POWER GENERATION WITH BIOGAS : AN EFFECTIVE AND ECONOMIC WAY FOR SUSTAINABLE AGRICULTURE AND POLLUTION FREE ENVIRONMENTM. Anitha, K. Thanunathan and V. Arutchelvan
Experiments were conducted to study the possibility and economic utilisation of biogas for generating electrical power, crop production with biogas slurry and way for pollution free environment. A 14 hp, I 500 rpm dual fuel engine with an alternator of I 0 KVA capacity was used for the study. The engine was exclusively run with diesel and it was compared with the biogas-diesel mixture for its rated capacity and economics of fuel consumption. The gas supplied to the engine was measured with a gas flow meter. It was found that the engine developed 9.35 kwh by consuming I 42.50 ml diesel / h / bhp whereas it developed 9.30 kwh by consuming 35.36 ml diesel h bhp and 0.44 m3/h/bhp biogas. Thus a saving of 75.2% diesel could be achieved besides getting nutrient rich manure. Further, it was proved that the engine performed well when it was loaded upto 90% of its rated capacity. The biogas slurry obtained was applied to ADT 38 rice crop 10.0 t ha- I. The growth, yield, nutrient uptake and post harvest nutrient status of soil were higher with bio-digested slurry application compared to FYM and control .
