furnace tube, failure due to overheating is rapid.

    Steam Cycle. A steam cycle power plant is operated using the Rankine cycle. Water enters a boiler where it is heated to create steam. The steam is then sent through a steam turbine that rotates the shaft of a generator to create electricity. The steam exits the turbine into a condenser, which converts the steam back into saturated water.
