What is in the gas that comes out of the gasifier?
Whilst the exact gas composition will be particular to the feedstock and operating conditions, typical gas composition from an air-blown gasifier is around 20% carbon monoxide (CO), 18% hydrogen (H2), 10% carbon dioxide (CO2), 1% methane (CH4) and 51% nitrogen (N2). It is a very high octane but low specific energy gas mixture that has a relatively low flame temperature and combustion flame speed due to the large amount of dilution gases (CO2 and N2) present.
