Pressure and Temperature Vessel Bench

Description of Pressure and Temperature Steam Bench:

Pressure and Temperature Steam Bench consists of a sturdy framework and panels of all steel construction, fitted with a student work surface, interconnecting back panel and adjustable feet. The steam bench includes a 2- pen chart recorder to provide a continuous recording of the process variables, namely temperature and pressure and gives students the opportunity to become familiar with the presentation of such data on a typical process recorder used in industry.

Experimental Capability of Pressure and Temperature Steam Bench:  

1. To investigate the relationship between the temperature and pressure of saturated steam  
2. To compare the experimental observations with published data such as in steam tables

Specification of Pressure and Temperature Steam Bench:   

The bench is to comprise of a mild steel pressure vessel welded in accordance with designed for a working pressure of 10.34 bar and a maximum steam temperature of 235°C and fitted with a type K thermocouple driving a 0-250°C analogue temperature indicator, a pressure measuring point coupled to a 0-16 bar Bourdon type pressure gauge, a 0-250°C mercury in steel type V temperature sensor and a pressure measuring point coupled to a circular mechanically driven 2-pen chart recorder and a blowdown line complete with a combined isolating and control valve connected to the bench blowdown line. Steam supply to the pressure vessel is to be from a fully insulated steam header with supply branch fitted with a combined isolating and control valve. The forgoing are to be installed on a sturdy frame and panels of all steel construction complete with service facilities relating to water supply, blowdown and drainage.
