Question 3 A new coal supplier sent you a sample from two separate mine sites, with the ultimate analysis of the dry coal given below: Coal A (9%) 75 15 10 2 8. Coal B 77 Component H. 5 1 11 Ash How much energy is released from perfectly combusting 1kg of each coal (C and H) under standard conditions? How much air is required to burn that 1 kg? Assume that the system is operated with 40% excess air, at 35°C, 1 atm, and 70% relative humidity. (Note: the saturation pressure of water vapour at 35°C is 5.63 kPa) Based on the above analysis, what coal would you recommend? What are 3 other factors that may need to be considered for this decision? 469
