A Comparative Study of Biogas Utilization Between Generating Electricity and Hot Water Production for Piglet Heating in a Small Pig Farm
This paper presents a comparative study of biogas utilization between generating electricity and hot water production for piglet heating in a small pig farm. The modified diesel engine was used and installed with the 128 kW-generator for generating the electricity from biogas. The engine was tested to study the efficiency and specific fuel consumption. The hot water production system for piglet heating was designed and constructed by using two heat sources which were biogas and waste heat from biogas engine. The efficiency of the heating production system and specific fuel consumption were also determined and compared with that obtained from power generating system. From the experiment, the result showed that the electrical efficiency and the specific fuel consumption were 10% and 1.70 m3/kWh, respectively. The thermal efficiency of the heating production system and the specific fuel consumption were 81% and 0.20 m3/kWh, respectively. When using the waste heat instead of biogas in the heating production system, it was found that generating both electricity and heat of the engine increased the overall efficiency to 11% and decreased the specific fuel consumption to 1.59 m3/kWh. It was indicated that the specific fuel consumption using biogas for electricity generation was 8.63 times higher than that using biogas for heating production system.
