A Case Study On Biofuel Stove Technology: Jatropha As A Biofuel

Abstract

The study was done on Jatropha bio fuel stove technology. The study deals with comprehensive literature review followed by technical modifications. The wick stove proto type designed for kerosene burning was chosen for the study. The concepts for preliminary design and premodifications were drawn on the basis of observations received during testing of proto type to burn with Jatropha oil. Then final modifications of the wick stove were performed technically to make it compatible with burning Jatropha oil. The proto type after modifications contained 1.5 liters tank with three supporting stands. It contained wick burning mechanism exposed with loose 10 single rope cotton woven wicks each of diameter 5 -5.5 mm arranged in a ring. The length of wick was adjusted to 4.5 cm so that the jatropha oil can transport upward easily. The multi-wick mechanism allows for air flow to occur around its enclosed stilt barrel configuration. This has the effect of reducing heat transfer to the fuel vessel and reduces the potential fuel loss in the vessel through evaporation. The cooling effect on the stilt wick reduces the transfer of heat to the fuel vessel, and thus the fuel within the fuel vessel remains below the dangerous flashpoint temperature even after long periods of use. Closer to the top of the enclosed stilt areas become hot during stove use. This has the effect of heating up the air that enters the burning area, thus making the stove more efficient.
