6. Coal tar fuels are liquid fuels obtained by blending coal tar distillation products such as carbolic oil, naphthalene oil, creosote oil, anthracene oil and medium pitch. A sample elemental analysis shows 85.9% C, 6.3% H, 1.2% S, 5.5% O and 1.1% N. If this fuel is burned in excess air at 30°C and 755 mm Hg with 90% RH, it produces a burner gas containing 10.64% CO2, 3.19 % CO and 0.64% H2. Assuming negligible N and S, Calculate: a) % excess air (27.18%) b) Complete orsat analysis of burner gas (6.41% O2 , 79.15% N2 ) c) m' stack gas (200 °C , 100 kPa)/kg çoal tar (22.03)

Transcribed Image Text:6. Coal tar fuels are liquid fuels obtained by blending coal tar distillation products such as
carbolic oil, naphthalene oil, creosote oil, anthracene oil and medium pitch. A sample
elemental analysis shows 85.9% C, 6.3% H, 1.2% S, 5.5% O and 1.1% N. If this fuel is burned
in excess air at 30°C and 755 mm Hg with 90% RH, it produces a burner gas containing
10.64% CO2, 3.19 % CO and 0.64% H2. Assuming negligible N and S, Calculate:
a) % excess air (27.18%)
b) Complete orsat analysis of burner gas (6.41% O2 , 79.15% N2 )
c) m stack gas (200 °C , 100 kPa)/kg coal tar (22.03)
d) AFR (15.3)
