Question:
Provide a simple payback analysis for implementing a cogeneration system in a hospital. Assume the following characteristics for the cogeneration system:
• Fuel input rate: 8,000 Btu/kWh
• Heat recovery rate: 4,800 Btu/kWh
• Maintenance cost: $0.02/kWh
• Maximum electrical output: 200 kW, 300 kW, 400 kW, 500 kW, 600 kW, 700 kW, or 800 kW
• Installed equipment cost: $700/kW, $1,000/kW, or $1,500/kW Table 9.8 summarizes the energy usage and cost of the hospital. Assume that the boiler(s) efficiency is 75 percent. The heating value of diesel fuel is 140,000 Btu/gallon. Present the results in one graph: the payback period versus the equipment cost for various equipment sizes.
