Study on Diesel Atomization Characteristics for Hot Exhaust Gas Burner 2019-01-2238
A hot exhaust gas burner system is applied to break through the limitations of the traditional diesel engine bench. Sufficient atomization is needed to realize spark ignition in a low-pressure burner system. Hence, the design of the atomization system is studied both experimentally and numerically. Through the reasonable optimization of the nozzle diameter, the air assist pressure, the angle among the four nozzles of four V-structures as well as the diameter and the angle of co-flow holes, an even distribution of small diesel droplets in the ignition area of the burner is realized. Consequently, diesel spray can be spark ignited in a low-pressure burner system, which can simulate the diesel exhaust. And the DPF can be installed downstream of the burner to quickly analyze the effect of ash accumulation on the DPF.
