Abstract

The invention relates to a method for measuring a horizontal angle of a nozzle of a four-corner tangential burner. The nozzle of the burner is provided with a reflective plate, the reflective plate isparallel to a plane in which the nozzle of the burner is, a light source is arranged at a position of an opposite angle of the nozzle of the burner, light emitted by the light source is reflected bythe reflective plate and then falls onto a first protective wall, a distance between a light falling point and a second protective wall is measured, and an included angle between the nozzle of the burner and the second protective wall is calculated through an arc-tangent function. The method for measuring the horizontal angle of the nozzle of the four-corner tangential burner measures accurately,is convenient to operate in the site, is easy to implement in the site, is simple and flexible, and is low-cost. The light source and the reflective plate are easy to obtain, and the arrangement is flexible.

Description

technical field

[0001] The invention relates to the field of thermal power generation, in particular to a method for measuring the horizontal angle of a nozzle of a four-corner tangential circle burner. Background technique

[0002] The burner is the main equipment of the boiler in the thermal power plant, and the four-corner tangential circle burner is a main structural form. Pulverized coal fuel and auxiliary air enter the furnace for combustion through the burners arranged at the four corners of the furnace. The horizontal angle of the burner is a key boundary parameter for forming the tangent circle and position of the air flow in the furnace, which will affect the combustion efficiency and the safety of the burner and the heating surface.

[0003] During the installation of the boiler infrastructure, the installation angle is measured by setting the line to the center of the furnace based on the base at the rear of the burner nozzle. However, it is generally not possibl...
