This article mainly focuses on testing and analyzing the problems of high flame height and large size for combustion system in current gas water heaters,and proposes corresponding optimization solutions by combining nu-merical analysis and experimental verification.Through the redesign of the injector section,head,and burner shape of the burner,the micro-flame combustion technology was proposed,and the flame height was reduced by more than 25%.By designing a coil-free air cooling combustion system and optimizing the primary and secondary air coefficients and flame uniformity of the combustion system,the volume of the combustion system was reduced,enabling the application of micro-flame combustion technology in small-size gas water heaters.
