Centrifugal and Axial Compressor Control

Control engineers, mechanical engineers and mechanical technicians will learn how to select the proper control systems for axial and centrifugal compressors for proper throughput and surge control, with a particular emphasis on surge control. Readers will learn to understand the importance of transmitter speed, digital controller sample time, and control valve stroking time in helping to prevent surge. Engineers and technicians will find this book to be a highly valuable guide on compressor control schemes and the importance of mitigating costly and sometimes catastrophic surge problems. It can be used as a self-tutorial guide or in the classroom with the book’s helpful end-of-chapter questions and exercises and sections for keeping notes.

• Reviews fundamentals of both axial and centrifugal compressors, including typical operational conditions
• Concise explanation of throughput and surge control
• Useful exercises and work problems (with answers supplied) for use in the classroom or self-instruction, including sections for keeping personal notes
• Sample simulation program for surge modeling and control
