摘要:

针对燃气内燃机出口排气流量和排气能量难以测量的问题,提出了碳平衡法和氧平衡法两种估算方法。以某分布式能源燃气内燃机测试数据为例,对影响其估算精度的各个因素进行分析,得出结论:估算精度主要受烟气成分、天然气流量、CH4含量影响;在烟气成分测量误差相同的情况下,采用碳平衡法估算排气流量和排气能量的误差较氧平衡法小。

Abstract:

According to the limitations in measuring exhaust gas flow and energy,two estimation methodsnamely carbon balance method and oxygen balance methodare introduced.Taking  performance test results of a distributed energy internal combustion gas engine as exampleall the factors influencing estimation precision are analyzed.The analysis shows that flue gas componentsnatural gas flow and CH4 content are the major influencing factors.Error of exhaust flow and exhaust energy estimated by carbon balance method is smaller than that by oxygen balance method with the same smoke component measurement error.
