PRE-MIXING COMBUSTION METHOD AND BURNER

摘要

The invention relates to a method of combusting many kinds of fuels, particularly heavy oil, tar and coal powder and burners. The method is: the pressured air injects into a mixing zone in the body of the burner through a second nozzle in which fuel extracted by means of the high speed injection of air mixes with air and is ignited there. The combustion gas is combusted further through the combustion zone and soaking zone and then enter furnace chamber. This burner may not use a conventional high pressure oil pump, but a secondary heating system, a blower and an ash removing system and can ensure that oil combusts completely. The nozzle can run a long time without slag, boinding and plugging. The temperature of the outlet of the burner may be regulated. The burner is suitable for the industrial furnace whose operating temperature is in a range of 50-1600 DEG C.
