Most electric power is produced by steam turbines. This is because the steam cycle is well suited to the conversion of heat to work and steam turbines can be built in a wide range of capacities up to about 1500 MW. Steam turbines are basically very simple having fixed blades to accelerate the steam and moving blades to absorb the resulting kinetic energy. The moving blades are mounted on a rota...

In power station practice, work is extracted from expanding steam in three stages namely High Pressure(HP), Intermediate Pressure(IP) and Low Pressure(LP) turbines. During the expansion process in the LP turbine, the steam cools down and at some stages, it nucleates to become a two-phase mixture. It is well-acknowledged in the literature that the nucleating and wet stages in steam turbines are ...

A reliability model for a power generating system comprising two gas turbines and one steam turbine is developed wherein scheduled inspection is done at regular interval of time for maintenance. Initially, all the three units i.e. two gas turbines as well as one the steam turbine are operating and working of the system is called the working at full capacity. On failure of one of the gas turbine...

Due to the importance of energy consumption in a steam network of oil refinery as a significant unit, present study is concerned with the optimization of an oil refinery steam network. Here, the attempt was made to use concepts such as first and second thermodynamic laws, thermo-economic, environmental and economic discussions to investigate three different scenarios about Tehran refinery steam...

Steam turbines employed in the sugar industry require high thermodynamic efficiency and absolute reliability. The AEG-KANIS Steam Turbine Company, situated in Nuremberg, West Germany, and for many years a supplier to the South African industry, developed such turbines based on 30 years of experience with turbines for all industrial purposes. A special feature of these typical turbines used for ...
