What is the temperature and pressure of steam in a coal fired

Large generating stations typically feed steam at above 3000 psi and 1000° F to their high-pressure turbines. There have been units built at significantly higher pressures, above 3800 psi and 1100° F. Nuclear turbines run at very much lower temperatures and pressures, typically 900 psi and 530° F.

Combined-Cycle Power Plant How it Works | GE Power Generation

A combined-cycle power plant uses both a gas and a steam turbine together to produce up to 50 percent more electricity from the same fuel than a traditional simple-cycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power. Improve Performance with Digital.

Power Generation/Steam Power - Wikiversity

A steam/thermal power station uses heat energy generated from burning coal to produce electrical energy. This type of power station is widely used around the world. This power station uses the Rankine cycle. This is the cycle of the steam produced in the boiler, then taken to the Steam turbine ( prime mover ). From the turbine the steam is

Coal-Fired Boiler - an overview | ScienceDirect Topics

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

Steam power station basically works on the Rankine cycle. Steam is produced in the boiler by utilising the heat of coal combustion. The steam is then expanded in the prime mover (i.e steam turbine ) and is condensed in a condenser to be fed in to the boiler again. The steam turbine drives the alternator which converts mechanical energy of the
