Step by step
Solved in 2 steps
- 1. Who has invented the first internal combustion engine vehicle? when?When a hydrocarbon fuel is burned, almost all of the carbon in the fuel burns completely to form CO2 (carbon dioxide), which is the principal gas causing the greenhouse effect and thus global climate change.A new coal-fired power plant with a heat rate of 9000 Btu/kWh burns coalwith an energy content of 24,000 kJ/kg. The coal content includes 62%carbon, 2% sulfur and 10% unburnable minerals called ash.a. Knowing that 1 Btu/kWh is equivalent with 1.055 kJ/kWh, what willbe the carbon emission rate (g C/kWh)?b. What will be the uncontrolled sulfur emission rate (g S/kWh)?c. If 70% of the ash is released from the stack (called fly ash), what wouldbe the corresponding uncontrolled emission rate (g fly ash/kWh)?d. Since the Clean Air Act restricts SO2 emissions to 130 g of sulfur per106 kJ of heat into the plant, what removal efficiency does thecorresponding equipment need to have for the plant? What is the name ofthis equipment? (1 kWh = 3600 kJ)e. What efficiency does the removal equipment need to have to meet theClean Air Act standard of no more than 13 g of fly ash per 106 kJ of heatinput? What is the name of this equipment?f. If 80% of thermal losses are taken away by cooling system…
- The heating value of the a dry fuel is 18 MJ/kg. a) Calculate the effective heating value of a fuel with 40% moisture and no flue gas condensation. b) Calculate the heating value of a fuel with 40% moisture and flue gas condensation Evaporation enthalpy H=2257 kJ/kg. Cp=4,2 ( kJ/kg,K) The heating value of a moist fuel is given by this formula: H=H0*(1-f)-f*2,6 (MJ/kg), H0=heating value of dry fuel, f=fraction of water.What are the safety on Solid fuels?Why is humans are very dependent on the used of fuels to produce power?
- Answer the following question 1. What is solid fuel? 2. Give at least 6 examples of solid fuels 3. Identify and classify each solid fuels 4. What is the advantage and disadvantage of solid fuel?What are the important operational performance parameters in design of fuel firing equipment?INTERNAL COMBUSTION.
