THE THERMODYNAMIC ANALYSIS OF THE SZEWALSKI HIERARCHIC VAPOUR CYCLE COOPERATED WITH THE SYSTEM OF HEAT RECOVERY
Abstract
In this paper, thermodynamic analysis of the Szewalski hierarchic vapour cycle cooperated with the system of heat recovery from exhaust gases are presented. According to that purpose, the CFM (Computation Flow Mechanics [1,3]) approach has correctly been used. The whole system consists of the first traditional steam cycle, the second organic Rankine cycle (ORC) and system of heat recovery with use of water with temperature 90 oC. The Szewalski binary vapour cycle is providing steam as the working fluid in the high temperature part of the cycle, while another fluid – organic working fluid - as the working substance substituting conventional steam over the temperature range represented by the low pressure steam expansion [2,3,4]. It has been assumed that at the disposal is the theoretical rate of heat of water equal to 200 MWt from exhaust gases to use for heating low boiling point fluid. In fig. 1 the power NelRU and the reference efficiency ηre of the Szewalski hierarchic vapour cycle with and without using waste heat vs temperature of condensing water Tcon,W , the type of low boiling fluid has been presented.
