Embodiment 1

[0030] like figure 1 As shown, the high-efficiency combustion and low-pollution emission oil burner of the present invention includes an oil burner body 101, an oil burner nozzle 102 and an equal pressure air box 5. The oil burner body 101 is arranged in the equal pressure air box 5, and the equal pressure air box 5 The outside of the air box 5 is provided with a thermal insulation sealing box 13, and all the air supply for the oil burner comes from the isobaric air box 5. The oil burner body 101 includes an oil gun sleeve 1 arranged on its central axis and a primary air duct 2, a secondary air duct 3 and a classification air duct 4 which are sequentially sleeved on the periphery of the oil gun sleeve 1. The classification air duct 4. Both the secondary air duct 3 and the primary air duct 2 have the same central axis as the oil gun sleeve 1; specifically, the outer wall of the oil gun sleeve 1 is fixed with a first support frame 14, and the primary air duct 2 passes through th...

Abstract

The invention discloses an oil burner with high-efficiency burning and low pollution emission. An oil burner body comprises an oil gun sleeve, a primary air pipe, a secondary air pipe and a grading air pipe, wherein the oil gun sleeve is arranged on the central axis of the oil burner body; the primary air pipe, the secondary air pipe and the grading air pipe are sheathed at the periphery of the oil gun sleeve; the grading air pipe, the secondary air pipe and the primary air pipe are respectively in the same central axis with the oil gun sleeve; a primary air channel is formed between the primary air pipe and the oil gun sleeve; the end part of the primary air channel is provided with a flame stabilizer; a secondary air channel is formed between the secondary air pipe and the oil gun sleeve; an axial cyclone with an adjustable axial position is arranged in the secondary air channel; a grading air channel is formed between the grading air pipe and the secondary air pipe, and an inlet position of the grading air pipe is provided with a tangential cyclone; and one end of the primary air pipe, which is far away from a nozzle of the oil burner, is provided with a flame segmenting ring. The oil burner has the advantages that high-efficiency burning and low pollution emission can be effectively realized, and the problems of incomplete burning with black smoke, and high pollutant emission and the like easily occurring on the original oil burner in operation can be effectively avoided.

Description

technical field [0001] The invention relates to an oil burner, in particular to an oil burner suitable for oil-fired boilers of various capacity levels, high-efficiency combustion and low pollution emission, and belongs to the technical field of burners. [0002] Background technique [0003] As a type of power plant boiler, oil-fired boilers have a small market share in China due to fuel costs and other reasons, but they still have a good market prospect in the world. The oil burner is one of the important components of an oil-fired boiler. The existing oil burner is mainly composed of an oil nozzle and an air regulator. The oil nozzle is placed on the axis of the air regulator to atomize the oil into fine droplets to The diffusion angle is sprayed into the combustion chamber, mixed with the air sent by the air regulator, and then ignited and burned. For oil burners used in oil-fired boilers, if the combustion and air distribution organization is not good, not only will a...
