15.4 Fuel Modeling 601 equation, since it results from the oxidation of the hydrogen in the fuel. For convenience, we write the combustion reaction for 100. moles of dry product formed by burning 1.00 mole of the fuel model C n H m . Using the given combustion analysis, we have C n H m + a½O 2 + 3:76ðN 2 ÞŠ ! 7:10ðCO 2 Þ + 0:800ðCOÞ + 9:90ðO 2 Þ + bðH 2 OÞ + 82:2ðN 2 Þ The element balances are Carbon (C) balance: n = 7.10 + 0.800 = 7.90 Hydrogen (H) balance: m = 2b Nitrogen (N 2 ) balance: 3:76a = 82:2, or a = 82:2/3:76 = 21:9 Oxygen (O 2 ) balance: a = 21:9 = 7:10 + 0:800/2 + 9:90 + b/2, or b = 9:00: Then, from the preceding hydrogen balance, m = 2b = 18:0: Consequently, the fuel model is C 7.90 H 18.0 , which is approximately octane, C 8 H 18 . The final reaction equation is C 7:90 H 18:0 + 21:9½O 2 + 3:76ðN 2 ÞŠ ! 7:10ðCO 2 Þ + 0:800ðCOÞ + 9:90ðO 2 Þ + 9:00ðH 2 OÞ + 82:2ðN 2 Þ b. On a molar basis, 1.00 mole of fuel contains 7.90 moles of C and 18.0 moles of H, and on a molar percentage basis, this becomes [7.90/(7.90 + 18.0)](100.) = 31.0% C and [18.0/(7.90 + 18.0)](100) = 69.0% H. The molecular mass of the fuel in this model is and so the fuel’s composition on a mass basis is and M fuel = 7:90ð12Þ + 18:0ð1Þ = 113 kg/kgmole = 113 lbm/lbmole ð7:90 kgmole C/kgmole fuelÞð12:0 kg C/kgmole CÞ/ ð113 kg fuel/kgmole fuelÞ = 0:840 kg C/kg fuel = 0:840 lbm C/lbm fuel ð9:00Þð2:016Þ/113 = 0:161 kg H/kg fuel = 0:161 lbm H/lbm fuel Therefore, the fuel can be said to consist of 31% carbon and 69% hydrogen on a molar basis or 84% carbon and 16% hydrogen on a mass basis. c. Referring to the final combustion equation determined in part a, the air/fuel ratio on a molar basis is ðA/FÞ molar = n air 21:9 × ð1 + 3:76Þ moles of air = = 104 moles air/mole fuel n fuel 1 mole of fuel and on a mass basis it is 28:97 kg air/kgmole air ðA/FÞ mass = ð104 kgmole air/kgmole fuelÞ× 113 kg fuel/kgmole fuel = 26:7 kg air/kg fuel = 26:7 lbm air/lbm fuel d. To determine the percent of theoretical air used, we must first determine the minimum air required for complete combustion. The reaction for 100.% theoretical air has the form C 7:90 H 18:0 + a½O 2 + 3:76ðN 2 ÞŠ ! bðCO 2 Þ + cðH 2 OÞ + dðN 2 Þ The element balances are Carbon (C) balance: 7.90 = b Hydrogen (H) balance: 18.0 = 2c, orc = 11.0 Oxygen (O 2 ) balance: a = b + c/2 = 7:90 + 9:00/2 = 12:4 Nitrogen (N 2 )balance:3:76a = d = 3:76ð12:4Þ = 46:6 Then the theoretical molar air/fuel ratio (for 100% theoretical air) is 12:4ð1 + 3:76Þ ðA/FÞ molar = = 59:0 mole air/mole fuel 1 theoretical finally, the percent of theoretical air used in the actual combustion process is " , # % of theoretical air = ðA/FÞ molar actual ðA/FÞ molar theoretical or 77.0% excess air. = 104/59:0 ð100Þ = 177% × 100 (Continued )
602 CHAPTER 15: Chemical Thermodynamics EXAMPLE 15.3 (Continued) Exercises 7. Determine the hydrocarbon fuel model in Example 15.3 if the CO and O 2 concentrations are both 0.00%, and the CO 2 and N 2 concentrations are 17.0% and 83.0%, respectively, in the Orsat analysis. Answer: Hydrocarbon fuel model = C 17 H 20.3 . 8. Determine the molar and mass air/fuel ratios in Example 15.3 if the CO and O 2 concentrations are both 0.00%, and the CO 2 and N 2 concentrations are 17.0% and 83.0%, respectively, in the Orsat analysis. Answer: A/F = 10.15 kgmole air/ kgmole fuel = 1.31 kg air/kg fuel. 9. If the CO concentration in Example 15.3 is 0.00% and the N 2 concentration is 83.0%, with all the other concentrations unchanged, determine the hydrocarbon fuel model and % of excess air used in the combustion process. Answer: Hydrocarbon fuel model = C 7.1 H 22.28 and % of excess air = 74.2%. In the previous example, we assume that nearly all the water produced by the combustion process condensed out by the time the combustion products cooled to 20.0°C. For this to be a valid assumption, the dew point of the combustion products must be at 20.0°C or higher. The determination of the dew point temperature for this reaction is illustrated in the next example. EXAMPLE 15.4 Determine the dew point temperature of the combustion products given in Example 15.3 if the total pressure of the mixture is 14.7 psia. Solution From Eq. (12.23) of Chapter 12, the volume fractions, mole fractions, and partial pressure ratios are all equal for a mixture of ideal gases. Exhaust products at atmospheric pressure are sufficiently ideal to allow us to determine the water vapor partial pressure at its condensation temperature (i.e., dew point) from this relation. The total number of moles of product, from part a of Example 15.3, is 109 moles. Then, using Eq. (12.23) wherein p m is the total pressure of the mixture gives π H2O = p H2O/p m = ψ H2O = χ H2O = 9:00 109 = 0:0826 where π is the partial pressure ratio, ψ is the volume fraction, and χ is the mole fraction. So, p H2O = 0:0826ð14:7Þ = 1:21 psia The saturation temperature of water vapor at this pressure is defined to be the dew point temperature. By interpolation in Table C.1a in Thermodynamic Tables to accompany Modern Engineering Thermodynamics, we find that T sat ð1:21 psiaÞ = T DP = 108°F = 42:3°C Thus, the exhaust products must be cooled to 108°F ð42:3°CÞ or below to condense the water of combustion and have an essentially dry exhaust gas. Exercises 10. Determine the partial pressure of the water vapor in Example 15.4 if the mixture total pressure is 0.150 MPa. Answer: p H2O= 12.4 kPa. 11. If the dew point temperature in Example 15.4 is 212°F, what is the mixture total pressure? Answer: p m = 178 psia. 12. Determine the partial pressure and dew point temperature of the water vapor present in the 100.% theoretical air combustion process given in part d of Example 15.3. Assume the mixture total pressure is 14.7 psia. Answer: p H2O = 2.08 psia, T DP = 128°F. WHY DO AUTOMOBILE EXHAUST SYSTEMS RUST? Water condenses in an automobile’s exhaust system and drips out the tailpipe until the entire exhaust system has been heated above the dew point temperature by the exhaust gases. This water promotes corrosion and causes the exhaust system to rust out sooner if the vehicle is used for short trips than trips long enough (a half hour or more) to dry out the exhaust system.
