Cavalcante Junior %A Lutero C. de Lima %J International Transaction Journal of Engineering, Management, & Applied Sciences & Technologies %D 2012 %I %X The monitoring of oxygen percentage in flue gases is one of various ways of controlling efficiency and emissions of industrial combustion. In general, flue gases analyzers are expensive and not accessible to small scale industries. The automotive Lambda sensor is an oxygen sensor which controls the electronic injection of the modern internal combustion vehicles. The aim of this study is to present two methods of measuring the oxygen concentration in flue gases of industrial combustion by the use of the automotive Lambda sensor. One method uses the voltage signals of a heated Lambda sensor and the other one uses the Current Reversal Mode (CRM) of operation of such sensor. Results presented in this article show that such methods are effective to control industrial combustion. %K Industrial combustion %K Lambda sensor %K Oxygen content %K Current Reversal Mode %U http://tuengr.com/V03/203-211.pdf
