摘要： PROBLEM TO BE SOLVED: To provide a highly accurate method for controlling a water content of a raw material coal in a quality adjusting device of the raw material coal for a coke. SOLUTION: This method for controlling a water content of a raw material coal for a coke, is to input a value of the water content of the raw material coal measured before the charging port of an indirect heating type drying oven together with the temperature and the treating amount of the raw material coal, and a temperature of the dried coal at the discharging port of the drying oven, and calculate a necessary heat value in order to attain an objective value of the water content after drying for controlling a steam pressure supplied to the drying oven. Then, the value of the supplied steam pressure is corrected through a feed back control by comparing the water content attached to the dried coal with that of the objective value, and further the output of the feed back control is fuzzy-controlled.

摘要： PURPOSE:To provide the subject method capable of producing good-quality coke by uniformizing the bulk density of feed coal in a coke oven easily at low cost. CONSTITUTION:Feed coal C is imparted with a kinetic energy to apply a spiral falling impact force thereto by using a screw feeder 21, and this kinetic energy is made variable. That is, the feed coal C is fed, under revolution by the screw feeder 21, toward an outlet 31, allowed to fall via the outlet 31 upon a chute 24, and thus imparted with spiral motion through the chute 24; thereby, the feed coal C is allowed to fall spirally into a coke oven 1; concurrently, as the bulk of the coal C loaded is increased, the moving velocity of the coal C is raised.

摘要： PURPOSE:To provide an apparatus for confirming the attachment or detachment of an oven door of a coke oven and a confirmation method capable of realizing the reliability of each operation and promoting the automation of a traveling machine of a coke oven in the confirmation of the attachment or detachment of an oven door using a distance-measuring means such as an optical sensor attached to a traveling machine of a coke oven. CONSTITUTION:The distance between an operation mechanism part of a lifter and the oven door of a coke oven varies by the steps of the attaching and detaching operation of an oven door. Taking note of this phenomenon, the confirmation apparatus is provided with a distance-measuring means 21 capable of measuring the distance to the object site to be detected and with a controlling means to transfer the apparatus to the next operation step when the distance measured by the distance-measuring means 21 falls within the range of optimum standard distance.

摘要： PROBLEM TO BE SOLVED: To charge coal into a coke oven so that the level of the deposited pile of the coal charged from each hopper of a coal charging car into a carbonization chamber remain the same during the coal charging period. SOLUTION: The amount of coal cut out of each hopper of a coal charging car is occasionally weighed and compared to thereby determine the deviation of the amount of the coal flowed into a coal filling space located under each hole of a carbonization chamber corresponding to each hopper among the mutual coal filling spaces. A coal feeder of each hopper is controlled while correcting the amount cut out of each hopper according to the deviation. As a result, the level of the deposited pile of the coal in the coal filling spaces under each hole is made to maintain the same level and rise thereto during the coal charging period.

摘要： PURPOSE:To enable the promotion of the automation of a traveling machine for coke oven by placing an oven door posture recognizing apparatus in a coke pusher of a moving machine for coke oven or an oven door lifter (oven door detaching and attaching machine) of a guide vehicle. CONSTITUTION:An oven door posture recognizing apparatus, especially a telemeter 11 as the sensor of the apparatus is built in an oven door lifter 16 for the direct attaching and detaching of an oven door 4. As an alternative, the apparatus is provided with a gyration mechanism 13 capable of gyrating the telemeter relative to the oven door, a gyration angle detection part 21 combined with the gyration mechanism and an arithmetic unit to calculate and judge the detected posture value of the oven door based on the detected gyration angle transmitted from the gyration angle detection part 21 and the detected distance transmitted from the telemeter. These gyration mechanism 13 and the gyration angle detection part 21 are built together with the telemeter in the oven door lifter 16. The apparatus can dispense with the use of a moving mechanism and a turning mechanism for the detector such as a sensor in contrast to conventional apparatus. Accordingly, the apparatus necessitates decreased installation space, stabilizes the mounting part of the detection apparatus and contributes to the improvement of detection accuracy, simplification of accessory apparatuses, shortening of time cycle and reduction of cost.
