These valves are controlled by hand-wheelsmounted on stands in the turbine room. A separate steam mainis provided for the steam driven auxiliaries, which are all de-signed to use superheated steam. Steel pipe, with extra-heavywelded flanged joints, is used for all high pressure steam lines,contraction and expansion being provided for by the use of longradius bends. An exhaust line leads from each turbine directly down to itscondenser and is connected by an automatic relief valve to anindividual outboard exhaust line, which passes through the tur-bine room basement to the outside of the building and thence toa point above the roof.

Openings in the bottom of the flight conveyors dis-charge the coal into sprouts leading to thestoker hoppers of theboilers. The capacity of the flight conveyors is in excess of theamount of coal required to operate the boilers, and the surpluscoal is discharged at the further end of the boiler room into aconcrete storage bin below the boiler room floor. Coal received by rail is dumped from the car directly into achute leading to this same storage bin. When the boilers are tobe supplied from this source the coal is discharged from the binby gravity into a coal crusher, and from thence into a bucket con-veyor located in a tunnel underneath the bin, by which it is de-livered to the flight conveyors above
