Border is severe, labor intensity of workers is big, thermometric human error is big, encounter the rainy day then can not thermometric, Control for Kiln Temperature lag is serious, causes
Furnace temperature fluctuation is big, and it is low to stabilize coefficient, and in order to guarantee coke quality, frequently with temperature upper limit control method, gas consumption amount is big.
Therefore, artificial thermometric is not able to satisfy coke oven automated production and energy-saving and environment-friendly demand already.
And by the consumption of coke oven automatic temperature measurement control system real-time measurement furnace temperature and feedback control coal gas, not only thermometric is quasi-
Really, in time, and the flow of coal gas can be adjusted in real time, reduce gas consumption, it meets the energy-saving and environment-friendly requirement in China, is future
The inexorable trend of coke oven automation computer heating control.
Currently, the automatic temperature measurement control of coke oven mainly has two major classes method: one kind is the installation S type at the top of coke oven regenerator
