The Interactions Between Steam Piping and Boiler Outlet Headers …

During the operation of a modern steam turbine, moisture in the turbine will cause erosion on the turbine blade. This results in high maintenance costs and loss of power production and thus a loss of revenues that usually is far greater than the maintenance costs. Therefore, all modern fossil power plants use superheated steam, which is conveyed through the "Main Steam Piping" system, and many of the large utility plants use a second super-heater (called a reheater) that reheats the steam after it has passed through a portion of the turbine. This is usually done on a util-ity boiler application after the initial superheated steam passes through the high-pressure section of a turbine. The lower-pres-sure steam from this section of the turbine returns to the boiler, where the steam temperature is increased, and then returns to the turbine through the "Hot Reheat Piping" …

High Pressure Boiler: What is it? Types & Characteristics

A high pressure boiler is a shell and tube heat exchanger that use boiled water to create steam or high pressure hot water. Using water filled tubes in a metal tank or enclosure, they create power by converting water into steam through thermal energy, which is used to power equipment.
