On this basis, obtained were a rapid model building method for determining the mass and energy balance of the double reheat supercritical unit as well as a method for the linear analysis of vario.

Study of circulation heat calculating model for thermal system in supercritical pressure power unit with second reheat cycles;

In this paper the authors developed the heat economy calculating model of thermal system in supercritical pressure power unit with second reheat cycles by mathematical derivation strictly,used for calculation of both unit new steam making power and circulation heat,based on the normal energy balance method and basic theory of equivalent heat drop.
