COAL-HANDLING APPARATUS Coal delivered at the power stations on cars is dumped fromthe cars into pockets, from which it is delivered by suspendedflight scraper conveyors into the hoppers of crushers, where itis reduced to the proper size for handling with the mechanicalstokers. From the crushers it passes into a pocket conveyor,which lifts it to the top of the building and delivers it to longi-tudinal conveyors of the suspended flight scraper type, whichdump it into the coal bunkers over the boiler room. Fromthe bunkers it is delivered through vertical down-spouts toRoney mechanical stokers, operated by steam. The ashes drop from the grates into hoppers, from whichthey are collected in push cars of i-ton capacity running in anash tunnel in the boiler room basement. These cars are dumpedinto a hopper, from which the ashes are lifted by means of a

Cars on the trestle arespotted by means of an electric winch. Coal delivered by boatis hoisted in a clamshell bucket of i-ton capacity, operated bya steam hoist. The coal-handling capacity is 80 tons per hourand the ash-handling capacity is 25 tons per hour. The maxi-mum coal consumption at the power stations will be about 220tons per day. Aside from the hoist for unloading coal from boats, whichis operated by steam, the coal-handling apparatus is all drivenby electric motors. The conveyors are driven by 220-voltthree-phase induction motors, varying in capacity from 7J/2 hpfor the ash conveyor to 40 hp for the coal crusher and con-veyors.
