Use of organic fluids in solar turbines
Abstract
The paper discusses theory and experiments on the use of a Rankine cycle engine with organic fluid vapor, where the temperature of the heat source is in the moderate range 150-300 C, in solar electric power plants. The effect of different fluid parameters on the turbine design is studied. Work on a prototype 350 kW system based on FC75 fluid, axial single-stage turbine with rotation speed of 3000 rev/min with total injection, feed temperature of 235 C, pressure ratio of 133, and 75 percent efficiency, is described.
