Maintenance practices for steam turbine control fire resistant fluids: Part 2

Abstract

This paper presents long‐term trends (over 10–20 years) of critical fluid properties from two different types of steam turbines, with the focus on the responses of applied corrective actions to maintain the fluid within manufacturer's specifications. In addition, ion exchange purification treatment is discussed, together with a simplified model to predict the maintenance cost of this treatment. Copyright © 2006 John Wiley & Sons, Ltd.

The origin, measurement and control of fine particles in non‐aqueous hydraulic fluids and their effect on fluid and system performance

“…The steady darkening of fluid colour, the development of a burnt odour and the formation of black particles in any deposit would be highly suggestive of dieseling in the system. 11,21 Particle sizes of 0.1-0.45 μm have been shown to be present as a result, and while the focus has been on the presence of carbon, varnish precursors are also likely to be found, particularly under less extreme conditions. Significant amounts of carbon (as soot) have been found in systems that have been dieseling for long periods (see the succeeding text).…”
