The fuel is elevated toa sufficient height to permit the use of gravity inhandling the coal in the remaining steps toward thestokers. From the discharge of the bucket elevator thecoal is spouted through a bifurcated outlet to a suspen-sion type bunker of 150 tons capacity. From the bunkerthe fuel falls through three S-A rack-and-pinion slidegates operated from the boiler room floor by handchains. A powerful leverage is secured by the use ofthe rack and pinion design, and this, combined withthe fact that the gate cuts into the fuel at right anglesto the flow, makes operation unusually easy. The connecting link between the storage bunker andthe stokers is an S-A traveling weigh hopper. This. HOLYOKE POWER PLANT—FIRING AISLE IN BOILER ROOM ; STOKERS, WITH ONE OF THE DUPLICATE STOKER ENGINES AND ONE OF THE DUPLICATE STEAM TURBINE BLOWERS FOR FORCED-DRAFT SYSTEM 1192 ELECTRIC RAILWAY JOURNAL [Vol. XLVIII, No. 24 •device serves to provide accurate operating records aswell as to distribute the fuel. Thus the storage bunkerdid not require extending the length of the boiler room,being conveniently located so as to be filled by a singleelevator and gravity chutes. In operation the desired stack and economizer are designed for a maximumboiler rating of 3000 hp. An air supply of 50,000 cu. ft. per minute for thefurnaces is provided by two Sirocco blower sets, eachdirect driven by a 136-hp. Terry steam turbine running
