 Unlike many gasworks sites in Australia that were either demolished or stripped after closure, the vertical retort house in Launceston still retained most of its original machinery after it was abandoned.Both the electric coke extractor eccentric and conveyor drive remained intact within the building along with most of the fourth floor machinery.The waste heat boiler on sublevel 3 had been reduced in size due to salvage operations in the 1980s as with the waste heat boiler on the first floor (ground level) which was also partially dismantled.
