July 18, 2006 Lee January 1, 2008 Chen et al. Using this process, an amount of material within a particular size range, can be added to a bed of loosely charged coal, increasing the density of the bed without a significant impact on the volume occupied by the coal charge. With reference to Figure 16, three separate particulate size distributions are blended with one another to define the multi-modal bed of material 1600.
229910003726 AI2O3 Inorganic materials 0. At 304 a coking material is screened from a volume of coking material to a second particulate size. The present invention further provides methods of reducing the density of bulk materials. Multi-modal blends of the present technology, without oil addition, exhibited improved flowability characteristics in all experiments, compared with standard coal mixtures. A coal that achieves a low CRI value and a high CSR value, after coking, is most favorable in the market because these values relate to blast furnace performance and, specifically, fuel rate and permeability of the burden.
Coke chemistry, coke size, and coke strength stability have been considered the most important factors for evaluating coke for use in a blast furnace.
The attraction is strong enough to overcome the forces imposed by vibratory screeners. The higher density of the coal bed compounds on the flowability benefits. Machine-executable instructions include, for example, instructions and data which cause a general purpose computer, special purpose computer, or special purpose processing machines to perform a certain function or group of functions.

Any low cost method to improve coal density without stamp charging would have application in the United States to improve coke quality and possibly use some lower cost coals or coal substitutes.
Where neither the duration nor the quantity produced was explicitly stated on supporting documentation, the MATRIC team looked at similar runs and talked to people who actually conducted the experiments to obtain additional information.
High bulk density can cause hard-pushing and damage coke oven walls in a byproduct coke oven. The sole flue temperature control system temperature bias will be active in the automatic setting and inactive in the manual setting. These act as disturbances affecting the controlled variables.
The market for metallurgical coal is also dependent on the cost of transportation. In another embodiment, the bed of coke exhibited a stability level of approximately 55-67. The method of example 15, further comprising:•
Experimentation using an embodiment of the present technology was done where the fine material was pre-conditioned to be of low moisture content.
In this tumbler test the drum contains lifters that raise the coke and allow it fall so that it undergoes a large number of impacts with the drum walls.
According to a PCD for DJM-1725H, UCC produced 541,866 pounds of aim-grade and zero pounds of off-grade base resin.
