METHOD FOR PREDICTING SIZE OF COKES

摘要

The present invention relates to a predicting method of cokes size which comprises: a step of measuring single coal kind inert ingredient which measures the inert ingredient (TI) by groups of coal kinds; a step of calculating weighted average of the inert ingredient (TI) of the coal blend which comprises by mixing the coals; a step of measuring the cokes size after dry distilling the coal blend; a step of deriving a correlation between the sizes of the cokes which is measured in the step of measuring the cokes size and the weighted average of the inert ingredient of the coal blend which is calculated in the step of calculating thereof; a step of predicting the cokes size from the correlation which is derived from the step of deriving a correlation. The present invention has an advantage of improving and maintaining the quality of cokes by predicting a quality of the cokes. [Reference numerals] (AA) Cokes size (mm); (BB) Cokes size= -0.383 誇(W_i � TI_i) + 67.7 R^2 = 0.834 wherein, W_i = single coal kind mixing ratio, TI_i = single coal kind inert ingredient; (CC) Weighted average of the inert ingredient of the coal blend
