摘　　要：研究了3种不同的尾气处理方式对焦炭热反应性和反应后强度的影响,结果表明,尾气在炉盖处大火烧掉时焦炭热反应性最高,反应后强度最低;尾气导出用酒精灯烧掉次之;尾气放散时焦炭的热反应性最低,反应后强度最高。在相同的尾气处理方式下,热电偶冷端温度66℃时焦炭的热反应性高于36℃;热电偶冷端温度36℃和66℃的焦炭热反应后强度规律趋于一致。The influence of 3 different kinds of tail gas treatment modes on thermal reactivity and strength after reaction of coke was studied. The result showed when tail gas was burnt off, coke thermal reactivity was the highest, and the strength after reaction was the lowest, the burning of tail gas deduced with alcohol lamp was in the middle; when tail gas was bled, the thermal reactivity of coke was the lowest and the strength after reaction was the highest, Under the same tail gas treatment mode, when the cold end temperature of thermocouple was 66℃, the thermal reactivity of coke was higher than 36℃; the law of coke thermal strength after reaction of 36℃ and 66℃ of cold end temperature of thermocouple was tended to the same.
