Abstract

The invention relates to a real-time detection method of instability of flame in an industrial furnace, which comprises the following steps: acquiring a color picture of the point of the flame, and inputting the picture into a supervisory control computer; converting the color image into a gray level image firstly, and then, converting the gray level image into a digital matrix; computing the characteristic value of the digital matrix by using 0-1 test programs compiled in the computer to judge whether the flame has a chaos phenomenon or not; sending a command by a programmable logic controller according to the judged result of the step to enable a regulator to regulate oil mass and oil pressure to enable the flame to reach a chaos state, and regulating the sizes of electrically operated valves of oil mass and oil pressure by utilizing programs; and continuously carrying out judgment repeatedly, and controlling the whole combustion process. The control method is simple and easy and can be used for sensitively, quickly and reliably detecting the combustion condition in a combustion chamber in real time. The invention provides a reliable and practical control method for diagnosis and active control of combustion instability of combustion equipment such as power station boilers, industrial furnaces and the like.

Description

technical field

[0001] The invention relates to the technical field of real-time monitoring and process and safety control of industrial furnaces, in particular to a real-time detection and control method for combustion flame instability of industrial furnaces. Background technique

[0002] The combustion flame is the most direct reflection of whether the combustion state is stable. Unstable combustion will not only reduce thermal efficiency, but also generate noise and pollution. In extreme cases, it will cause fire extinguishing in the furnace. Improper handling will induce furnace explosion and cause industrial accidents. Therefore, whether the combustion state of the furnace flame is stable or not is directly related to the safety and economy of the boiler. The determination of combustion stability is an important characteristic quantity of the combustion effect of the furnace. Stable and uniform flame ensures strong and sufficient combustion, minimizes the number of fu...
