A direct-fired dryer burns a fuel oil with a lower heating value of 19,000(Btu/(Ibm)' [Products of combustion are CO₂(g) and H₂0(g).] The composition of the oil is 85% carbon, 12% hydrogen, 2% nitrogen, and 1% water by weight. The flue gases leave the dryer at 450(°F), and a partial analysis shows that they contain 3% mol CO2 and 11.8% mol CO on a dry basis. The fuel, air, and material being dried enter the dryer at 77(°F). If the entering air is saturated with water and if 40% of the net heating value of the oil is allowed for heat losses (including the sensible heat carried out with the dried product), how much water is evaporated in the dryer per (Ibm) of oil burned?
