where the main gasification reactions occurred. The producer gas escaped
from the fluidized bed reactor and entered the fixed bed reactor,
where the main tar-cracking reactions took place. The producer gas
escaping the fixed bed reactor consecutively passed the char
removal system, the quenching system, and the EP. A flow of noncondensable
producer gas leaving the EP was sampled using Teflon
gas bags (1L) at an interval of 10 min to analyze its composition
using GCs.
