An economic justification of using a small turbine rather than pressure reducing valves between the high pressure header and high pressure heating lines of V.P.I. Power Plant

Abstract

Generally it is believed that in a power station when there is a demand for process steam and also demand for heating, most of the auxiliaries of the plant should be arranged to be driven by steam rather than using electrical energy for them. This is, however, a general remark and a correct selection can be made only after a detailed study is made of all factors involved. The V. P. I. central heating and power plant works mainly as a heating station, generation of electrical energy, being a by-product. So this problem is completely different from the standpoint of a general power station. This station supplies heating steam to the college through two different pressure lines. One is the low pressure, and the other is the high pressure line.
