What is Boiler and Condenser Pressure - Rankine Cycle .
Superheating is not typical for nuclear power plants. Typically most of nuclear power plants operates multi-stage condensing steam turbines. In these turbines the high-pressure stage receives steam (this steam is nearly saturated steam – x = 0.995 – point C at the figure; 6 MPa; 275.6°C). Since neither the steam generator is 100% efficient ...Get a Quote

Efficiency factors in natural gas fired steam boile
Boiler 7 has 100 ton/h capacity. High pressure steam is produced at 38 bar and 440°C which represents 79 Gcal/h of thermal power. When this boiler works at 90% efficiency, the thermal power is 71 Gcal/h. Due to the high stack gas temperature of the boiler, a 3.5% efficiency loss occurs and the thermal power reduces by 2.4 Gcal/h to 68.6 Gcal/h.Get a Quote
