Abstract
The aim of the paper is to revalorizate of the Szewalski binary vapour
cycle by analysing thermodynamical and operational parameters of this
cycle. This was carried out by accessible numerical computational flow
mechanics codes using the step-by-step modeling of separate elements. The
binary vapour cycle is providing steam as the working fluid in the high
temperature part of the cycle, while another fluid - a low boiling point
fluid of low specific volume - as the working substance substituting
conventional steam over the temperature range represented by the low
pressure steam expansion. The steam cycle for reference conditions has
been assumed. Four working fluids in the low temperature part of the
binary cycle such as propane, isobutane, ethanol and ammonia have been
investigated.
