[Gasification] Regarding Combustion Quality of Producer gas

Greetings Vikrant,
Generally, when talking about the quality of producer gas (PG) we talk of
the percentage of Hydrogen (H2), natural air driven systems range from 6%
H2, to good quality systems that produce upwards of 30% H2 content.
If one moves to a oxygen based system (SG) Synthisis Gas, the H2 content
pushes the 60% and up level, If one moves to externally driven systems, I
am told they are even higher than that.
