Estimation method for exhaust gas flow and energy of gas internal combustion engine

Abstract

Abstract:

According to the limitations in measuring exhaust gas flow and energy,two estimation methods，namely carbon balance method and oxygen balance method，are introduced.Taking performance test results of a distributed energy internal combustion gas engine as example，all the factors influencing estimation precision are analyzed.The analysis shows that flue gas components，natural gas flow and CH4 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. 
