Boiler House Basement From B To A Station

The boiler-house basement at Wangi Power Station, photographed from the B Station end looking back toward the A Station end, runs the length of the building underneath the boiler-firing levels. The basement is a concrete-floored level with structural columns rising in regular rows. The ductwork, the ash-handling plant, and the boiler drain lines that once ran along the underside of the firing levels above have mostly been removed for salvage. What remains is the structural arrangement and the smaller-gauge piping. The lighting is bare bulbs on a perimeter circuit; daylight comes through small ground-level windows. The B Station end carries the pulverised-coal residue from the boilers above; the A Station end carries the stoker-firing residue.

The boiler-house basement was where the ash-handling plant lived: the conveyors, the pulverisers, and the hoppers that moved fly ash and bottom ash from the boilers above to the storage and transport systems outside. The plant ran continuously through the working shifts from 1958 to the closure of B Station on 31 October 1986. After equipment removal between 1995 and 1997, the basement holds the structural arrangement of an active ash-handling system, with the working plant absent.
