Problems solved by technology

[0004] Disadvantages of the prior art scheme 1: 1. The workload of finding the hearth center is huge, mainly because it takes time and effort to set up scaffolding and diagonal corridors
2. Under the action of gravity, the steel wire will be bent and deformed, which cannot represent a strict straight line, resulting in deviation of positioning
3. It is also time-consuming to determine the center line of the burner nozzle, and it is easy to cause large human errors
[0006] The second disadvantage of the prior art solution: 1. Under the action of gravity, the steel wire connecting the spout and the rear wall of th

Embodiment Construction

[0026] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0027] Such as figure 1 As shown, the embodiment of the present invention provides a boiler burner tangent circle positioning tool, which includes a laser rangefinder 10, a leveling tool 20, a connecting component 30 and a level 40. The leveling tool 20 is located on the side of the laser rangefinder 10. The hard and straight outer edge of the leveling tool 20 is parallel to the axial direction of the laser rangefinder 10, and the inner edge of the leveling tool 20 is connected to the laser rangefinder 10 through the connecting part 30. connection. The level 40 is fixedly arranged on the laser rangefinder 10 or the leveling tool 20.

Abstract

The invention provides a boiler burner tangent circle positioning tool and method. The boiler burner tangent circle positioning tool comprises a laser range finder, a leveling tool and a level gauge,wherein the leveling tool is located on the side surface of the laser range finder, the straight outer edge of the leveling tool is parallel to the axial direction of the laser range finder, and the inner edge of the leveling tool is connected with the laser range finder through a connecting piece; and the level gauge is fixedly arranged on the laser range finder or the leveling tool. The beneficial effects of the invention are that the laser range finder is used for measuring the linear distance and replacing a steel wire commonly used in the prior art, a problem of positioning deviation caused by the bending deformation of the steel wire under the action of gravity in the prior art can be avoided, and the purpose of accurately positioning an imaginary tangent circle is achieved.

Description

Technical field [0001] The invention relates to a tangential positioning tool for a boiler burner and a positioning method. Background technique [0002] Tangential combustion is an important combustion organization type of boilers. Compared with swirl combustion, it has the advantages of simpler burner adjustment mechanism and stronger combustion stability. Therefore, it is widely used in coal-fired boilers in my country. The imaginary tangent circle radius is one of the key design parameters of tangential combustion, and the designed tangent circle radius should be strictly guaranteed when positioning the burner. Too large a tangent circle radius may cause problems such as slagging on the water wall of the furnace, while a too small tangent circle radius is not conducive to the ignition and burnout of pulverized coal. The burner installation specification stipulates the angle between the burner jet and the water wall on the horizontal section of the furnace. The deviation betw...
