摘要： PROBLEM TO BE SOLVED: To prevent the clogging of coke in coke pushing work by estimating the load on the motor for the driving of a pusher ram. SOLUTION: The load applied to the ram-driving motor in the coke pushing work is estimated from the relationship between the load on the ram-driving motor and a carbon resistance index calculated from the carbon quantity on the furnace wall and the carbon quantity in the furnace top space estimated from the coal nature and the operating conditions of the furnace. When a high pushing load is estimated, the load is lowered by controlling the coal nature and the operation conditions to prevent the occurrence of the push clogging.

摘要： PROBLEM TO BE SOLVED: To estimate the thickness of carbon layer deposited on the inner wall of an ascension pipe of a coke oven and prevent the clogging of the ascension pipe. SOLUTION: The thickness of the carbon layer deposited in the ascension pipe of a coke oven is estimated in the direction of horizontal cross-section by using the water content of the coal, the volatile content of the coal, the addition ratio of oil to the coal, the quantity of coal charged in the carbonization chamber, the temperature, the dust-generation of the coal and the time lapsed from the charge of the coal and the occurrence of the clogging of the ascension pipe with the deposited carbon in one carbonization cycle is predicted by using the estimation. The dust generation of coal is estimated by using the index representing the crushing property of coal, the flow rate of gas, the index representing the particle size of coal, the water content of coal and the addition amount of oil to the coal. When the generation of the clogging of the ascension pipe during the carbonization process is predicted, the nature of the coal and the operation conditions are changed to suppress the deposition speed of the carbon.

摘要： PROBLEM TO BE SOLVED: To provide a method for effectively suppressing carbon sticking to the surface of bricks in a coke oven, capable of suppressing the amount of the stuck carbon generated on the surface of the bricks in a carbonizing room during the dry distillation of coal by spraying water into a space at the top of the coke oven during the dry distillation of the coal for controlling a humidity in the space at the top of the oven and at the base part of an elevated tube. SOLUTION: This method for suppressing carbon sticking to the surface of bricks at the inside of a carbonizing room in a dry distillation of coal in a coke oven is to effectively suppress the stuck carbon to the surface of the bricks in the coke oven by spraying supplied water 14 from a spraying nozzle 13 through a pipe 12 for passing water into a space 5 at the top of the coke oven during the dry distillation of the coal 4 for controlling the temperature of the space at the top of the oven 5 and the base part 11 of an elevated tube 2 at 789-850 deg.C. Further, the suppression of the amount of the stuck carbon can be confirmed by measuring the amount of carbon stuck to a piece of a brick 10 inserted from a first loading port 9, a third loading port 8 and a 5th loading port 7 into the space at the top of the oven 5 and from the side surface of the solid elevated tube 2 into the base part 11 of the elevated tube together with a thermometer 6.
