Heat needed for heating destructive distillation, the adjustment of Lai Jinhang heating system in coking time as defined in a certain, mainly include temperature schedule,
Pressure regime and gas flow and the supply of air capacity etc..Since associated heat parameter and adjustment are mainly for bed rearrangement coke oven, refining
There is always the fluctuation of the production order and adjustment in burnt production process, the difference between combustion chamber is difficult to timely and effectively obtain, and occurs
Coke life or overdone phenomenon excessively when practical pushing coke operation, had both caused visual environment pollution and waste of fuel, and had also influenced coke matter
Amount.
Whether coking end time can be accurately controlled to be affected for coke quality.Coking end time generallys use manually at present
Determine:
(1) determine that fire is fallen according to the color of raw coke oven gas
At the same position of each carbonization chamber raw coke oven gas guiding system, a reserved fire with cover, which is fallen, determines hole.Fire is carried out to fall
It when judgement, takes off lid and escapes a small amount of raw coke oven gas, backlight detects by an unaided eye the variation of raw coke oven gas color.Before fire is fallen, the face of raw coke oven gas
Color is gradually faded away by dense yellow；Fire falls behind, and the color of raw coke oven gas is blue white.We by the color of raw coke oven gas by
What yellow was transformed into blue white is set in a flash " fire falls the moment ".
(2) determine that fire is fallen according to raw coke oven gas burned flame
At night and when can not see the color of raw coke oven gas clearly, the raw coke oven gas in tedge can also be ignited, be fallen through fire
Determine flame color when hole observation raw coke oven gas burning, is " fire falls the moment " at the time of flame switchs to transparent rice yellow.
