Please show system sketches and related energy flows for all problems. Solve the following: The utility providing the electricity to the boiler in problem 1.1 uses the same fuel as that used in problem 1.4 and has an efficiency of 0.35. The cost of the electric boiler is, $3,000 with a 15 year lifetime. The cost of the fuel based boiler system is $5000 and has a lifetime of 20 years. The fuel cost is $0.10/kg and the cost of electricity is $0.20/kWh. There is a tax charge of $0.50/kg of CO2 emission that is passed on to the user whether the utility based electrical system or gas fired system is used. The unit is used for 10 hours per day, 280 days per year. Which process would you recommend in terms of fuel consumption, exergy production, carbon dioxide emission and theroeconomic cost? There is no cost associated with the water input. Note the total amount of fuel consumed is directly related to the carbon dioxide emission from each process.
