6. A high grade semi-anthracite coal has a complete analysis of 85.86% C, 4.44% H, 2.7% O, 1.2N, 5% ash and 0.8% S. Analysis of the Residue shows 58% C and 42% ash. Air is supplied dry at 30°C and 750 mm Hg. Partial orsat analysis of the stack gas (400 °C , 755 mm Hg) shows 8.05% CO2 , 2.42% CO and 2.9% H2 . Assume that the S and N gasified burns to SO2 and NO respectively. Calculate: а) % excess 02 b) Complete orsat analysis of stack gas (10.611% O2 , 75.843 % N2 , 0.04% SO2, 0.136% (54.4) NO) 3 c) m stack gas/ m³ air (2.313)

Transcribed Image Text:6. A high grade semi-anthracite coal has a complete analysis of 85.86% C, 4.44% H, 2.7% O,
1.2N, 5% ash and 0.8% S. Analysis of the Residue shows 58% C and 42% ash. Air is supplied
dry at 30°C and 750 mm Hg. Partial orsat analysis of the stack gas (400 °C , 755 mm Hg)
shows 8.05% CO2 , 2.42% CO and 2.9% H2 . Assume that the S and N gasified burns to SO2
and NO respectively. Calculate:
a) % excess O2
b) Complete orsat analysis of stack gas (10.611% O2 , 75.843 % N2 , 0.04% SO2, 0.136%
