Japan, Feb. 24 -- NIPPON STEEL CORP has got intellectual property rights for 'METHOD FOR PREDICTING GAS CALORIE OF COKE-OVEN GAS.' Other related details are as follows:
Application Number: JP,2020-069121
Category (FI): C10B57/00,C10B57/04
Stage: PROBLEM TO BE SOLVED: To provide a method for predicting gas calorie of a coke-oven gas that can accurately estimate the gas calorie of the coke-oven gas communicated in a steel mill in real time without actually measuring the gas calorie of the coke-oven gas for each kiln.SOLUTION: A method 10 for predicting the gas calorie of the coke-oven gas generated in a process of carbonizing coal in a coke-oven to produce coke includes: cumulative coal charge amount calculation step S1 for integrating a coal charge amount into a carbonization chamber of the coke-oven within a cumulative time from a predicted point in time to 30% to 70% of the carbonization time of the coal; and gas calorie prediction step S2 for predicting the gas calorie of the coke-oven gas at the predicted point in time by using the cumulative coal charge amount calculated in the cumulative coal charge amount calculation step and a conversion factor that can convert the cumulative coal charge amount into the gas calorie.SELECTED DRAWING: Figure 3 (Grant)
