火道温度随结焦时间与换向时间变化规律的研究

Research on the change rules of flue temperature with coking time and reversing cycle

火道温度随结焦周期的变化呈双峰曲线变化规律,双峰曲线的两个波形随着推焦计划、检修时间与周转时间的不同而变化.通过对蓄顶温度与跨越孔温度随换向时间变化的测定与比较,选定蓄顶温度与火道温度的相关方程作为焦炉加热优化串级调控中的拟合火道温度.

The change of the flue temperature in a coking period is a hyperbola. Two undulances of the hyperbola change with the operating sequence,overhaul schedule and the direction changed period.The temperature changing principle of span hole and the temperature of the top of the regenerator in a direction changed period is measured and compared. So the relation equation of the flue temperature and the temperature of the top of the regenerator is used as simulative flue temperature in the otimized and series control system for the heating of coke ovens.
