A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 3,200 psi or 22 MPa.
In April 2017, General Electric (GE) signed its first ever power agreement in Cambodia to supply boilers, electrostatic precipitators, and steam turbine generation systems for a 135MW coal plant being built by Toshiba Plant Systems and Services Corporation.
What is a power boiler? Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
Steam Turbines. A steam turbine is a piece of heavy equipment that rotates blades with the high-temperature, high- pressure steam generated by diverse heat sources – such as boilers for power generation, heat recovery steam generators, nuclear steam generators, and industrial steam boilers – in order to convert into rotational energy.

Course Details. Boiler feedwater often contains inorganic salts, dissolved impurities, and foreign particles, which generate corrosion problems and decrease efficiency due to damage to heat transfer surfaces. Demineralizers use ion exchange resins to remove these impurities in the raw water used for makeup in boiler feedwater.
