The performance of a power plant can be known from the calculation efficiency in generating sector. Steam plants utilize series energy conversion processes including: chemical into thermal when extracting heat coal as fuel to boilers, mechanical turbines and electrical generators. Like other steam plants, Teluk Sirih PLTU located Bungus Kabung, West Sumatra has same production process. it's jus...

The requirements to be met by the next generation of power plants are subject to various criteria depending on regional considerations. Whereas efficiency together with environmental protection, availability and power generating costs head the list of priorities in the highly industrialized countries, investment costs and financing are becoming increasingly important factors in the growth count...

In this work, two different approaches – an iterative thermodynamic method and a neural network model – are proposed and compared for the modeling of steam turbines. The iterative thermodynamic model can predict steam mass flow, pressure, temperature, enthalpy and power on each turbine drum. The NN model can predict the generated mechanical power. Both models have been trained and validated on ...

Making potable water through desalination plants is a very important process in Iran where clean water is highly required. On the other hand, large amount of fossil fuel sources leads to the development of gas turbine power plants all over the country. Furthermore, Persian Gulf in the south and Caspian Sea in the north could be the main sources for supplying potable water in water scarcity area...

Conceptual design of a waste heat recovery cycle is carried out in attempt to enhance the thermal efficiency of a steam power plant. In the recovery system, super-critical an CO2 is employed as the working fluid operating in a Brayton cycle. Low grade heat rejected by the flue gases through the stack is used as the primary heat source, while a secondary heat exchanger utilizes th...

An adaptive genetic-simplex algorithm for parameter optimization in nuclear power plant is proposed by using adaptive crossover and mutation techniques and integrating genetic algorithm with simplex algorithm. The modified algorithm enables the handing of nonlinear constrained optimization problem because of dramatically improved search capability. Performance comparison between the proposed al...

Electric power generation system development is reviewed with special attention to plant efficiency. While higher efficiency is well understood to be economically beneficial because of fuel savings, its effect upon reduction of all plant emissions without installation of additional environmental equipment, is less well appreciated. As CO2 emission control is gaining increasing acceptance,effici...

Creep resistant alloys designed for power plant applications like thick section boiler components, steam lines, turbine rotors and turbine castings must be reliable over long periods of time in sever environments. Besides high creep strength these materials must exhibit also other properties, i.e. good corrosion and crack resistance as well as good weldability. The environmental impact and econ...
