  • Maintenance and Overhaul of Steam Turbines WGP42 05

    2014-4-4 · 2.A.1 Steam Turbine Blading Steam turbines produce power by converting the energy in steam provided from a boiler or heat recovery steam generator (HRSG) into rotational energy as the steam passes through a turbine stage. A turbine stage normally consists of a row of stationary blading and a row of rotating blading.

  • Steam Pressure Reduction: Opportunities and Issues

    2013-9-26 · Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler's net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.
