MILD Oxy-fuel Combustion

Abstract Oxy-fuel combustion can be combined well with moderate or intense low oxygen dilution (MILD) combustion to generate MILD oxy combustion, offering more advantages than standard oxy-fuel combustion. MILD oxy combustion can further reduce NOx and soot emissions, enhance combustion stability, and achieve a more uniform distribution of temperature. This chapter first introduces and reviews the recent progress made in MILD oxy combustion. Then the physical and chemical effects of CO2 addition on MILD oxy combustion are investigated. The burner configuration for MILD oxy combustion is also discussed. Based on the use of the MILD oxy combustion burner, an experimental study of MILD oxy combustion of pulverized coal is subsequently presented. A summary and concluding remarks are provided at the end of the chapter.
