Introduction
The objective of this project is to design a non-ideal Rankine cycle in order to supply power to a town of choice-- that being the town of New Paltz. A power plant by the Hudson river is chosen and the characteristics of the river is used in order to perform calculations, such as it’s velocity and mass flow rate. Only a percentage of the mass flow rate is required to cool the plant itself. Parametric studies are performed to observe the effects of variables such pressure, temperature, power, and efficiency in order to assure the cycle will perform well in what it is designed to do.
The Rankine cycle is an idealized heat engine cycle that estimates the the power production of vapor power plants. In the rankine cycle all turbines and pumps are isentropic. However, for the purpose of this project we will study non-ideal Rankine cycles, meaning there will be pressure variation during the processes at the boiler and condenser, and entropy variation during the processes at the pump and turbine.The four rankine cycles studied include simple, modified, modified with open feedwater heater and modified with closed feedwater heater.
The four components of the Rankine cycle are the pumps, the boilers, the condensers, and the turbines. These components are also steady flow devices, which enables the analysis of the Rankine cycle to be regarded as such.
Following the theorem of the Rankine cycle and using the equations mentioned above as a reference point, several cycles can be designed and as more complex systems.
Each of these cycles are meant to be placed in a real life situation as power plants located at a nearby town to act as its power source. Using the same values for its maximum and minimum pressures and temperatures, as well as the mass flow rate and velocity of water flow, the efficiencies and work are to be calculated. The dimensionings of the piping for the designs are also be to calculated for and their availability in the market must be accounted for.
