摘　　要：在某焦化厂焦炉煤塔下煤过程中,多次出现在煤嘴未关闭情况下,煤车开离受煤区域,造成煤塔漏煤,也多次出现煤车未在煤塔下方,煤嘴却自动打开造成漏煤,影响煤车正常作业,同时影响整个焦炉的正常出焦。针对该问题,对煤塔漏煤的原因进行深入分析,并从受煤关严信号、电气回路、程序、画面等多方面实施改进,从根本上解决了煤塔漏煤技术难题,保障了煤车作业的安全稳定性。During the coal unloading process of a coke oven coal tower in a certain coking plant,there were multiple occurrences where the coal nozzle was not closed and the coal truck drove away from the receiving area,causing coal leakage in the coal tower.There were also multiple instances where the coal truck was not below the coal tower and the coal nozzle automatically opened,causing coal leakage,affecting the normal operation of the coal truck and affecting the normal coke discharge of the entire coke oven.In response to this issue,an in-depth analysis was conducted on the causes of coal leakage in the coal tower,and improvements were implemented from various aspects such as strict coal control signals,electrical circuits,programs,and graphics,fundamentally solving the technical problem of coal leakage in the coal tower and ensuring the safe and stable operation of the coal truck.
