The role of exhaust gas recirculation in flameless combustion

Abstract

Recently, flameless combustion has been developed as an innovative combustion method to intensify combu stion performance and to decrease the pollutant formation contemporaneously . The outstanding econ omic aspects and merits of flameless combustion have persuaded the combustion scientists to investigate about this unique technology in the various ways and conditions . In flameless chambers the roles of heat and mass transfer are more highlighted than traditional combustion d ue to Exhaust Gas Recirculation (E GR) method. Flameless systems are characterized by h ighly preheated combustion air and burned gases recirculation before reaction. T his paper is concerned with the detailed theoretical analysis of thermodynamics relationships in flameless combustion method.
