Inclined two-stage micro-oil gasification burner

Abstract

The invention relates to an oblique insertion type two-stage micro oil gasification burner which comprises an air distribution barrel, a first-stage oil burner body and a second-stage oil gun. The air distribution barrel is mounted in a secondary air duct. The second-stage oil gun is horizontally arranged in the air distribution barrel. The first-stage oil burner body is inserted into the air distribution barrel obliquely. The axis of the insertion direction of the first-stage oil burner body into the air distribution barrel and the axis of the insertion direction of the second-stage oil gun into the air distribution barrel form an acute angle. The flame of the first-stage oil burner body is used for lighting and stabilizing the flame of the second-stage oil gun and heating and gasifying the fuel oil of the second-stage oil gun. Compared with an existing large oil gun burner, multiple expensive components are omitted, the structure is simpler and more reliable, and manufacturing cost is lower. The first-stage oil burner body heats and gasifies the fuel oil of the second-stage oil gun, and original cold oil atomization burning of the second-stage oil gun is converted into hot oil gas burning of the second-stage oil gun. The boundary temperature during burning of the second-stage oil gun can be raised through high-temperature smoke generated during burning of the first-stage oil burner body, and therefore the oblique insertion type two-stage micro oil gasification burner has extremely high burning efficiency.

Description

technical field [0001] The invention relates to an oil burner for a boiler, in particular to an obliquely inserted two-stage micro-oil gasification burner. Background technique [0002] In the power industry, thermal power plants often use large oil gun burners when the boiler is started or stabilized. Such as figure 1 As shown, the existing conventional large oil gun burner includes an oil gun a1, an ignition gun a2, a travel switch assembly a3, a combined pneumatic actuator a4, an air distributor a5, a burner a6 and a solenoid valve box (not shown in the figure). shown), it can be seen from the figure that the travel switch assembly a3, the combined pneumatic actuator a4, the burner a6 and the electromagnetic valve box have very complicated structures, and the combustion efficiency is not high, which will occur when the cold furnace is ignited. Black smoke is emitted, which is difficult to meet the country's energy-saving and environmental protection requirements, and fo...

like figure 1 As shown, the existing conventional large oil gun burner includes an oil gun a1, an ignition gun a2, a travel switch assembly a3, a combined pneumatic actuator a4, an air distributor a5, a burner a6 and a solenoid valve box (not shown in the figure). shown), it can be seen from the figure that the travel switch assembly a3, the combined pneumatic actuator a4, the burner a6 and the electromagnetic valve box have very complicated structures, and the combustion efficiency is not high, which will occur when the cold furnace is ignited. Black smoke, it is difficult to meet the country's energy-saving and environmental protection requirements, and for explosion-proof occasions, solenoid valves, travel switches, etc. need to be explosion-proof, which is expensive and greatly increases the manufacturing cost of large oil gun burners
