Even at the national level, the domestic market, commonly used cooking fuel in India and many other which is dominated by cooking energy consumption, countries on the globe. LPG cook stoves are consumes 40% of total energy [4]. Aside from energy comparatively very efficient, clean, need low considerations, the type of cooking fuel used, its maintenance, and are portable too. Because of these consistency, availability, and accessibility, as well as benefits and the subsidy provided by the Indian the cooking device used and its efficiency, all affect Government for LPG cylinders, the use of these burners women's quality of life, especially in rural areas. for cooking purposes has become popular in urban and Despite the fact that cooking energy plays a dominant sub-urban India. role in the Indian energy landscape, little has been done to systematically analyse the cooking energy In the initial stage, different geometries and designs of options available to potential consumers in terms of LPG stovetops are tested for their parametric influence quality, economics, and services given. on thermal performance and emissions. It was observed that, as per literature, no work has been done on the 1.2 Combustion System nozzle angle of burner holes. We proposed three different burner hole configurations at optimized angles The conversion of thermal energy from a combustion as per base paper. We performed ANSYS fluent analysis process to a load used in cooking applications relies on for this burner configuration to find out the best thermal four components. The burner is one part that burns the efficiency of the proposed design. Thermal efficiencies of fuel with an oxidizer to generate heat. Another factor is these burners are increasing up to a certain power range the load, which has a significant impact on how heat is and then decreasing sharply with an increase in firing transferred from the burner to the load. The third rate. CO and NOx emissions are decreasing with the component in cooking is the flow control unit, which increase in thermal efficiency. Thermal efficiency of the controls the rate of fuel and oxidizer flow, and the burners varies with material, pattern, number and size fourth component is the fuel. of holes on the burner tops. It was observed that swirling of flame increases thermal efficiency compared to flat 1.3 The Burner's Configuration flames and a reduction in NOx and CO is also observed compared to flat flames. A burner is a system that burns fuel and uses an oxidizer to transform the fuel's chemical energy into Key Words: Liquefied petroleum gas (LPG), burners, thermal energy. A burner may be categorised as an cook stoves, performed ANSYS fluent analysis, Thermal industrial or commercial heating burner or a domestic efficiency, firing rate cookstove, depending on the end usage. In addition, the burner may be used in flameless or flame mode. 1. INTRODUCTION Depending on whether the fuel and oxidiser are mixed before combustion or the oxidiser is supplied during 1.1 Energy Demand and Crisis combustion, a burner can be premixed or diffused. A domestic cook stove is a form of partially premixed In developing countries like India, the rural energy induced air burner that is now used for flame heating. crisis was followed by a scarcity of cooking fuels, As a result, several factors affect the design of a burner, especially firewood. Cooking is the most energyincluding material, burner structure, fuel intensive operation in the village energy matrix, characteristics and velocity, air fuel ratio, mixing tube according to studies conducted in various parts of India 2Assistant
