A. the analysis of a woody biomass from california is reported as follows (wt. %)

moisture 38.6%

volatile matter 80.9%

fixed carbon 18.3%

ash 0.8%

carbon 50.7%

hydrogen 5.7%

sulfur 0.09%

oxygen 42.94%

nitrogen 0.57%

calculate the "as received", "dry", "dry-ash-free" proximate and ultimate analysis. (20 points)

b. the analysis of a coal is reported as follows (wt. %)

moisture 2.8%

volatile matter 26.8%

fixed carbon 66.1%

ash 4.3%

carbon 82.0%

hydrogen 5.1%

sulfur 0.8%

oxygen 6.0%

nitrogen 1.2%

hhv 14,430 btu/lb (as received)

a) calculate "dry ash-free" proximate and ultimate analyses (10 points)

b) determine the astm rank of the coal (10 points)

c)calculate the lower heating value of the coal (10 points)

d) estimate the calorific or heating value using dulong formula. what is the percent difference from the measured value? (10 points)
