Steam Power Plants use a variety of resources such as coal, oil and natural gas as fuel to generate power. MHI group has an extensive record in meeting the global demand of conventional thermal power stations, including providing highly-efficient ultra-supercritical pressure boilers with an output of over 1,000MW. We also offer proprietary
Steam turbines are often secondary in the power-generation process because the steam must first be heated by the fuel's combustion (boilers) or the exhaust gas (HRSG). In both turbines, the gases (steam or combustion gas) are forced through the turbine blades because of their high pressure and temperature, which spins the turbine (mechanical energy).
The Huaneng Yuhuan power plant located on the coast of East China's Zhejiang Province has China's first 1,000MW ultra-supercritical pressure boilers.
