“…4 Residential sector is one of the main consumers of natural gas in a way that it accounts for 78% of total natural gas consumption. 5 Domestic burner is a gas-fired kitchen appliance which is fueled by natural gas for cooking purposes. Therefore, fuel consumption reduction in domestic gas-fired burners can lead to significant decrease in natural gas consumption and pollutant emissions as well as significant cost saving from a large-scale viewpoint.…”

Due to the wide spread use of household cooker burner, optimal design of these equipment can significantly reduce the natural gas consumption which consequently leads to energy consumption reduction, emissions reduction, and economic benefits. Shape of cooker-top and swirl angle are the most important effective factors on performance of domestic cooker burner. This paper investigates the impact of swirling the output port on performance of the burner, numerically. In this regard, four types of burners are three-dimensionally modeled and compared to determine the optimal port swirl angle based on burner temperature, heat transfer rate and pollutant emissions. Results show that the optimum swirl angle for output port is 20º where the maximum combustion temperature and desired heat transfer and pollutant emissions are obtained. The maximum burner head temperature for non-swirled burner is equal to 1610 K while for swirl angle of 20º, in addition to pollutant emissions reduction, the maximum burner head temperature of 1673 K is obtained. It is also concluded that the turbulence dissipation of flow increases by swirling the cooker-top burner.
