121. No 2 Turbine Set.
The trubine is in place – the curved casing at the back, the steam control valve stand to its left. The open casing is for the reduction gearing, 3600 rpm to 428 rpm, to drive the generator (DC 400V) which would be installed on the cast bed frame centre. The gear casing has DBS – David Brown and Sons of Huddersfield, cast on it. In front of the genrator an extension drive shaft to a further reduction gearbox to reduce the speed to 150 rpm for the main shaft. The main shaft would pass through the sqaure hole in the wall, just visible top left, to the white beaterfloor basement. To the extreme left is visible a gear, probably part of the no 1 turbine set reduction gear to the main shaft. The turbines and generators stood side by side but the final drives to the main shaft were offset, see drawing AX107.
