“…However, when this two-region PRB is under low heat load, the fuel has difficulty igniting and burning at its downstream surface. Bakry et al 74 conducted a systematic investigate to explore this phenomenon. It was found that the limiting excess air ratio (λ) led to abnormal combustion, which would result in two different combustion modes.…”

“…The PM material in the upstream section has a low porosity and poor conductivity, which serves as the preheating zone since combustion cannot occur in this section and prevents flashback formation. 74 The PM material in the downstream section has a high porosity and good conductivity, which serves as the combustion zone to provide a place for fuel burning. When the fuel ignites at the surface of the combustion zone, it immediately propagates in an upstream direction and finally stabilizes after reaching the intersection of the preheating zone and the combustion zone.…”

“…When the fuel ignites at the surface of the combustion zone, it immediately propagates in an upstream direction and finally stabilizes after reaching the intersection of the preheating zone and the combustion zone. 74 The material of the two-region PRB can also have a significant effect on burner performance. Pantangi et al 133 presented the effect of burner diameter and operating parameters on the performance of a two-region PRB on a domestic cooker.…”

“…The two-region PRB has a wide spectrum of useful practical applications because they can stabilize the combustion wave within the PM. − The two-region PRB has a two-layer structure. The PM material in the upstream section has a low porosity and poor conductivity, which serves as the preheating zone since combustion cannot occur in this section and prevents flashback formation . The PM material in the downstream section has a high porosity and good conductivity, which serves as the combustion zone to provide a place for fuel burning.…”

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.
