摘要： PROBLEM TO BE SOLVED: To provide a method for producing lump coal, with which lump coal with prescribed density and strength is stably produced.SOLUTION: The method for producing lump coal includes: a kneading step to knead fine powder coal and a binder and to generate a kneaded product; and a lumping step to lump the kneaded product, wherein in the kneading step the fine powder coal heated to 100 to 200°C is supplied to the inside of a kneading vessel 5, and moisture is supplied to the inside of the kneading vessel 5. It is preferable that the moisture is water vapor and temperature of the water vapor is not higher than +20°C, or not lower than -20°C compared with the temperature of the fine powder coal in the kneading vessel. It is preferable that the moisture is water vapor and a feed rate of the water vapor with respect to the fine powder coal is 0.3-20.0 kg/ton.

摘要： PROBLEM TO BE SOLVED: To provide a coal formulation method for producing coke that can exactly presume the strength of coke from blended coal including non- and slight-caking coal in no utilization of a caking parameter and can permit the increase in the formulation of the non- and slight-caking coal by utilizing the presumption method. SOLUTION: In the coal formulation for producing coke by discharging plural kinds of coal into a coke oven, the amount of the fraction of the non- and slight-caking coal in the formulated coal and the amount of a caking additive for attaining the target hot strength and the cold strength are adjusted so that its cold strength may reach the maximum value or the neighborhood of the maximum value.

摘要： PURPOSE:To suppress NOx concentration in a combustion exhaust gas and to increase a working efficiency by correcting a pattern of a predicted value of the NOx concentration in the residual period of the pattern set initially, on the basis of a difference from an average value of a measured value of the NOx concentration in a prescribed time before one period corresponding to the prescribed time. CONSTITUTION:An average value Xg of a pattern Na of NOx concentration in the past (t) minutes from the time T4 to T5 is determined and an average value Xc of the pattern NA of the NOx concentration for (t) minutes between the times 6 and T7 of a combustion period X before one combustion period is determined. Then, a difference Xf between these average values Xg and Xc is calculated. This difference Xf is applied to addition-subtraction correction of basic predictive patterns NAG and NBG of the NOx concentration from the current time T5 on and thereby predicted values NAY and NBY of the NOx concentration from the current time T5 on are obtained. According to this constitution, it is possible to suppress the NOx concentration in a combustion exhaust gas to a prescribed value or below while minimizing an adverse effect thereof on operation.

摘要： PROBLEM TO BE SOLVED: To provide a pulverized fine coal injecting method into a blast furnace in which the stable operation of a dry dust collector is continued and the increase of a fuel ratio is suppressed by preventing soot from being developed at the furnace top, even in case of incompletely burning the pulverized fine coal by injecting the large quantity of pulverized fine coals from a tuyere in the blast furnace. SOLUTION: In the method for injecting the pulverized fine coal together with hot blast from the tuyere in the blast furnace, combustible volatile matter content in the pulverized fine coal is adjusted correspondingly to oxygen quantity in the injected hot blast.
