The study seeks to show how online remote condition monitoring helps to improve the maintenance system in a power plant from mainly predetermined and corrective approach to predictive maintenance and, the resultant benefits of its adoption. The findings clearly indicate the various aspects of online remote condition monitoring system which thermal power plants can consider to improve on plant s...

by developing the level of life in societies, the need for new resources of energy becomes more important. in almost all cases, the aim is to convert one form of energy to the electrical form. with advances of technology and use of new electric and electronic devices and gadgets, the need for electrical energy is increasing and providing stable and continuous electric power becomes very importa...

In recent years, due to the fact that non-renewable energies come to an end, renewable energy is expected to provide a significant part of the future needs of Iran. Among these energies, solar energy is a suitable option for a wide range of the country, due to availability, proper radiation intensity, and high sunshine times during the year (about 300 sunny days per year). The purpose of this p...

fossil fuel power plant is one of the most important sources of environmental pollution of the vanadium toxic metal. this survey showed that the penicilium austuranium is the best microorganism for biosorption of vanadium isolated from environment of fossil fuel power plant. to determine the optimum ph and most biosorption and accumulation of vanadium by these fungi, power plants wastewater, pa...

There are presently four driver technologies that are being developed for IFE Power Plants: these are HIF (Heavy Ion Fusion), KrF (Krypton Fluoride laser), DPSSL (Diode-Pumped Solid-State Laser), and Z-Pinches. All four types were included in the discussions at the Snowmass Fusion Summer Study in 1999 [1]. The purpose of this paper is to discuss (1) the z-pinch power plant concept, and (2) the ...

in recent years, wind energy has a remarkable growth in the world, but one of the important problems of power generated from wind is its uncertainty and corresponding power. for solving this problem, some approaches have been presented. recently, the artificial neural networks (ann) as a heuristic method has more applications for this propose. in this paper, short-term (1 hour) and mid-term (24...
