Description of Lagging Efficiency Steam Bench:
Lagging Efficiency 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 incorporates four similar mild steel tubes, each connected to a common steam supply via an inlet regulating valve and a common blowdown line via an outlet valve. Two of the tubes are unlagged but have differing finishes, namely a painted finish and a chromium plated finish respectively. The remaining two tubes are lagged, one with glass fibre webbing tape and the other with a pre-formed fibre glass insulation jacket. Each tube is fitted with a sight glass and scale to enable condensate to be measured. The measured temperatures are displayed on an analogue temperature meter via a selection switch. From measurements of temperature and condensate levels over a period of time, students are able to calculate the lagging efficiency and the coefficient of thermal conductivity of the lagging.
