A utility company has a feedwater heating system that has output power of 15. kw. The system has an efciency of 55%.. Find the energy consumption in W used by the existing system. ll} They are considering updating the heating system wii the same output power but with a 55% efficiency. What is the reduction in energy consumption in kw for the company if it updates the heating system? [2} The system unit will have a load factor of ESE-E. ie it will run for 3556 of the year {in economics, we have something similar called the capacity utilization rate]. Assuming 355 days in a year, calculate the annual operating hours of the system. 11} Suppose the new heating system costs $1,550 and will last for 25 years and have no salvage value. The company can sign a ZS'year contract to get fuel for the heating system at $1.05 kWh. Use the Annual Equivalent method to determine if the company should purchase the new heating system. IE} Suppose we have the same project as in part d] except that the fuel costs are $0.05 kWh in year 1 but increases g = 4% per year over the life of the fuel contract. Use the Annual Equivalent method to determine if the company should purchase the new heating system. IE}
