dc.description.abstract The temperature variations of a biomass down draft batch feeding stove is analyzed. Down draft stoves are becoming more popular due to its low emission and high thermal efficiency. The principle of operation of the stove, in contrast to conventional designs is that the flow of air is in the same direction as the volatiles and fuel. Temperature distribution of the stove is important, because it has a direct relation with batch feeding. To explore the capability of using down draft stoves for other than cooking is very important and for that the temperature variation inside the stove has to be analyzed. A 150 mm X 150 mm grate size biomass stove is used and the chimney height is 1.5 m. Diameter of the chimney is 88mm and the average of 750 g of wood can be feed for a batch. Heat exchanger is used to extract heat form the chimney and the used air flow rate through the heat exchanger is 45 cm7S. The thermocouples are placed under the grate in-between grate and under the chimney inlet and on top of chimney outlet. And the temperature readings were plotted against time. Maximum temperature of 800 C is recorded in-between chimney and grate. And the all the temperatures shows an oscillation behavior, showing maximum Temperature during the middle of the feeding cycle and decreasing gradually. en_US
