This thesis presents pioneering experimental and numerical
studies on three aspects of the combustion characteristics of
lean premixed syngas/air flames, namely the laminar flame speed,
extinction limit and flammability limit. It illustrates a new
extinction exponent concept, which enriches the combustion
theory.
This thesis presents pioneering experimental and numerical

lean premixed syngas/air flames, namely the laminar flame speed,
extinction limit and flammability limit. It illustrates a new
extinction exponent concept, which enriches the combustion
theory.
Above all, the book provides the following: a) a series of
carefully measured data and theoretical analyses to reveal the
intrinsic mechanisms of the fuel composition effect on the
propagation and extinction of lean syngas/air flames; b) a mixing
model and correlation to predict the laminar flame speed of
multi-component syngas fuels, intended for engineering
computations; c) a new “extinction exponent” concept to describe
the critical effects of chemical kinetics on the extinction of
lean premixed syngas/air flames; and d) the effects and mechanism
of the dilution of incombustible components on lean premixed
syngas/air flames and the preferential importance among the
thermal, chemical and diffusion effects.
