The flues consist of straight pipes, the uptakes beingthree feet long and extending into the bottoms of the are rectangular and are placed over the rear of each rowof boilers. They pass out through the north wall to two stacks, 11 feet in diameter and 200 feet high. Thebreechings and stacks are large enough for the contemplated ex-tension of the boiler room. The breechings measure 14-6 x 9where they pass through the wall. The boilers are equipped with Green chain grate stokersand are supplied with coal from the overhead bunkers. The stokersare driven by two direct current motors, located in the transversepassage way, either of which is of sufficient capacity to carry. -13. the load should one be out of order. Under each boiler is a fineocoal hopper, at the front, and an ash hopper at the rear. In thebasement is a track that passes under these hoppers and overthe ash and coal pits so that a small motor operated hopper carcan carry the contents of them to their respective pits. Thetrack is laid to a 2,-6-3/4 gage and is of 6© pound rails. Thecar is of steel with a hopper bottom and is operated by a 125-5 3. - The Coal Handling Apparatus. All of the coal for this plant is hauled over the linesof the company and is placed on the siding at the north of thebuilding. The overhead crane is provided with a clam shellbucket which can be used to place the coal directly in the bunkersover the boilers, or the cars may be dumped to the pit below andplaced in the bunkers as needed. This crane and bucket are alsoused to remove the ashes from the
