According to steam character, steam boiler can be divided into saturated steam boiler and superheated steam boiler. In a boiler, energy from the fuel is transfered to liquid water in order to create steam. At first, cold water gets warmer and receives energy in the form of “sensible heat”, right until the boiling point.
operation of a power plant boiler. The desired deviation range of the outlet superheated steam temperature is generally ± 5 oC from the setpoint. Operating at temperatures outside this range can seriously affect the safety and economics of the boiler and turbine operation. Challenges in
In a steam power plant, high-energy steam, generated in a steam generator, expands through a steam turbine and undergoes changes in pressure, temperature, and heat content. During this process of expansion, the high-energy steam also performs mechanical work.
