The Mechanical Handling and Storing of Material

COAL, COKE, AND ASH HANDLING PLANTS 635 Electric Light and Power Station, Brooklyn, U.S.A.—A longitudinal section of this installation is shown in Fig. 888. Here again the coal store is above the boilers. The coal is received by water, and is hoisted from the barge to a height of 125 ft. by a grab. It is then broken to about the size of road metal, after which operation it is weighed, then removed to the store by the “Hunt” automatic railway. There is an outlet from the coal bunker over each boiler. Coal-handling Plant at the United Tramway Power Station, Dublin.— Fig. 886. Coaling Plant at Eastern Station. Brooklyn Heights Railroad Co. This plant is illustrated in Fig. 889. The coal is taken from the barges by means of a grab, and delivered into weighing machines; after weighing it is passed through a coal- breaker, which reduces it to a size not exceeding 2j in. cube. There are two coal stores, the first of which is filled by Hunt’s automatic railway, while the coal store over the boilers is fed by an ordinary gravity bucket conveyor from the first-mentioned store. The ashes from the boilers are lifted by the same conveyor and deposited m a bin as shown, and from this point they can be disposed of by means of a spout. The boilers are fed by automatic stokers, each of which is fitted with an automatic weighing machine to keep a record of the coal consumed.
