<p>The Earth's limited reserves of fossil fuel are a matter of global concern as these are under threat of continuous depletion due to over exploitation. However, these finite reserves are concentrated in certain region of the world and would soon get exhausted. In view of the above problems, the search for alternative fuel has become extensively important. These alternative fuels should be renewable and eco-friendly. Thus, the use of non edible vegetable oil comes into focus. The main advantages of vegetable oils as fuel are ready availability, renewability, lower sulphur and aromatic content, and biodegradability. This is the innovative stove that has been developed can run on renewable non edible straight vegetable oils. The Vegetable oil is produced domestically which helps to reduce costly petroleum Imports. Development of the bio-fuel industry would strengthen the domestic, and particularly the rural, agricultural economy of agricultural based countries like India. It is biodegradable and nontoxic. It is a renewable fuel that can be made from agricultural crops and or other feed stocks that are considered as waste. However, the use of SVOs (straight vegetable oils) as a fuel is restricted by certain unfavorable properties, particularly their viscosity. In an agricultural based and petroleum importing country like India, there is a greater need to explore the use of vegetable oils as a fuel because of the possibility of large production capacity of these oils and producing it near the consumption points. Kerosene is most popular domestic fuel in rural parts of the country. Kerosene is meant to be used as a cooking, lighting or heating fuel that is heavily subsidized so that it can be purchased more easily by India's poor. However, with ever increasing cost of kerosene and huge subsidies by the government kerosene is fast disappearing from rural households. In the present innovation a new type of horizontal pressurized kerosene stove is developed which consists of two tanks. In one of the tank regular kerosene is filled and in another tank straight vegetable oil is filled. A new innovation has been done in the pipeline connecting this tank with the burner. A heating coil is provided here which preheats the fuel. Initially the stove is started on kerosene, after about 2 min when the preheating coil is heated up the valve 1 is slowly closed and valve 2 is slowly opened simultaneously, and finally valve 1 is completely closed and valve 2 completely open. Now the stove runs completely on straight vegetable oil. The tests on this stove are conducted for thermal efficiency and it is identified that the stove while running on straight vegetable oils has comparable thermal efficiency with the stove run on kerosene.</p> |
