. American engineer . larger building. Nine of the boilers were equippedwith Green chain grate stokers, and the products of combustionwere taken care of by one brick stack 72 in. in diameter byISO ft. high, one tile stack 86 in. in diameter by 1S3 ft. high, andtwo steel stacks 6S in. in diameter by 90 ft. and 11 ft. highrespectively. All of this equipment was retained with the of the brick and steel stacks which were replaced by a216 ft. reinforced concrete chimney 10 ft. inside diameter, de-signed by the W. W. Kellogg Company, New York, and shownin Figs. 1 and 2. It was found that the draft obtained with theold stacks had not been sufficient to burn the coal economically,and this chimney will more than handle the present number ofboilers, and allow for increases in future. The 1S3 ft. tile stackhandles the products of combustion for the 3 Cahall boilers in thesecond boiler house. The handling of the coal from the cars to the boilers andthe ashes from the ash pits was done entirely by hand, and. Fig. 2—Boiler House, Showing New Concrete Chimney.* the labor cost for this work was excessive. A coal and ashhandling arrangement was therefore installed, as shown in and 6, which makes it possible to reduce this cost over SO percent. The coal is now dumped from the car directly into adepressed concrete hopper which feeds the coal automaticallyinto two elevator buckets. These buckets are alternately raisedto the top of the chute and automatically dumped into two storagebins above which a crusher is located for emergency use. Fromone of these bins it is distributed to a trolley conveyor, or hopper. he concrete cliimney replaces the bricl< chir ■ight and another steel stack, not shown, dir This photograph also shows the constructio chute. The receiving hopper and the coal iney A, the steel stack onjctly behind the new chimn of the upper part of the:rusher are plainly visible. 193 194 AMERICAN ENGINEER. Vol. S7, No. 4.
