“…This study searched for relevant articles published between January 2012 and May 2023 in common databases, including Web of Science (Core Collection), Scopus, Wiley, Springer, and Science Direct. To retrieve the documents and to include all studies in the field of thermal performance of domestic gas stoves, the following search string was constructed and entered into the above databases: (stove) OR (cooker) OR (cooktop) LPG a comparison of the performance differences between a novel porous radiant burner and a conventional burner experimental Zhang et al 50 NG effect of changes in natural gas composition on the stove's performance experimental Zhen et al 28 LPG developed and compared the performance of two different swirling burners experimental Chen et al 51 PNG/ LNG flame stability of partially premixed combustion for PNG/LNG interchangeability experimental Wu et al 52 CH 4 research on porous metal burners for domestic gas stoves experimental Grima-Olmedo et al 53 biogas comparison of the stove's thermal performance using landfill and digester biogas experimental Boggavarapu et al 21 LPG/NG improving the stove's thermal performance by installing a circular insert and a radiant sheet experimental and numerical Mishra et al 40 LPG performance of a double-layer PMB in the LPG cooker experimental Keramiotis et al 41 NG performance of a PMB using natural gas experimental Iral and Amell 54 NG performance study of a domestic porous radiant burner at high altitude experimental Zhang et al 55 NG effect of variations in the natural gas component on the primary air coefficient for domestic gas stoves experimental and analytical O ̈zdemir and Kantaş5 6 CH 4 effect of operating conditions and design characteristics of a stove on the combustion performance experimental and numerical Laphirattanakul et al 39 LPG effect of porosity geometry on the stability of porous radiant burners general Panigrahy et al 57 LPG combustion performance of a domestic LPG cooker with PMB experimental and numerical Fumey et al 58 H 2 development of a novel gas stove based on catalytic hydrogen combustion experimental Zhen et al 59 CH 4 /H 2 effect of air preheating on the visual, thermal, and emission characteristics of HENG experimental and theoretical Laphirattanakul et al 33 LPG effect of a central cone-shaped bluff-body on the combustion performance of a domestic gas burner numerical Mishra and Muthukumar 60 LPG development of a self-aspirating LPG cooking stove with a two-layer porous radiant burner experimental De Vries et al 61 HENG interchangeability analysis for domestic appliances using HENG fuels theoretical and analytical Zhou et al 62 NG combustion performance of a domestic gas stove at different altitudes exp...…”

“…They suggested that a high level of mixing can increase the entrainment ratio by increasing outlet diameter and structural optimization. Laphirattanakul et al 33 reported a way to improve the air entrainment rate by adding a needle rod in a circular nozzle. They compared the effect of the nozzle with a circular bluff-body and a conical bluff-body on the combustion performance of a premixed burner.…”

“…In addition, the thermal performance of the burner can be maximized by optimizing the impingement flame. Some studies have shown that higher vortex angles result in higher tangential velocities and also allow more ambient air to be entrained into the burning jet, resulting in improved flame propagation. − As the combustion process is also influenced by the mixing effects of air and fuel, most studies are conducted through numerical simulations, which investigate jet characteristics to obtain a significant amount of entrained mass. , The shape and diameter of the nozzle, the nozzle position, and the ejector geometry are considered to be the main factors affecting the mixing effects of fuel and primary air . In addition, the stove’s thermal performance can also be effectively enhanced by installing a circular shield to reduce heat loss or by using a porous media burner (PMB) to achieve heat recirculation .…”
