Everything I've read on the Rankine cycle indicates that the feedwater pump is necessary for the cycle to work. However the steam cycle used in traditional household boiler / radiator systems seems to challenge this.
The cycle for the household boiler seems to be a closed loop cycle with just a heat source (boiler) and cold source (radiators). But those two pieces are sufficient to have steam flow through the radiators, condense, and then return to the boiler.
- Is my understanding of the boiler / radiator cycle correct?
- If so, and if the system was fitted with a turbine, could it produce any amount of power?
- If it produced any amount of power, how inefficient would it be compared to a Rankine cycle?
- Is there a name for the type of cycle in a boiler / radiator system?
