Abstract: For cogeneration of heat and power in off-grid areas and suburbs, particularly under emergency conditions, a micro combined heat and power (μCHP) system based on a stove-powered thermoelectric generator (SPTEG) was designed and tested. A strategy, which interlinks heat collection, thermoelectric (TE) module wiring, electricity conditioning and storing, and temperature control, is proposed for the simultaneous augmentation of electric power to over 200 W and heating power to over 9.8 kW. Temperature distributions, power load features, battery charging curves, heat collection, power generation, TE efficiencies, and material cost analysis were explored and discussed in detail. Results revealed that the SPTEG based μCHP (SPTEG-μCHP) system is a potential solution for improving the living conditions in off-grid areas and suburbs, especially under emergency conditions. However, further works should be carried out to investigate the heat collection aspect.
