B End Of Boiler House Basement

The B Station end of the boiler-house basement at Wangi Power Station closes the run of the long basement bay with a concrete bulkhead and a service stairway up to the firing level above. The basement floor at this end shows the heavier wear pattern of the pulverised-coal ash-handling system that ran here, with darker staining than the A Station end of the basement. Pipework brackets and conduit runs are still in place across the bulkhead and the side walls; the major plant has been removed. The stairway up to the firing level is steel-grating treads on a steel-frame structure, the handrail painted in the pale industrial green of the plant. Daylight comes through a small window high in the bulkhead.

The B Station end of the basement served the three 60 megawatt pulverised-coal units commissioned 1958 to 1960. The ash from the boilers above accumulated here in the bottom-ash hoppers and the fly-ash collection system before being conveyed out to the disposal area. The plant ran continuously through every shift across the operational life of B Station to closure on 31 October 1986. Equipment came out between 1995 and 1997. The basement bulkhead, the stair, and the structural framing remain.
