Determine the mass flow rate fuel supplied to a boiler when the temperature of the entering water is 20 C and the exiting temperature is 89 C. The flow of.the pressured water is 2 Kg/s. There is a negligible pressure drop through this boiler and it operates at a constant pressure of 3 bars. The specific heat is c = 4,370 J/(Kg K). There is a 150000W rate of heat loss from the boiler during this process to a surrounding at 293.2 k. Consider steady state conditions. The high heating value (HHV) of the fuel is 50.02 MJ/kg. The cost of the fuel based boiler system is $5000 and has a lifetime of 20 years. The fuel cost is $0.10/kg. There is a tax charge of $0.50/kg of CO2 emission that is passed on to the user. The unit is used for 10 hours per day, 280 days per year. Calculate 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.
