this paper presents a new arc starter circuit that is usable in manual metal arc welding (mma) power supplies. the proposed circuit uses an auxiliary circuit and a series coupling transformer for adding high frequency spikes to output dc voltage during arc striking. the proposed circuit is usable in inverter based arc welding supplies and it could result in a decrease of weigh, volume and expen...

We present results of a life cycle assessment (LCA) of Marcellus shale gas used for power generation. The analysis employs the most extensive data set of any LCA of shale gas to date, encompassing data from actual gas production and power generation operations. Results indicate that a typical Marcellus gas life cycle yields 466 kg CO2eq/MWh (80% confidence interval: 450-567 kg CO2eq/MWh) of gre...

Introduction: Cognitive emotion regulation (CER) strategies define as cognition-based responses according to emotion-eliciting experiences that can change the type and severity of individuals’ reactions and behaviors. This modification may positively or negatively affect cognitive performance and therefore, it is a defining issue in the workplace. Notably, industries such as combined cycle powe...

With the development of Smart Grid, accurate prediction power generation is becoming an increasingly crucial task. The primary goal this research to create efficient and reliable forecasting model estimate full-load a combined-cycle plant (CCPP). dataset used in subset publicly available UCI Machine Learning Repository. It contains 9568 items data collected from CCPP during its full load operat...

Fuel consumption optimization in thermal power plants is one of the essential topics saving energy field world. Then; it necessary to review and provide solutions increase efficiency. The present manuscript has recovered heat dissipation from plant stacks. Kalina cycle was studied use exhaust gases generate Tarasht plant. Net output calculated at about 2080 kW, which increases total production ...

In order to monitor the performance and related efficiency of a combined cycle power plant (CCPP), in addition best utilization its output, it is vital predict full load electrical output. this paper, output CCPP was predicted employing practically efficient machine learning algorithms, including linear regression, ridge lasso elastic net random forest gradient boost regression. The original da...

Carbon Capture and Storage (CCS) is a recognized technology pathway to curb the increasing emissions of carbon dioxide (CO2) from the power generation sector. But most available technologies are still on the study or laboratory-scale level, so that considerable R&D efforts are needed to achieve commercialization level. The Graz Cycle originally presented in 1995 by Jericha [1] is an oxyfuel tec...

Efficient and flexible operation is essential for competitiveness in the energy market. However, CO2 emissions of conventional power plants have become an increasingly significant environmental dilemma. In this study, optimization a steam process IGCC was carried out, which improved overall performance plant. CCPP with subcritical HRSG modelled using EBSILON Professional. The numerical results ...
