Electric power generation requires a great deal of production equipment, such as steam turbines, boilers, etc., how to insure the well-run condition of such equipment is the key for normal production. It is an efficient way to using computer modeling and simulation technology during the training of equipment application. First of all, build their plane model according to the equipment drawings,...

With multiple primary and secondary energy converters (diesel engines, steam turbines, waste heat recovery (WHR) and oil-fired boilers, etc.) and extensive energy networks (steam, cooling water, exhaust gases, etc.), ships may be considered as complex energy systems. Understanding and optimizing such systems requires advanced holistic energy modeling. This modeling can be done in two ways: The ...

Hydrothermal systems typically consist of hot permeable rock which contains either liquid or liquid and saturated steam within the voids. These systems vent fluids at the surface through hot springs, fumaroles, mud pools, steaming ground and geysers. They are simultaneously recharged as meteoric water percolates through the surrounding rock or through the active injection of water at various ge...

Modern economic globalization would be impossible without our ability to move billions of tonnes of raw materials and finished goods among the continents and to fly at speeds approaching the speed of sound. These realities were made possible by the interaction of economic and technical factors. Much has been written about their organizational and political underpinnings (ranging from the role o...

Scope In view of the constant growth of electricity usage and public pressure to reduce the dependence on nuclear power plants in the energy supply, solutions are sought to increase the capacity of power plants using fossil fuels. Highly efficient cycles are available : gas turbines combined with waste heat boilers and steam cycles are able to achieve efficiencies above 5055%. However building ...

The physicochemical and droplet impact dynamics of superhydrophobic carbon nanotube arrays are investigated. These superhydrophobic arrays are fabricated simply by exposing the as-grown carbon nanotube arrays to a vacuum annealing treatment at a moderate temperature. This treatment, which allows a significant removal of oxygen adsorbates, leads to a dramatic change in wettability of the arrays,...

The maintenance of industrial systems is crucial for productivity, products quality and supplied services. Numerous computer systems are therefore developed for the task and must, in most cases, collaborate with each other. In the light of this statement, our work aims at realizing a system which consists in gathering the knowledge and the know-how in the field of fault diagnosis for steam turb...

The European electricity market has been deregulated recently. This means that energy companies must optimize power generation considering the rapidly fluctuating price on the spot market. Optimisation has also become more difficult. Novel production technologies, such as gas turbines (GT), combined heat and power generation (CHP), and combined steam and gas cycles (CSG) require non-convex mode...

Journal bearings are widely used to support the rotor of industrial machinery with high loads, such as steam turbines, centrifugal pump and compressors. The problem of journal bearings can cause catastrophic failures, results in huge economic loss and create high safety risks. It is necessary to develop effective condition monitoring technologies to detect and diagnose the failures at early sta...

Energy management on the demand side is an important practice through which to address challenge of energy shortage. In Pakistan, power plants have no specific and a detail audit normally observed as one-time estimation that does not give significant information. this study, combined-cycle gas turbine station was conducted empirical data were compared with those obtained model developed in ASPE...
