Thermoelectric Combined Heat and Power Generation System Integrated with Liquid-Fuel Stove
Keywords:thermoelectric, TEG CHP, heat transfer, kerosene stove
Liquid-fuel stoves (kerosene heaters) are extensively used in developed and non-developed countries and rural communities. In addition, these stoves are generally common due to their convenient fuel cost for space heating. Moreover, the possibility of using these stoves for water heating and generating electricity represents an extra benefit. This study presents an application of thermoelectric devices to a liquid-fuel stove to concurrently charge a 12-V lead-acid battery and transfer heat to circulating water for heating or normal household purposes. The feasibility of the proposed thermoelectric generator (TEG) for combined heat and power system is demonstrated for a common kerosene indoor stove. This system generates an average of 235Wth and 12.2Wele (19Wel peak) during a three-hour-long burning experiment. The proposed system produced 0.25 Wel/cm2 on average on the TEG area in which the obtained TEG efficiency is around 5%.
