A new thermodynamical cycle characterised from an isothermal expansion has been examined from a theoretical point of view. In the real cycle the isothermal expansion could be approached by means of mixing re-heatings. The high temperature steam for mixing is produced in a direct steam generator burning a stoichiometric mixture of hydrogen and oxygen.

Abstract

A new thermodynamical cycle characterised from an isothermal expansion has been examined from a theoretical point of view. In the real cycle the isothermal expansion could be approached by means of mixing re-heatings. The high temperature steam for mixing is produced in a direct steam generator burning a stoichiometric mixture of hydrogen and oxygen. The theoretical analysis has shown that the reference cycle allows an efficiency very close to the efficiency of a Carnot cycle evolving between the same extreme temperatures. The ratio between the two efficiencies can approach 90%.
