Periods frequently occur during the year when a plant such as the South Dakota State College power plant designed to carry a combined power and heating load will have to supply a large power load when there is a little demand for steam heat, while during other periods of the year the plant will be called upon to supply a large heating load when there is no corresponding large demand for electric power. In many plants similar to the one under consideration the power load is not sufficient and the exhaust steam from the prime mover is not adequate for supplying the proper quantity of steam to the heating system during sever winter months. This situation necessitates the supplying of live steam directly by the boiler through a reducing valve to the heating system to make up deficit.
