screw compressors are used to produce the compressed air in the refineries. because of the frequent failures and high prices of these compressors, this research was done to determine the failure causes in one of these compressors. in this study and after about 603 working hours , female rotor compressor had been fractured. metallurgical and other experiments showed that the defect in cooling wa...

A rising number of industrial companies are aiming to increase the share renewable generation in their electricity consumption, order decrease costs or fulfill portfolio requirements. This can be achieved by using pv wind systems, which directly connected consumer. The volatility balanced employing an storage system. paper presents MILP optimization model for direct supply consumer a farm, coup...

At present time, the SE applied to solar dish reflectors is not competitive compared other concentrated power technologies because Stirling CSP equipment has complex and expensive engines does have a proper energy storage system. This paper introduces technology, proposes layout of simple with compressed air system, examines total performance equipment.
