摘要：A novel electric preheated porous media burner (PMB) of liquid fuel spray with three flame types is investigated experimentally. Liquid diesel (0#) is used in the burner to understand its combustion characteristics. The evolution of the flame characteristics in a single injection cycle is determined from the influence of the height of the foam ceramic on the spray characteristics,and the stability of the preheating temperature. The influence of the air flow and the fuel injection on the temperature inside the burner is also investigated. The results show that a ceramic foam at a distance of 3 cm from the nozzle improves the combustion of the fuel spray. The critical preheating temperature for a successful combustion of the burner is 689 degrees C. The flame is composed of a small flame, a moving flame, and a filtering flame with corresponding moving speeds of approximately 0 mm/s, 0.1 mm/s, and 1 m/s. Our results prove the feasibility of continuous combustion of diesel in an electric preheated PMB and reveal the distribution of the temperatures within the burner.
