焦化固废高效利用的研究

Research and Practice of High-efficiency Utilization ofCoking Solid Waste

通过300kg小焦炉实验得出以下结论:依据目前京唐焦化煤质,1.5%以内除尘灰配煤炼焦,对焦炭CRI与CSR基本无影响。焦化除尘灰回配不仅提高了焦炭质量,同时也产生了良好的经济效益并满足环保的要求。

This paper draws the following conclusions through the experiment of 300kg small coke oven:According to the current Beijing-Tangtang coking coal quality,the dust ash within 1.5%is blended with coal for coking,and the high-temperature reactivity of coke has little effect on the strength after reaction.Coking dust ash not only improves the quality of coke,but also produces good lean benefits and meets the requirements of environmental protection.
