background: in this study, measurement of indoor radon and its progeny levels was carried out in gas turbine power station in haryana ( india ), where natural gas is used as fuel. for comparison, the results of a study carried out in thermal power plant in haryana are also presented. radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...

Wind power is currently the fastest growing renewable energy application in the United States. Many regions, however, such as the state of Florida, do not have high enough average wind speeds for wind power to be economically feasible. Nevertheless, Florida's extensive coastline may present the opportunity for implementing offshore wind technology. Offshore winds are typically stronger due to t...

This paper develops and validates a power flow behavioral model of a gas turbine engine with a gas generator and free power turbine. “Simple” mathematical expressions to describe the engine’s power flow are derived from an understanding of basic thermodynamic and mechanical interactions taking place within the engine. The engine behavioral model presented is suitable for developing a supervisor...

As a result of their unique heat recovery properties, Humidified Gas Turbine (HGT) cycles have the potential to deliver resource-effective energy to society. The Evaporative Gas Turbine (EvGT) Consortium in Sweden has been studying these types of cycles for nearly a decade, but now stands at a crossroads, with commercial demonstration remaining. This thesis binds together several key elements f...

The integrated gasification combined cycle (IGCC) is an electrical power generation system which offers efficient generation from coal with lower effect on the environment than conventional coal power plants. However, further improvement of its efficiency and thereby lowering emissions are important tasks to achieve a more sustainable energy production. In this paper, a process simulation tool ...

This paper develops a novel data-driven fuzzy modeling strategy and predictive controller for boiler-turbine unit using fuzzy clustering and subspace identification (SID) methods. To deal with the nonlinear behavior of boiler-turbine unit, fuzzy clustering is used to provide an appropriate division of the operation region and develop the structure of the fuzzy model. Then by combining the input...

Over the last 50 years industrial gas turbines have advanced significantly. Horsepower has increased 200 percent (and even higher) within the same envelope. Improvements in efficiencies and reliability (more operating time before overhauls) are being made more often. What took 15 years to change 30 years ago, now, in the last 15 years, happens in five years or less. There are constant demands f...

Due to the serious power shortage in Taiwan, many simple cycle gas turbine generation sets (GENSETs) that were originally designated to serve as peak load units are forced to operate continuously during the entire summer season. The retrofitting projects have been seriously considered to convert these GENSETs (which have the advantage of fast startup, but suffer from low power output and therma...

Reliability analysis for Gas turbine power plant over a period of 66-month was carried out. The most important failure modes units were identified and the descriptive statistics at failure and machine level were calculated. Several theoretical distributions were applied and best fit of failure data was identified. The reliability and hazard rate models of the failure data were determined to pro...

Measurements of the flow field around a low pressure turbine blade are presented. The purpose of the experimental study is to investigate the detailed transition and separation characteristics on low pressure turbine blades. The present study focuses on the effect of Reynolds number on the formation of separation bubbles on the turbine blade surface. Specific attention is paid to the flow withi...
