Carbureted water gas is produced in the same way as blue water gas but in the presence of cracked oil vapors in a carburetor. A typical gas analysis shows 4.7% CO2, 7.8% C2H4, 0.3% O2, 36.5% H2, 35.5% CO, 8.6% CH4 and 6.6% N2. If this gas is saturated with H2O at 20°C, 742 torrs and burned in 10.434 m3 air at 30°C, 101 kPa and 60% RH per m3 fuel, calculate: a) % excess O2 (183%) b) Orsat analysis of the stack gas (400°C, 760 torrs) if 85% of C burns to CO; all H2 burns to H2O. (5.33% CO2, 0.94% CO)

Question
Carbureted water gas is produced in the same way as blue water gas but in the presence of cracked oil vapors in a carburetor. A typical gas analysis shows 4.7% CO2, 7.8% C2H4, 0.3% O2, 36.5% H2, 35.5% CO, 8.6% CH4 and 6.6% N2. If this gas is saturated with H2O at 20°C, 742 torrs and burned in 10.434 m3 air at 30°C, 101 kPa and 60% RH per m3 fuel, calculate:
a) % excess O2 (183%)
b) Orsat analysis of the stack gas (400°C, 760 torrs) if 85% of C burns to CO; all H2 burns to H2O. (5.33% CO2, 0.94% CO)
c) GCV in MJ/kgmol (391.68)
d) % calorific value lost due to:
i) CO (6.984)
ii) Uncondensed water Vapor (7.79)
iii) sensible heat (34.84)
