Introduction:
The course is devoted to design features, efficiencies, operating characteristics, reliability and maintenance implications of centrifugal compressors and steam turbine drivers.
Centrifugal Compressors play a very essential role in many petrochemical and industrial plants. Centrifugal compressors, in general, runs at very high speeds and are exposed to high temperatures. The compressor operation is confined between the Surge and Stonewall limits. The compressor performance also is affected by the variation in operating conditions. Elevated temperature and large centrifugal stresses make the gas turbine operating under very critical conditions require very complicated monitoring and protection systems. Accurate instrumentation, monitoring, troubleshooting and maintenance programs are essential for maintaining and increasing the available time of the machines. Understanding and learning Centrifugal compressors more deeply help smooth and free trouble operation.
