Steam power plant lab experiment

• Complete data for the Rankine Cycler experiment (Exp#5) is now posted on Beachboard. Please use it for the calculations and analysis. Explain the following information in the theory section of this report: What are the major differences between a gas turbine and a steam power plant. Compare the thermodynamic cycles of the two engines. Which engine is more efficient and why? Data collected by the data acquisition software is used to plot various graphs listed in part I. One set of data has also been selected to complete the calculations in part II. As discussed in class, the state and enthalpy at point 1 (steam leaving the boiler) must be determined using property tables, and detailed analysis and interpolations must be included in your sample calculations. The link Thermophysical Properties of Fluid Systems must be used to find the enthalpy at every point of analysis (point 1, 2, 3/4, and 5) and the entropy at point 2. These values must be presented in the following table. Note that point 5 is assumed to be saturated liquid at Patm . : Point T (oF) P (psia) state h (Btu/lbm) 1 S (Btu/lbmR) NR 2 3/4 3i NR NR 5 Saturated liqiud NR Note that these enthalpy values must be used in calculations and analysis of various components. The results of part 2 calculations must be presented in a table.

Through this study, it is possible to create plants for power generation and predict the amount of energy that can be extracted from natural resources used. Modern day thermodynamics and power plant systems are developments of work from William Rankine, a Scottish civil engineer. Rankine developed a theoretical process, known as the Rankine Cycle, which could produce electricity. Processes The Rankine Cycle includes the following four steps: 1. Water is pumped into a closed container called a boiler 2. Temperature and pressure of water is increased as it is heated in the boiler and turns into steam 3. The steam expands through a turbine where work is produced and pressure drops 4. The temperature of the exit steam is reduced, condensing it back to water, before being pumped back into the boiler Components The four major components of a steam power plant are the boiler, the turbine, the condenser, and the pump: ▪ Water is heated in the boiler, to begin the extraction of energy. ▪ The turbine converts this energy into work as the high temperature and high pressure steam that flows through, rotates the blades and shaft. Steam exits the turbine at a lower pressure. ▪ Steam enters the condenser, heat is removed allowing the steam to cool and condense back to water. The rate at which the steam is cooled depends on the coolant and method used in the condenser. ▪ Finally, the work is supplied by the pump, in order to transport the water back into the boiler,
