The Consequences of Compressor Operation in Overload
نویسنده
چکیده
This work describes the potential consequences associated with operating a centrifugal compressor in overload. Nomenclature is offered to explain what is meant by overload operation, and methods that are used by original equipment manufacturers (OEMs) and end users to define overload limits are presented. The paper also describes the conditions that can lead to overload operation. Computational fluid dynamics (CFD) results are used to illustrate the forces acting on an impeller when it operates at very high flow. Finally, this paper suggests considerations that should be addressed when designing (or selecting) an impeller that could be subjected to extended overload operation.

In this study, operation of compressor station has been investigated by exergy approach. Exergy analysis is a thermodynamic method which shows the irreversibility of a system quantitatively. Gas compressors are used to compensate the pressure drop along the gas pipeline significantly. The compression process causes temperature rise of gas; in this regard gas cooler is applied to reduce the temp...
متن کاملEffect of aging and manufacturing tolerances on multi-stage transonic axial compressor performance
The Axial compressor is an integrated part of a gas turbine. The central part of compressors is its blades. Blade aerodynamic has a significant effect on compressor performance. Because of the adverse pressure gradient in the compressor, any deviation in the blade profile has a significant influence on the flow field as well as the compressor performance. During the manufacturing and operation ...
