What are the disadvantages of the organic Rankine cycle?
Additionally, ORCs eliminate the need for full-time plant operators because they operate at lower pressures and do not need water chemistry maintenance. However, working fluid cost, decomposition, temperature limits are an organic Rankine cycle's primary disadvantages.
What are the advantages and disadvantages of Rankine cycle?
Current interest in the Rankine engine stems from its potential to have low emissions and its ability (because it is an external-combustion engine) to use a variety of fuels. The disadvantages of the engine are its complexity and low efficiency.
What are the factors affecting the performance of Rankine cycle?
There are many factors affecting the Organic Rankine Cycle's (ORC) performance, such as working fluid selection, evaporator and condenser temperatures, pinch point temperature differences (the minimum temperature difference between refrigerant and the waste heat source (PPTDevap) or cooling water (PPTDcon)), ...
What are the limitations of Rankine cycle?
The efficiency of the Rankine cycle is limited by the high heat of vaporization of the working fluid. Unless the pressure and temperature reach supercritical levels in the boiler, the temperature range over which the cycle can operate is quite small.
It is a variation of the Rankine cycle named for its use of an organic, high-molecular-mass fluid (compared to water) whose vaporization temperature is lower ...
