摘要
为研究武钢 7.63 m焦炉上升管余热利用工程实施的可行性,对 2#炭化室上升管根部和桥管处荒煤气温度进行连续在线检测.分析发现:上升管根部荒煤气温度在整个结焦过程呈现类似Z字型周期变化规律,最高温度发生在推焦前烧石墨阶段,达 1 300℃～1 400℃,整个结焦周期的平均温度约为 771℃;桥管处荒煤气温度仍保持较完整的周期性规律;7.63 m焦炉单孔炭化室荒煤气产量为 1 156.42 m3/h,一个结焦周期内单孔炭化室荒煤气可利用理论热量约 13.76 GJ,工程理论吨焦产汽量(1.6 MPa低压饱和蒸汽)为 108 kg.
Abstract
In order to study the feasibility of the waste heat utilization project of the riser of 7.63 m coke oven in Wuhan Iron&Steel Co.,Ltd.,continuous online detection of raw gas temperature at the root of the riser and the bridge pipe of the 2#carbonization chamber was carried out.It was found that the temperature at the root of the riser showed a similar Z-shaped periodic change rule during the entire coking process.The highest temperature occurred during the graphite burning stage before coke pushing,reaching as high as 1 300℃-1 400℃.The average temperature during the entire coking cycle was about 771℃.The temperature of the raw gas at the bridge pipe still maintained a relatively complete periodic pattern.And the raw gas production in a single carbonization chamber of a 7.63 m coke oven was 1 156.42 m3/h.The theoretical heat available for raw gas in a single carbonization chamber within a coking cycle was about 13.76 GJ,and the theoretical steam production(1.6 MPa saturated steam)per ton of coke was 108 kg.
