9. Coal fired in a furnace analyzes 30% VCM, 51% FC, 14% ash, 5% M, 1.6% N and 1.2% S with a GCV of 30.1 MJ/kg. Residue analysis shows 30% FC, 15% VCM, 40% ash and 15% H.0 . Air supplied is 50% in excess and is saturated at 25 °C, 740 mm Hg. Molar ratio of Co, to CO is 5:1 and H, to CO is 1:1. The stack gas leaves at 300 °C and 765 mm Hg. Calculate: a) orsat analysis of the stack gas (7.97% CO2 , 1.59% CO, 1.59% H2 , 11.15% O2 , b) m³ stack gas/ m³ air ,77.69% N2 ) (1.93)

Transcribed Image Text:9. Coal fired in a furnace analyzes 30% VCM, 51% FC, 14% ash, 5% M, 1.6% N and 1.2% S
with a GCV of 30.1 MJ/kg. Residue analysis shows 30% FC, 15% VCM, 40% ash and 15% H.0
. Air supplied is 50% in excess and is saturated at 25 °C, 740 mm Hg. Molar ratio of Co, to
CO is 5:1 and H, to CO is 1:1. The stack gas leaves at 300 °C and 765 mm Hg. Calculate:
a) orsat analysis of the stack gas
(7.97% CO2 , 1.59% CO, 1.59% H2 , 11.15% O2 ,77.69% N, )
b) m³ stack gas/ m³ air
