“…33 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. 34 Most studies focus on the influence of the position and shape of the shield on the flue gas and the thermal efficiency of the burner. 21,35,36 This is because heat transfer can be enhanced by efficiently circulating the burned gases around the vessel and prolonging the heating time of the burned gases.…”

“…The thermal performance of gas stoves is mainly influenced by combustion efficiency of the burner and heat transfer performance between the burner and the vessel . The principle of the current thermal performance enhancement technology for domestic gas stoves is based on these two methods, such as improving structural optimization, , applying the swirl flow, enhancing mixing of air–fuel, , reducing heat loss, heat recirculation using porous medium, optimizing fuel composition, etc.…”

“…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 . Most studies focus on the influence of the position and shape of the shield on the flue gas and the thermal efficiency of the burner. ,, This is because heat transfer can be enhanced by efficiently circulating the burned gases around the vessel and prolonging the heating time of the burned gases.…”

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.

“…Focusing on the environmental sustainability of PRB, works on Life Cycle Assessment (LCA) of PRB's impact on the environment have been performed. LCA is performed to analyze the environmental sustainability of a product or a process or a service [7]. It is also performed to compare the environmental impacts of two or more products or processes or services and will act as a decision-making tool to make a choice on the optimal one.…”

“…Their assessment proved that as PRB has higher thermal efficiency, it led to higher LCEE. In a similar study performed by the authors' research team, LCA was performed to compare the environmental impacts of PRB to the environmental impacts of CB; both operating at 1-3 kW power output and also for their fabrication [7]. The study exhibited that PRB had a 15% lesser negative impact on the environment compared to CB on all the endpoint damage assessment categories.…”

The present study is to conduct a Techno-economic Assessment of a 5-7 kW Porous Radiant Burner (PRB) – based LPG cook-stove operating in eateries and restaurants. Process flow study has been performed primarily to understand the technological process involved in the PRB and also to estimate the cost of manufacturing. The cost estimation has been done considering direct costs such as material costs and labor costs, and indirect costs such as factory costs, works costs and administration costs. Sensitivity analysis has been performed considering the production capacity of 50, 250 and 500 cook-stoves each day. An economic feasibility study of PRB cook-stoves has been done by estimating the Pay Back Period, Net Present Value and Internal Rate of Return. For a manufacturing capacity of 250 cook-stoves per day, PRB yields a 51.4% return on the investment with a payback period of 0.68 years. Adopting PRB-based cook-stoves in small, medium and large-scale eateries results in an annual saving of Rs. 77500, Rs. 235000 and Rs. 1170000, indicating that PRB-based cook-stoves are undoubtedly economically viable.
