| 摘 要： | 将汽油内燃机改装成燃气内燃机,搭建小型燃气内燃机CCHP系统实验台。对小型燃气内燃机CCHP系统的冷却系统余热和烟气余热及排放特性进行了研究。随着负载的增加,系统余热回收量增长,但其所占总能量比例降低,系统整体能源利用率在80%以上。发动机CO排放随着过剩空气系数增加而降低,NOx排放量在过剩空气系数为1.16达到最大值。

| Abstract: | The features are studied in the cooling system of CCHP based on small-scale gas engine. The recovery amount of waste heat increases with the increasing of the load, but its proportion to the total energy is reduced and the energy efficiency in such system is over 80%. The CO emission of engine decreases with the increasing of excess air factor and the NO x emission achieves the maximum value when the excess air factor is 1.16. |
