Energy is a primary and basic question for living things of peoples to lead their life. Energy is a key factor for the development of one country. Energy demand increases with respect to the population size. Energy is utilized from different sources for conducting day to day activities of human beings. Even though there exist so many sources of energy developing and under developing countries relays on biomass energy sources for cooking purposes. Biogas is a fuel which can be obtained from different sources like animal manure, animal slaughter, plants, sewage, ruminant, etc. biogas encompasses different gases depending on the sources such as, methane, carbon dioxide major constituent while hydrogen sulfide, hydrogen, nitrogen may include. By doing so we human being faces a number of problems such as shortage of cooking fuel, health problem due to emission of firewood, air pollution, acid rain formation depending on the content of emissions and ozone layer depletion those are the typical challenging problems which encounters our surrounding. The main aim or goal of this research paper minimizing or overcoming previously mentioned problems that come due open fire stoves most commonly. In order to implement this paper we were used the following methodology data collection of biogas thermal property and baking clay pan thermal property; input fuel content; knowing biogas properties its composition as well as flow rate; chemical kinetics of biogas, determined dimension of ,3D burner assembly using CATIA, design of flame port geometry,3D flame port assembly by CATIA, design of insulation layer were have been done finally we manufacture the optimized burner geometry and carried out the experimental investigation hence we obtain the result of 22.1% thermal efficiency the prototype somewhat portable and can be movable able to bake by transporting somewhere we desired, the burner ables to drive biofuel uniformly to the beanth of clay mitad because of flame port geometry orientation and distribution over the circular flame port surface. Here we can deduce that this stove ables to distribute heat to mitad uniformly as can be observed from the experimental investigation Biogas used for power generation, thermal heating upon with modification of utilizing equipment‟s. Biogas generates heat energy up on combustion reaction with in the combustion chamber.
