摘要:

分析了立火道温度的分布规律,分析表明,立火道温度是加热煤气流量和两侧炭化室吸收热量共同决定的。对于5-2串序操作的焦炉,立火道温度的最低点在装煤后约5h闷炉后且另一侧炭化室的焦炭接近成熟的时刻。立火道温度的最高点在两侧的炭化室推焦前后。

Abstract:

The analysis of the distribution regularity of vertical flue temperature shows that the temperature of the vertical flue is determined together by the heating gas flow rate and the heat absorbed by the coking chambers on both sides. For the coke oven with 5-2 sequential operation, the lowest point of vertical flue temperature is at the time about 5h after the banking and the coke in the coking chamber on the  other side is near mature. The highest point of the vertical flue temperature is at the time before and after coke pushing from coking chambers on both sides.
