Mathematical model of a new multi-burner entrained flow coal gasifier was established to predict its fluid flow distribution.In this model

non-premixed combustion method was applied to compare the flow field properties of this new coal gasifier with that of the single burner gasifier

and analyze the changes of coal gas component and temperature under varying load conditions.The simulation results show that

compared with the single burner gasifier

the new coal gasifier had more uniform flow field distribution and higher available components content.Under varying load conditions

as the auxiliary burner inclination angle rose

the available components content decreased and the syngas temperature dropped.With an increase in the feed stock flow proportion in main burner

the available components content in syngas increased first and then decreased

while the syngas temperature increased gradually.
