摘要
热光伏是将高温热辐射体的能量通过半导体PN结直接转换成电能,有较高的能量输出密度及理论效率。在传统的热光伏系统只输出电能的基础上,加上热量回收装置,回收高温燃烧产物的余热和用于冷却光伏电池的冷却水的热量,组成了热电联产装置。通过数值模拟得到了燃烧室外壁面平均温度(1679K)、出口的排烟温度(1560K);利用数学计算方法分别计算出热光伏产生的电效率(14.07%)、回收余热的热效率(51.70%);最后得到了整体热电联产装置的总效率(65.77%)。
By using the TPV technology, thermal radiation can be converted into electricity through a semiconductor PN junction. The advantages of TPV included high power density outputs and theoretical efficiency. A traditional TPV system only output electric energy, but a CHP device which combined heat and power generation recycled energy of exhaust gases and energy of water which can cool photovoltaic cell. By using numerical simulation, the mean temperature of external wall of burner is 1679K; the exhaust gas temperature is 1560K. By mathematical calculation, the electrical efficiency and the thermal efficiency of TPV is 14.07% and 51.70% respectively, the overall efficiency of CHP is 65.77%.
