Embodiment 1
[0015] Taking the 75-hole 5.5m tamping coke oven gas fuel oven as an example, the whole furnace is equipped with 18 standard combustion chambers and 4 horizontal wall combustion chambers, and each standard combustion chamber is equipped with 8 standard vertical fire channels. See Table 1 for point settings.
[0016] Table 175 5.5m tamping coke oven temperature monitoring point settings
[0017]
[0018] There are 450 temperature monitoring points in the entire coke oven, 362 points on the top of the furnace, and 44 points on the lower machine and the coke side of the furnace. The collection frequency of most of the monitoring points is 5 minutes, and it is necessary to display the real-time status of the monitored data in real time, and at the same time perform complex analysis and processing on the collected data.

The invention has the advantages that the detection precision is high and the oven drying quality is improved.
Description
technical field [0001] The invention relates to the field of temperature measuring devices using thermoelectric elements, in particular to an automatic monitoring system for coke oven oven temperature. Background technique [0002] Coke oven, also known as coke oven, is coal coking equipment and the key to coking technology. The body of a modern coke oven consists of five parts: a foundation platform, a regenerator, a chute, a combustion chamber and a furnace roof, and is mainly made of silica bricks. Before the coke oven is put into production, it must be baked. The quality of the oven is very important for the stable production, high production and long life of the coke oven. During the drying process, there are different requirements for the heating rate according to the different stages of the furnace temperature. It usually takes about 2 months from room temperature to 800 °C, especially about 1 month from room temperature to 300 °C, and the temperature accuracy during...
