Black and white photograph of the front of the No. 1 & No. 2 John Thompson boilers in the Kodak Australasia Pty Ltd Power House Boiler Hall, circa 1961. This view shows the operator station with left and right Hamworthy oil burners, the lagged recirculating oil supply lines and control valves, air supply ducting, and super-heater headers above. An operator adjusts the controls of the left hand burner on the No.2 boiler.

These boilers used cheap residual oil (commonly called bunker oil) which had relatively high ash, nitrogen and sulphur content compared with other fuel oils. Under normal temperatures bunker oil was also highly viscous and required constant heating to allow it to flow through supply lines. It also required atomising steam at the burner guns to produce a reasonable spray pattern.

This system was converted to natural gas in the 1970s.
