摘　　要：采用生物质燃料的分布式热电联供系统可以摆脱对化石燃料的依赖,有效利用生物质废弃物,应用前景广阔。基于塞贝克效应设计了一种温差发电热电联供系统,提出了新型的辐射式集热器,集成24个温差发电模块。通过测试样机的功率负载特性和供热特性,结果表明:发电功率超过36 W,对外供电超过22 W,对外提供清洁暖气超过1 200 W。此外,采用理论模型分析验证了实验数据,表明该温差热电联供系统已充分利用了每一个温差发电模块的发电能力,达到预期效果。Distributed combined heat and power(DCHP)system based on bio-fuel is promising due to its independence on fossil fuel and utilization of biomass wastes.A DCHP system based on Seebeck effect was designed,which is featured by a novel radiation-type heat collector and incorporated with 24 thermoelectric modules.Detail power load feature and heat supply were tested.The results showed that the electric power was over 36 W,external power supply was 22 W,and external clean heating was more than 1 200 W.Besides,a theoretical model was adopted to analyze and verify the experimental data,and results revealed that the proposed DCHP system exerted the potential of every thermoelectric generation module as expected.
