Efisiensi Energi dan Sebaran Kalor Pada Tungku Berbahan Bakar Cangkang Kemiri
MetadataShow full item record
Energy efficiency to boil 1 liter of water by using a candlenut shell as fuel is about 3.95 %. When we compared, husk fuel efficiency reaches 7.6 %. The experiments are conducted on 3 variations based on stove reservoir buttom diameter, 6 cm, 9 cm and 12 cm. Experiments showed that the diameter of 6 cm has the highest efficiency that is 4.19%, then the diameter of 9 cm is 3.92%, and the lowest is 3.72% on the diameter of 12 cm. Experiments on candlenut shell fuel also be variation in size, is the small size (shells was crushed first) and size large shell (shells was not destroyed first). Its efficiency showed that the large size of shell has a higher efficiency than the small one. Have also analyzed the distribution of heat in a stove reservoir by solving the equations of one-dimensional heat distribution using finite difference method that approach implicit scheme.
