Utilization of Animal Power for Low-Density Briquettes Production
Abstract:
Draught animals have been the backbone of Indian agriculture through ages for supplying draught power. Animal operated implements available in the country are primarily meant for field operation and haulage. Therefore animals remain idle for a considerable period for which the farmer continues to provide fodder and shelter. It is estimated that the annual use of animals is limited to 300-350 hours only but the potential use of animal in a year is nearly 1800 hours. To achieve this target an appropriate, cost effective and easy to operate biomass briquetting machine operated by animal power rotary mode unit was developed. The machine was tested to produce low density briquettes by different biomass like charcoal, paddy husk, pigeon pea stalk and saw dust. On the basis of proximate analysis charcoal briquette has highest calorific value of 4480 Kcal/kg followed by pigeon pea stalk, saw dust and paddy husk having calorific value of 4200, 3890 and 3200 Kcal/kg respectively. The highest machine efficiency was 88.33 % for charcoal briquette followed by 85.76%, 86.00% and 83.20% for paddy husk, pigeon pea stalk and saw dust briquette respectively.
