Composition of the Syngas
Composition of syngas depends on the gasifier design, type of biomass used and operating conditions. Indicative compositions and lower heating values (LHV) of syngas produced in allo thermal, auto thermal, and entrained flow types of gasifiers are shown as an example in Table 11.1 [3]. The last column in the table shows the composition of syngas produced from coal in an entrained flow gasifier.
