While utility experience with Terry turbines has been positive, controls and adjustments of controls have required frequent attention. This technical guide addresses the Terry turbine controls, such as trip system, throttle valve linkage and governors. This guide will familiarize personnel who have not had prior experience with the design, organization and setup of these control systems. This document provides instructions for a broad range of utility personnel on optimum methods for the repair, maintenance, adjustment, and troubleshooting of the Terry turbine controls. The guide includes an engineering description of the operation and prevalent failure mechanisms, preventive and predictive maintenance suggestions, repair and adjustment methods, and spare parts recommendations. This guide will be a standalone updated reference manual. It will include drawings and descriptions affecting all required maintenance on the control system, and does not cover site specific appurtenances. Included are both generic and specific recommendations for utility maintenance engineers and technicians. These recommendations will help implement an effective maintenance or upgrade program for Terry turbine controls. This guide is a valuable resource for operating history and common control related problems. The preparation of this manual included the review of the applicable INPO Standby Turbine-Driven Pump Operating Experience Compilation. Individual utilities can use this guide to review their specific maintenance practices and develop improved procedures where applicable. The guide can also be used by some utilities to upgrade their Terry turbine control system. The guide is applicable to the nuclear industry and any other industry utilizing the Terry turbine models included in the document.
