Abstract

The invention relates to a detecting device which is especially applicable to the detection on the excess air coefficient alpha value during the heating process of the coke oven, and the guide method on the adjustment of the heating cycle of the coke oven; the invention discloses a coke oven alpha value on-line detection system which comprises a gas analyzer and an alpha value on-line analysis module; the gas analyzer is arranged between a fume pipeline and a chimney; the fume with each gas content being analyzed is discharged after going through the chimney from the pipeline; the alpha value on-line analysis module is connected with the gas analyzer through a signal line; and the content data information of each gas analyzed by the gas analyzer is transferred to the alpha value on-line analysis module through the signal line to calculate the alpha value. The invention provides an on-line system to detect the alpha value of the coke oven, and a coke oven heating cycle adjustment method thereof, and can realize the alpha value on-line detection of the coke oven, promptly guide and improve the coke oven heating, and further accelerate the sufficient, comprehensive and reasonable burning of the heating gas. In a word, the invention has the advantages of simple structure, convenient preparation, easy installation, low cost, simple operation and good effectiveness.

Description

technical field

[0001] The invention relates to a detection device, which is specifically applied to the detection of the α value of the excess air coefficient during the heating process of the coke oven and the guidance method for adjusting the heating system of the coke oven. Background technique

[0002] Whether the combustion of coke oven heating gas is sufficient has a great impact on the energy saving and emission reduction of the coking plant. At present, no device or method for online detection of coke oven α value has been found at home and abroad. Most of them use manual detection of coke oven heating α value or only measure oxygen content. A small number of foreign and domestic manufacturers have adopted complex coke oven expert systems such as CCCS, ACCS (Japan, Baosteel), CPMS (Finland, Wuhan Iron and Steel) or CCMS (Wuhan Iron and Steel). Practice has proved that manual, hand-held detection and these expert systems only measure oxygen content and have the foll...
