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.
Since most of the water needs in thermal power plants are for cooling, the amount of water required by the power plant will depend on the type of cooling system used (and not as much on the fuel type). Thus, a Type X plant with dry cooling will certainly require less water than a Type Y plant with cooling towers, for example.
Jan 06, 2020· Most traditional power plants make energy by burning fuel to release heat. Thus, they are called thermal (heat-based) power plants. They burn fuel with oxygen to release heat energy, which boils water and drives a steam turbine. This is majorly the one used by coal and oil plants. Natural gas uses a different process.
Other key issues. Siting: The geographic location of power plants has a huge impact on cooling technology options, water availability, type of water used for cooling, and environmental impacts.Solar and geothermal power plants, for example, must be sited in areas with high solar radiation and geothermal energy, respectively—locations that may be arid and far from conventional water resources.
