An exciting and urgent engineering challenge in the decades immediately ahead is to responsibly meet our national power needs. The challenge has its roots in the declining economically recoverable supplies of nonrenewable energy resources, the effects of global climate change, and the burgeoning population [1]. The aim of the project is to develop an effective power plant that satisfies given design considerations. Figure 1 Coal-fired Power Station, Poland [2] Design Considerations Choose one of the following plants for your design: Plant 1 (A 15 MW coal-fired Powerplant with topping and bottoming cycles) 1. Your power plant is supplied by coal taken from Soma, Manisa. The heating value of the coal is 3348 kcal/kg. 2. For safety issues and operation conditions, the maximum pressure of the plant and maximum temperature cannot exceed 20 MPa and 600C, respectively. 3. In the topping vapor power cycle, you have to use at least one reheat, one open feedwater heater, and one closed feedwater heater. The minimum pressure of the plant cannot be lower than 0.1MPa. 4. In addition, you need to add bottoming cycle working with Refrigerant 134-a in your vapor power cycle. In that cycle, the maximum pressure cannot exceed 1.2 MPa and the lowest pressure is 0.1MPa. 5. In your design approach, you have to consider isentropic efficiencies for the turbines and pumps. Take this value as 0.85.
