BJ—1型型焦连续焦结炉的研究

一、概述山西是我国的能源重化工基地,原煤产量已达到2.5亿t以上。但是随着机械化采煤工艺的发展,粉煤量迅速增加,占煤炭产量70％以上。每年积压、自燃及洪水冲刷的粉煤量达2000多万t,最高达到6000万t。因此,如何将粉煤加工转化为型煤、型焦,为冶金、化工、机械行业提供优质原料是个重要科研课题。阳泉是我国最大的无烟煤生产基地,粉煤积压严重。由山西省化工设计院、山西矿业学院、阳泉义井煤矿共同研制开发的BJ-Ⅰ型型焦连续焦结炉及BJ—Ⅰ型无烟粉煤型焦,于1989年12月通过了山西省科委。

废热式焦结炉进口废气温度分析

定性分析了废热式焦结炉焦结室温度分布规律，并根据热力学分析与计算讨论了温度对焦结过程的影响，解释了生产中存在的一些问题，指出进口废气温度偏高是目前焦结炉生产中返粉量大及换炉周期短的主要原因。

Effect of B2O3 addition on oxidation induration and reduction swelling behavior of chromium-bearing vanadium titanomagnetite pellets with simulated coke oven gas

The oxidation induration and reduction swelling behavior of the chromium-bearing vanadium titanomagnetite pellets (CVTP) with B2O3 addition were investigated. Besides, the reduction swelling index (RSI) and compressive strength (CS) of the reduced CVTP were also examined using the simulated coke oven gas (COG). The results suggested that the CS of CVTP was increased from 2448 to 3819.2 N, while the porosity of CVTP was decreased from 14.86% to 10.03% with the increase in B2O3 addition amounts. Moreover, the B2O3 mainly existed in the forms of TiB0.024O2 and Fe3BO5 in both CVTP and the reduced CVTP. Specifically, the CS of the reduced CVTP was elevated from 901 to 956.2 N, while the RSI was reduced from 5.87% to 3.81% as the B2O3 addition amounts were increased. Taken together, B2O3 addition would facilitate the aggregation and diffusion of metallic iron particles, which contributed to reducing the formation of metal iron whiskers and weakening the reduction swelling behavior.
