Problems solved by technology

The essence is to use the pressure difference to reflect the change of the thickness of the material layer, which will be affected by factors such as the porosity and viscosity of the material layer. It can only reflect the thickness change indirectly, and there is a large error
And at the same time, because the pressure measurement belongs to the point measurement, the spatial distribution information about the fuel thickness cannot be obtained, and the thickness difference of the solid fuel material layer in each area cannot be distinguished.
Therefore, there are also great limitations in the actual application process.

Embodiment 1

[0049] The structure schematic diagram of the test device for combustion in this implementation is as follows: figure 2 As shown, it includes a burning solid fuel 1 , a common camera 2 and a computer 3 , and the computer 3 can also be a computing device integrated with the camera and has an image processing function.

[0050]The application scenario in this embodiment is the measurement of the thickness of the garbage material layer in the garbage incinerator. A grate type domestic garbage incineration power plant with a daily processing capacity of 400 tons is used as a specific application scenario. For domestic garbage that is being burned, the ordinary camera 2 is a furnace monitoring camera that takes pictures of the solid combustion in the furnace, and the computer 3 can access the images captured by the ordinary camera 2 and perform calculations on them. When the incinerator is running, the monitoring camera is normally operated, and the monitoring camera screen is fac...

Abstract

The invention relates to the technical field of combustion measurement, and specifically discloses a method for measuring the thickness of a solid fuel material layer in real time, comprising the following steps: (1) taking a solid fuel combustion image to obtain a combustion image; (2) converting the combustion image into a characteristic image; 3) Segment the feature image to obtain a binarized image; (4) Identify the position of the burning fire line in the binarized image; calculate the thickness of the fuel material layer according to the position of the fire line. The measurement method of the present invention is a non-contact real-time solid fuel thickness measurement method, which has no effect on the combustion process and low equipment cost. It is enough to use an ordinary camera for flame shooting, and it is not affected by the porosity of the material layer, and the thickness can be directly measured. , the method error is smaller, the robustness is better, and the spatial distribution of material layer height can be obtained, which is of great significance for the application in the field of high temperature combustion.

Description

technical field [0001] The invention relates to the technical field of combustion measurement, in particular to a method for measuring the thickness of a real-time solid fuel material layer. Background technique [0002] During the combustion process of solid fuel, due to the influence of the spatial characteristics of flame temperature, turbulence and combustion conditions, various parts of the material layer burn unevenly. The result of uneven combustion is that the thickness of the material layer of each part of the solid fuel is inconsistent. In scenarios such as thermal power generation, waste incineration power generation, etc. that require continuous supplementation of solid fuel to maintain combustion stability, the thickness measurement of the solid material layer is very important. If the distribution of the thickness of each part of the discharge layer can be measured, corresponding adjustments can be made according to the thickness of each part, so that the soli...
