Abstract: There have been several attempts to improve thermal efficiency of gas stoves by improving various parameters like flame stability, flame temperature, shape, size and aeration etc. including the burner heads. The spacing of ports, inclination of the flame cones, port geometry are also important parameters which govern the flow pattern of hot gases impinging on the heat exchanger vessel. Several gadgets are displayed on the market, claiming that they can improve thermal efficiency of the gas stove. One such gadget is the wire mesh disc, which placed over the burner head is claimed to improve thermal efficiency of the stove. The mesh is made of durable special compound metal alloy to withstand vigorous LPG heat. Interwoven wires enable concentrated high flame. Also, the utensils do not get blackened as no unburned hydrocarbons are produced. This work aims at quantifying the effect of add-on disc holding wire-mesh above the burner head on the thermal efficiency of the gas stove and to determine its optimum location to further improve the thermal efficiency. The experiments suggest that the use of wire mesh on burner head improves gas stove thermal efficiency. Use of this gadget will be beneficial, as it leads to saving of LPG, however small, and on a global scale, it will be a major step towards energy conservation as millions of stove operate globally.
