Steam Traps-The Oft Forgotten Energy Conservation Treasure

Abstract

In these days of high technology, the steam trap is often treated as a commodity item, forgotten by many and respected by a relative few. Yet, in many facilities, widespread undetected failure of steam traps has wasted 5-15% of a plant's total steam generation. Stopping this waste represents a major energy conservation treasure characterized by low investment and a fast payback. The proper application of steam trap technology requires the experience and judgment of a dedicated champion at each location. This paper will present an overview of a working steam trap program starting with the initial survey and loss estimates. Trap characteristics and performance by generic type will be discussed with practical examples utilized to illustrate the myths in steam trap sizing and the consequences of over-sizing. Standardization of trap inventory, training and follow-up are the other key program elements addressed.
