Steam Cycle - an overview | ScienceDirect Topics

The objective function for the steam turbine optimisation is to maximise the thermal efficiency of the power plant which comprises the boiler, steam turbines, condenser, splitter, circulating water pumps and the mixer. The thermal efficiency of the cycle is defined as the ratio of the net work output to the total rate of energy input to the system.

Difference Between Low- and High-Pressure Boilers |

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
