Abstract

Discharge of a large volume of steam from a boiler to atmosphere is a complicated and risky task. It can cause damage to equipment or even injury to personnel in the vicinity. A device was designed, based on the arrangement of a valve and vent pipe junction, such that no excessive load arising from the thermal expansion or reaction induced movement is transmitted back to the valve discharge branch, thus avoiding valve malfunction. Specimens were designed and fabricated to satisfy the actual working conditions. Both air and steam were used in the experimental works. Theoretical and experimental results were then studied on the flow phenomenon of the connection. This study leads to a design analysis of the safety valve-vent pipe. The results have shown good correlations between the theoretical and experimental results and thus lead to the prediction of valve-vent pipe sizing.
