<p>PROBLEM TO BE SOLVED: To provide a method and a device for determining net coking time of a coke oven, capable of determining relatively easily with accuracy, completion of dry distillation of coal in a coke oven chamber.SOLUTION: There is provided the method for determining net coking time of a coke oven for determining completion of dry distillation of coal in a coke oven. The dry distillation gas discharged from the coke oven chamber of the coke oven is subjected to sampling, for measuring density of the dry distillation gas, and at the time point when the density reaches to a threshold, completion of the dry distillation of coal, is determined.</p> |
