What is the function of the boiler in the Rankine cycle?

• A. To cool the working fluid
• B. To burn fuel for energy
• C. To add heat to the working fluid
• D. To compress the refrigerant

Answer: (C)

The function of the boiler in the Rankine cycle is to add heat to the working fluid. In this thermodynamic cycle, the main objective is to convert thermal energy into mechanical energy, typically for electricity generation or industrial processes. The boiler serves to heat the working fluid, often water, using combustion of fuel or another heat source. As the working fluid absorbs heat in the boiler, it transforms from liquid to vapor. This phase change is crucial as it allows the vapor to expand and do work in the turbine of the cycle. The addition of heat is what drives the cycle forward, allowing the system to capture energy and produce useful work.
