Embodiment 1

[0015] Example 1, such as figure 1 , 2 As shown, a micro-oil pulverized coal burner includes an elbow 10 with a pulverized coal inlet and a connected primary air pipe 9, and a micro-oil oil gun 1 and a central cylinder 8 are arranged in the center of the primary air pipe 9 in sequence. At least one telescopically movable condensing body 5 is arranged on the outer wall of the micro oil gun 1 , and at least one telescopically movable guide ring 6 is arranged on the inner wall of the primary air duct 9 .

[0016] The structure of the telescopic movable condensing body 5 is that the condensing body is connected to the inner pull rod 2, and can be pushed or pulled out manually or automatically by an actuator. The structure of the telescopically movable guide ring 6 is that the guide ring is connected to the outer pull rod 3, and can be pushed or pulled out manually or automatically by an actuator.

[0017] The sectional shapes of the condensate body 5 and the guide ring 6 are tri...

Embodiment 2

[0018] Embodiment 2, a micro-oil pulverized coal burner, in order to ensure that the air-powder mixture outside the central cylinder 9 can enter the central cylinder, and cool the inner wall, protect the wall surface of the central cylinder, and prevent the occurrence of high-temperature burning. Also offer air film tuyere 7 on. All the other are with embodiment 1.

Embodiment 3

[0019] Embodiment 3, a micro-oil pulverized coal burner, in order to reduce the erosion and erosion of the coal powder on the micro-oil gun, an anti-wear plate is also provided at the lower part of the micro-oil gun in the elbow.

[0020] Working principle of the present invention: as figure 1 As shown, when it is in the micro-oil ignition mode, manually or the actuator action pushes the pull rod connected to the guide ring, so that the guide ring is located at the front end of the primary air duct. Manually or with the action of an actuator, the pull rod connected to the condensate is pulled, so that the condensate retreats to the rear of the oil gun tube. When the primary air powder mixture enters the primary air pipe from the elbow, it is guided by the condensate and the guide ring. Concentrated pulverized coal is led into the central guide cylinder and gathers around the outlet of the oil gun combustion cylinder, so that the high-concentration air-powder mixture is conduci...

Abstract

The invention provides a micro oil pulverized coal burner, which comprises an elbow joint provided with a pulverized coal inlet and a primary air pipe connected with the elbow joint, wherein the center of the primary air pipe is provided with a micro oil doper and a central cylinder in turn; the outer wall of the micro oil doper is provided with at least one condensation body which can telescopically move; the inner wall of the primary air pipe is provided with at least one guide ring which can telescopically move; the central cylinder is also provided with an air film wind opening; and the structures of the condensation body and the guide ring which can telescopically move are that: the condensation body is connected with an inner pull rod, the guide ring is connected with an outer pull rod, and the inner and the outer rods can be pushed in or pulled out manually or automatically pushed in or pulled out by an actuator. Because the outer wall of the micro oil doper is provided with atleast one condensation body which can telescopically move, and the inner wall of the primary air pipe is provided with at least one guide ring which can telescopically move, the internal structure ofthe burner can be changed according to operating conditions; under the states of micro oil ignition and normal combustion, different concentration distribution requirements of the pulverized coal aremet; and the micro oil pulverized coal burner is used for the oil saving ignition start and the low-load stable combustion in pulverized coal fired boilers in large-sized power stations.

Description

technical field [0001] The invention relates to a pulverized coal burner, in particular to a pulverized coal burner with micro-oil. It can be used for fuel-saving ignition and low-load stable combustion of large-scale pulverized coal boilers in power stations, and can also be used for burners in normal operation of power station units. Background technique [0002] Micro-oil ignition system is a very effective and practical pulverized coal boiler ignition and fuel-saving technology that has emerged in my country in recent years. The fuel-saving effect of this technology can reach more than 90%, and it has the outstanding advantages of less initial investment, wide adaptability of coal types, simple system, convenient operation, and less maintenance workload. The use of this fuel-saving ignition technology can greatly reduce the oil used for ignition and combustion in coal-fired thermal power plants, reduce power generation costs, and create huge economic and social benefits...
