Energy is a primary and basic question for living things of peoples to lead their life. rnEnergy is a key factor for the development of one country. Energy demand increases withrnrespect to the population size. Energy is utilized from different sources for conducting day tornday activities of human beings. Even though there exist so many sources of energyrndeveloping and under developing countries relays on biomass energy sources for cookingrnpurposes. Biogas is a fuel which can be obtained from different sources like animal manure,rnanimal slaughter, plants, sewage, ruminant, etc. biogas encompasses different gasesrndepending on the sources such as, methane, carbon dioxide major constituent while hydrogenrnsulfide, hydrogen, nitrogen may include. rnBy doing so we human being faces a number of problems such as shortage of cooking rnfuel, health problem due to emission of firewood, air pollution, acid rain formation dependingrnon the content of emissions and ozone layer depletion those are the typical challengingrnproblems which encounters our surrounding. The main aim or goal of this research paperrnminimizing or overcoming previously mentioned problems that come due open fire stovesrnmost commonly. In order to implement this paper we were used the following methodologyrndata collection of biogas thermal property and baking clay pan thermal property; input fuelrncontent; knowing biogas properties its composition as well as flow rate; chemical kinetics ofrnbiogas, determined dimension of ,3D burner assembly using CATIA, design of flame portrngeometry,3D flame port assembly by CATIA, design of insulation layer were have been donernfinally we manufacture the optimized burner geometry and carried out the experimentalrninvestigation hence we obtain the result of 22.1% thermal efficiency the prototype somewhatrnportable and can be movable able to bake by transporting somewhere we desired, the burnerrnables to drive biofuel uniformly to the beanth of clay mitad because of flame port geometryrnorientation and distribution over the circular flame port surface. Here we can deduce that thisrnstove ables to distribute heat to mitad uniformly as can be observed from the experimentalrninvestigation rnBiogas used for power generation, thermal heating upon with modification of utilizing rnequipmentâ€Ÿs. Biogas generates heat energy up on combustion reaction with in the combustionrnchamber.
