Problems solved by technology

[0004] If there is a difference in the flow rate of pulverized coal in each pulverized coal pipeline, the heat load of the furnace will be unevenly distributed, and the center of the flame will be deflected, resulting in a series of problems such as unstable combustion and increased pollutant emissions.

Abstract

The embodiment of the invention provides a method and a device for measuring the velocity of pulverized coal based on image recognition, which is used for measuring the pulverized coal flow rate in apulverized air duct. The method comprises the following steps of: acquiring a first pulverized coal particle image at a first time and a second pulverized coal particle image at a second time in a target pipe; Performing image enhancement on the first pulverized coal particle image and the second pulverized coal particle image to obtain a third pulverized coal particle image and a fourth pulverized coal particle image; Performing a cross correlation operation on the third pulverized coal particle image and the fourth pulverized coal particle image to determine a target displacement between thethird pulverized coal particle image and the fourth pulverized coal particle image; Calculating a time difference between the first time and the second time; Determining a target flow rate of pulverized coal in the target pipe according to the target displacement and the time difference.

Description

technical field [0001] The invention relates to the field of thermal power generation, in particular to a method and device for measuring the flow velocity of pulverized coal based on image recognition. Background technique [0002] The flow rate of pulverized coal in the primary air powder pipe of the thermal power plant unit is an important parameter for the stable and economical operation of the boiler in the power plant. [0003] A reasonable and balanced pulverized coal flow rate is of great significance to the normal operation of power plant units. At present, there are many positive pressure direct blowing powder feeding systems in domestic thermal power boiler boilers, and the flow rate of pulverized coal in the primary air duct is directly related to the safety, stability, efficiency and environmental protection parameters of the boiler combustion system of the generating unit, especially For tangential combustion boilers with once-through burners arranged at four ...
