Title: Method for controlling coking chamber of coke oven
Inventor: KAMATANI KATSUNAMI
IPC: C10B29/06
Filed: 1980-12-03
Abstract: PURPOSE: To detect surely and rapidly damage to the wall of a coking chamber, by a method wherein smoke density exhausted from the combustion chamber of a coke oven is constantly measured, and the coking chamber charged with coal is detected when the smoke density becomes higher.  
     CONSTITUTION: Coal is introduced into the coking chamber 7 of a coke oven 1 at constant time intervals. Fuel and combustion air are supplied to the heating chambers 12a, 12b of a combustion chamber 8 and regenerators 10a, 10b at constant time intervals. Exhaust gas is passed through side flues 2, 3 and introduced into a main flue 4. Smoke density is constantly measured by a smoke density measuring means 6 composed of a projector 16 and a receptor 17 provided on the both side walls of the flue 4. The smoke density is recorded through an amplifier 18 by a recorder 19. When a partition wall 9 between the combustion chamber 8 and the coking chamber 7 is damaged, coke oven gas generated by coal which is dry-distilled in the coking chamber 7, is flowed into the combustion chamber 8 to cause incomplete combustion, and the smoke density in the exhaust gas becomes higher. This time is made to correspond to the time at which coal is introduced into the coking chamber 7, and the coking chamber 7 having damaged partition wall 9 is detected.
