Hubert E. Collins provides a practical guide for operating engineers who must handle steam turbines without extensive prior factory training. The text addresses the daily operational realities of power plant machinery, focusing on mechanical details rather than abstract theory.
The book begins with a thorough examination of the Curtis steam turbine, detailing foundation plans, step-bearings, and the precise methods required to measure and adjust bucket clearances. It explains how to access lower guide-bearings and inspect carbon packing rings without causing equipment damage.
Subsequent sections cover valve-gear mechanics, governors, and safety-stop devices designed to prevent overspeed. The text addresses common operational challenges, such as stage valve failures and friction in shield-plates, offering step-by-step procedures for correction.
Detailed chapters are dedicated to Allis-Chalmers and Westinghouse-Parsons turbines, examining their internal blading construction, balance pistons, and labyrinth packing. Special attention is given to the intricacies of water seals, oil circulation systems, and cooling coils.
The manual concludes with extensive procedures for testing steam consumption, evaluating condenser efficiency, and maintaining auxiliaries. It outlines the practical steps required to diagnose friction, manage vacuum levels, and prevent common mechanical failures in power plant operations.
