常规焦炉上的完全型煤炼焦

简单介绍了型煤炼焦技术在国内外的发展情况。分析了型煤炼焦的优点,包括提高了非主流炼焦煤种的利用量;在降低入炉煤水分的同时,缩短了炼焦周期,降低了焦粉产率。但型煤炼焦也存在诸多问题,主要包括炉型小且适应性差,炼焦过程中对环境的污染严重,产出的炼焦产品质量不稳定。为了解决上述问题,研究了常规焦炉上的完全型煤炼焦技术。介绍了该工艺的流程,重点分析了其经济意义与技术可行性。结果表明:完全型煤炼焦可以提高不粘煤的配入比例,从而直接提高焦炭产量。在降低入炉煤成本的情况下,提高了焦炭品质。

Complete briquette coking in normal coke oven

The advantages of briquette coking technology are analyzed after making a brief introduction about its development at home and abroad,such as sharply improving types of coking coal,some of them were not suitable for coking previously,shortening coking time,decreasing moisture of coking coal and coke powder yield.However,there are also some shortcomings,such as lower production capacity,poor coal adaptability,serious environmental polution and unstable product quality.In order to resolve those problems,research complete briquette coking in normal coke oven as well as its technical process.Emphasize its economic benefits and feasibility.The results show that this coking technology could improve proportion of non-caking coal,which is attributed to high quality coke and lower coking cost.
