This paper reports the combustion and emission characteristics of the premixed MILD combustion of propane established by a single jet burner in a laboratory-scale cylindrical furnace. Measurements are made of spatial distributions of the furnace temperature and species concentrations (O2, CO2, CO, and NO) and also exhaust emissions of CO and NO. Experiments are conducted for different values of thermal input, injection diameter, and global equivalence ratio (Φ). Results are analyzed with the aids of computational fluid dynamics (CFD) simulations and chemical kinetic calculations, which use a simplified perfectly stirred reactor (PSR) system with exhaust gas recirculation (EGR). It is observed that the premixed MILD combustion of propane in the present furnace can be established once the injection momentum rate is sufficiently high to enable the flue gas recirculation rate Kv > 2.5 (critical value) for Φ = 1.0. The critical Kv increases as Φ falls. Inlet conditions of the transition regime should be avoide...
