A Practical Calculation Method of Varying Pressure Steam Accumulators

Abstract

In this paper, a practical calculation for the capacity of varying pressure accumulators is developed in detail. To facilitate the calculation of the amount of self-evaporation and the fraction of steam space, two functions of pressure are introduced and are evaluated by using the JSME steam table. Approximated expressions resulting in quick and exact calculations are also given. One of the great merits of the proposed method over existing ones is that the effect of the initial steam space on the accumulator characteristics can be easily and accurately evaluated producing results that are final.
