Reliability‐centred maintenance applied to power plant auxiliaries

Abstract

Availability of auxiliary equipment for coal‐based power plants is very important for the achievement of maximum generation and the improvement of plant load factor (PLF). In this context a realistic maintenance programme based on plant‐specific failure data will help to achieve an optimum performance level. Reliability‐centred maintenance (RCM) is a recent technique which is limited to a few areas and has implementation difficulties. Presents a realistic RCM‐based maintenance methodology for coal‐based power plant auxiliaries. Applies the methodology to the bowl mill, an item of auxiliary equipment. Presents results and savings that have been achieved with the application of the methodology.
