48 UNIVERSITY OF ILLINOIS. [Dee.8y University of Michigan.—A. cut of the boiler house and chimney is shown on page eight of this report. The floor of the boiler room is about 13 feet below grade. The tunnels are quite extensive, making a complete circuit of the rectangular campus. The tunnel runs under nearly all the buildings heated, and advantage is taken of any heat radiated from the pipes by letting it intothe basement of the buildings. No stokers are used. The chimney is a handsome one. The part of the building extending to the left is the lighting plant. . They have not, however, installed in it any generators, but will ask for money for this lighting machinery from the coming legislature. There are engines in different buildings now running from the high pressure mains in the tunnels. This feature they consider bad and hope to avoid as soon as possible. Ohio State University.— This plant is still in progress of construction and was perhaps the most instructive, of any plant inspected. Their boiler house is 55x100; their engine house is 40x60, with a sub-basement, 8 feet clear headroom. This basement is cemented and serves as a store house and place for condensers and transformers. Their coal handling machinery, which has recently been installed, was the most perfect arrangement seen. It operated with much less noise and with but very little dust. Their ash conveyor runs the entire length of their boiler house, and the ashes are automatically delivered into a hopper from which they can be drawn into a wagon. They have installed in their boiler house three types of mechanical stokers, the Murphy, the Acme, and the Babeock & Wilcox chain grate. They evaporate 812 pounds of water per pound of coal, using nut and pea sizes. The smoke issuing from their chimney was very, slight. Their piping arrangements and small details were the most perfect of any which we saw, and when their plant is completed it will be a model plant. Their plan of operation is to generate electricity in their engine, house and distribute it for power and lighting purposes. They have already installed eleven (11) two-phase motors aggregating 160 H. P. These operate the fans for ventilation in the several buildings where that system is employed, as well as the different departments of their shop practice work. The wires are all carried to the buildings through the tunnels. They have in course of construction three new buildings, and have just completed 1,100 feet of new tunnel,-using paving brick for its construction, it being somewhat, larger, and, according to their. experience, more satisfactory. , NEEDS OF THE UNIVERSITY OF ILLINOIS RELATING TO NEW CENTRAL HEATING:, LIGHTING, AND POWER PLANT.. Our present heating, plant has been the result of continually adding to a plant originally designed for heating two, buildings. The boiler house is only 30x75, and the operations of firing, cleaning, and repairs are often carried on with much difficulty and loss of time. Our boilers are not working efficiently for want of a properdraft; our chimney is a continually smoking nuisance; and our boiler house is so situated that the usual direction of the smoke is over and into our buildings. A large part of the water of condensation is not returned to our b; iler house, involving increased fuel consumption for heating new w iter, as well as subjecting our boilers to increased scale formation. Upon the completion of bur Library Hall we can not furnish sufficient steam for heating it. Neither can we set additional boilers in our present house or connect them $0 our now over-crowded chimney. We are also operating three small boilers at the shops situated at the i^ther side of our eainpus, so that,it is always smoky. . ' ',..,..,''''.. ' Under the conditions existing it seems very desirable to make a radical change in our entire plant, and reorganize on an entirely new basis. The following plan is suggested as a basis upon-which to work: 1. Change location of our two present plants, tto the lowest point on our campus, i. e., between Engineering Hail and the Machinery Building.'
