“…The oblique angle plays the dominant role in the influence on the flame structure at lower heating heights but has a very small impact on the flame structure at higher heating heights. Wae-hayee et al 77 conducted a further study on the influences of burner-to-plate distance (H/ d) and LPG flow rate on the stove's thermal performance. Figure 10 shows the effect of the injecting angle and the burner-to-plate distance on flame behavior.…”

Cooking is a daily activity in every household, which consumes energy and produces pollution. Using clean gas fuels instead of traditional solid fuels will significantly reduce household air pollution. Although the use of clean-burning burners can reduce emissions, early domestic gas cookers had poor thermal performance. Currently, even small improvements in efficiency can result in significant energy savings due to the large number of domestic gas stoves in use. There has been a long history of research into the development of domestic gas stoves to improve performance and reduce energy consumption. Meanwhile, research into the use of hydrogen-enriched natural gas as a promising environmentally friendly fuel is increasing. In this paper, we perform a descriptive statistics and graphical visualization of network analysis by combining common databases with Bibliometrix. We also analyze the energy balance of domestic gas stoves and the influence of a single factor and multiple factors on stove performance. Then we provide a detailed overview of some research technologies in enhancing the thermal performance of gas stoves. We also discuss the research progress and application prospects for the use of hydrogen-enriched natural gas as a fuel in domestic gas stoves and identify areas for future research and issues that need attention.

“…An attempt has been made to investigate the different thermodynamic parameters viz., velocity, pressure, and temperature using commercial for evaluation of performance for a conventional burner and flame shield burner. [7][8][9] Naeemi and Hashemi, 10 studied the important and vital liftoff phenomenon in micro-thermophotovoltaic systems. Based on their numerical results, it can be said that the use of convergent and convergentdivergent combustion chamber decreases liftoff velocity.…”

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.

“…Their experiment results hold good agreement with numerical. Wae-hayee et al [2] studies the effect of distance between plate and burner on LPG consumption and heat transfer. They found the highest heat transfer rate at H/d between 25 and 35, KB-5 LPG burner is employed in this work by the authors.…”

Working process of domestic gas stoves primarily depends on the heat transfer phenomenon between gas flame and the bottom of the cookware. Various energy losses during this heat transfer results in low thermal efficiency. This work focuses on improving heat transfer ability of cookware, thus enhancing thermal-efficiency. Increase in rectangular fin height H causes increase in thermal efficiency value up to a certain limit after which a decreasing trend is observed by both numerical and experimental results. The fin height H=14.6 mm is considered optimum value for thermal efficiency. After H=14.6 mm, the maximum temperature value of fins shows a constant trend up to certain limit. Fin width variation follows a linear increase trend as the width increases up to 5 mm where fluctuation in efficiency stops. Max temperature of fins shows good agreement with increase in fin width in both numerical and experimental values up to W= 4.8 mm after which 10c temp loss occurs due to localized heat losses. Lastly fin spacing is verified against overall thermal efficiency and gradual; decrease is found in efficiency with increasing spacing due to formation of hotspots in between each fin. Lowest efficiency of 57% observed at fin spacing of 7 mm.
