Summary:Premixed flames are widely used in domestic cookers. However, full utilization of premixed flame is usually restricted by its narrow operation range. Redesigning the burner cap is the focus of the present study. Two swirl burners, where the swirling flow is induced by two different methods, are proposed. It is found that compared to the Benchmarking cooker, both swirl burners are able to yield a higher heating efficiency under most of the operation conditions tested. Swirl Burner II shows lower CO emission than the Benchmarking cooker. Besides, Swirl Burner II has wider operation range. However, there is no evidence that Swirl Burner I can reduce the pollutant emission, or enlarge the operation range.
