Abstract

Self-powered space and water heating systems operate entirely on fuel combustion with no need for externally generated electricity. Excess power can be used to charge batteries or be fed into the household grid to provide electricity for other electrical loads. Self-powered heating systems have the potential for high overall energy efficiency and can be more reliable in providing heat during extreme weather conditions. They are also attractive for remote communities where connection to the grid is not cost effective. To realize this concept, we must develop a reliable, low maintenance and cost-effective means to generate electricity and integrate it into fuel-fired heating units. In the present work, we investigated combustion-heated thermoelectric generation and its application to self-powered heating systems. A thermoelectric module with a power generation capacity of 550 W was integrated into a gas-fired furnace. The tin-telluride-based thermoelectric module has a radial configuration. The effects of heat transfer conditions were studied in order to maximize electric power output. The performance of the thermoelectric device was examined at various operating conditions. We have shown that the technology is attractive and offers the potential for practical applications

集成热电发电机及其在自供电加热系统中的应用

自供电空间和热水系统完全依靠燃料燃烧运行，不需要外部发电。多余的电力可以用来给电池充电，或者被送入家庭电网，为其他电力负载提供电力。自供电供暖系统具有整体能源效率高的潜力，在极端天气条件下可以更可靠地提供热量。它们对连接电网成本不高的偏远社区也很有吸引力。为了实现这一概念，我们必须开发一种可靠的、低维护成本和成本效益的发电方式，并将其整合到燃料加热装置中。在本工作中，我们研究了燃烧加热热电发电及其在自供电加热系统中的应用。将发电容量为550瓦的热电模块集成到燃气炉中。基于碲化锡的热电模块具有径向结构。为了使输出功率最大化，研究了传热条件的影响。测试了该热电器件在不同工作条件下的性能。我们已经证明，这项技术是有吸引力的，并提供了实际应用的潜力
