| 摘 要： | 通过搭建小型实验平台,对基于燃气内燃机的热电联产系统在不同燃料下的机组性能和系统性能进行了探究。通过测得的发电功率和燃气流量计算出燃气发电机在不同负荷下的发电效率和燃烧功率,进而计算出不同燃料下热电联产系统的系统总效率并加以比较。试验结果表明,燃气内燃机组的发电效率和系统总效率随着电负荷的增大而增大;使用沼气作为燃料时,系统总效率最高可达到46.96%,高于使用液化石油气作为燃料时的系统总效率;用电负荷是影响系统各种效率的主要因素之一。

| Abstract: | A small experimental platform is set up based on CHP system of the internal combustion engine in different fuels,in order to explore the unit performance and the system performance.The power generation efficiency and burning power are calculated by the measurement of power generation and gas flow under different loads,and then the system total efficiency of CHP system are calculated and compared under different fuels.It is found that the power generation efficiency of the internal combustion engine and the system total efficiency increases with increasing the electrical load.The system total efficiency can reach 46.96% when biogas is used,higher than using LPG..The electrical load is one of the main factors affecting the various efficiency. |
