<p>A compound engine type power plant with high thermal efficiency and high power output including a compressor (10), a positive displacement combustor (12) for adding heat to a compressed working fluid at constant volume, and an expander (14, 16). The expander is a two stage expander employing a positive displacement expander (14) as the first stage and a turbine (16) as the second stage. Heat may be added to increase the temperature of the working medium at the combustor (12) to a level well in excess of that which could be tolerated by a turbine type expander alone to thereby increase operational efficiency and power output.</p> |
