Thermal Energy Loss in the Steam Valves and its Effects

Galip Temir and Durriye Bilge

Abstract

In this study, the effects of thermal losses in steam valves for flow have been analyzed. In a set of experiment built to achieve this, pressure and condensate values have been calculated in different temperatures for insulated and non-insulated cases in three different nominal diameter steam valves. The amount of energy lost from the valve surface in the natural convection conditions has been calculated through application and use of principles of heat transfer and fluid mechanics and equations of mass and energy conservation. Thermal loss coefficient change and the amount of the heat transferred from surface in 150°C steam temperature for different steam velocities have been presented in diagrams. Heat losses have been calculated in two different steam velocities in the cases of five different steam temperatures and their diagrams have been arranged.
