Rankine cycle. 7.6. Rankine cycle. We are going to overview the principle of thermodynamic cycle operation using Rankine cycle example, since most of solar power cycles currently operating are Rankine cycles. The Rankine cycle system consists of a pump, boiler, turbine, and condenser. The pump delivers liquid water to the boiler.

2015/5/5 · Two types of AVT are; i) AVT (R) Using Ammonia (NH3) and as reducing agent like Hydrazine (N 2 H 4 ), ii) AVT (O) same as AVT ® minus reducing agent i.e. N 2 H 4. Ammonia is commonly used cheaper material to maintain pH in boiler water. N 2 H 4 is used to scavenge Dissolved Oxygen and protect Copper alloys from Ammonia.
