Abstract
Gasification and combustion of de-oiled Pongamia Pinnata seed cake is done to produce higher energy biomass waste heat "syngas" for generating power using hybrid thermoelectric generator (TEG). A test rig is fabricated and experiments conducted with synthetic oil (Therminol-55) as the heating fluid under water and aircooled methods. The hot side temperature is varied from 200 - 250ฐC while the coolant temperature is maintained at 30ฐC for both water and air respectively. Experimental results showed 22.27% enhancement in electric power at a constant hot side temperature of 250ฐC under water cooled method. In addition, simulation results for the above mentioned conditions using artificial neural networks (ANN) tool in MATLAB also agreed well with the sample experimental results. The performance parameters such as open circuit voltage, maximum output power and matched load resistance are forecasted using ANN upto maximum possible hot side temperature of 350ฐC. Further, the financial evaluation of Biomass gasified-thermoelectric system ($0.0018/kWh and in terms of Indian currency is Rs 0.0676/kWh) is found to be almost negligible on comparison with other available renewable energy technologies. ฉ 2018, Yildiz Technical University.
