B Station Between Turbine Hall And Boiler House

The bay between the B Station turbine hall and the B Station boiler house at Wangi Power Station is the connecting corridor that carried the steam pipes, the feedwater lines, and the access for maintenance crews moving between the two halls. The corridor is a high steel-framed space, narrower than either of the halls it connects, with overhead crane rails running along its length. Catwalks at multiple levels cross the bay. The pipe runs that once carried the high-pressure steam from the boiler house to the turbines have mostly been removed; the supporting structural brackets remain, anchored to the column faces. Light comes from clerestory openings in the roof above.

The B Station bay between the boiler house and the turbine hall was the umbilical of the pulverised-coal half of the plant. High-pressure superheated steam ran through the steam pipes here from the three Babcock & Wilcox pulverised-coal boilers to the three 60 megawatt Parsons turbo-alternators. The corridor saw heavy maintenance traffic across the working life of B Station from 1958 to 1960 (commissioning) and 1986 (closure). After equipment removal between 1995 and 1997, the structural envelope of the corridor remains. The steam pipes are gone.
