Question
The supplier told you that the data sheet used for the analysis of the coal got lost during the transport but he remembers that it contains 70.1% carbon, 6.9% moisture and 8% ash. He is also sure that the N and S content of the coal is negligible. You then instruct your subordinates to introduce the coal in the boiler together with air. The air you use for combustion is assumed to be dry at 75°F. Upon taking a sample of the stack gas, you measured its conditions to be at 850°F and 745 mmHg. The equipment you make use of for the stack gas analysis gave you 11.2%CO2, 0.7%CO and 8.3% O2.
a. You were asked by your supervisor to make the data sheet for the coal used in the boiler. You need to know the ratio of the H to be burned with the carbon, the percentage of this H in the coal, and the complete ultimate analysis of the coal.
