Electrical performance analysis and economic evaluation of combined biomass cook stove thermoelectric (BITE) generator.

摘要: The use of biomass cook stoves is widespread in the domestic sector developing countries, but are not efficient. To advance versatility stove, we investigated feasibility adding a commercial thermoelectric (TE) module made bismuth-telluride based materials to stove's side wall, thereby creating generator system that utilizes proportion waste heat. system, stove (BITE), consists TE (Taihuaxing model TEP1-1264-3.4), metal sheet wall which acts as one structure and serves hot module, rectangular fin heat sink at cold module. An experimental set-up was built evaluate conversion efficiency various temperature ranges. revealed electrical power output depended on difference between sides At approximately 150 degrees C, unit achieved 2.4W. 3.2% enough drive low incandescent light bulb or small portable radio. A theoretical approximated economic analysis indicated payback period tends be very short when compared with cost same supplied by batteries. Therefore, design formulated here could used sector. intended compete primary sources adequately an emergency backup source power.
