一、概述 焦炉集气管压力是炼焦过程中重要控制参数之一,其压力过高或过低,直接影响到炉体寿命和焦炭与煤气质量。我厂现有66型焦炉两座,由于该炉型是单集气管结构,两座炉集气管先汇集后再进入初冷器和鼓风机,并且炉孔数较少,使集气管压力成为一个多扰动、无规律、变化大、非线性的控制 First, an overview Coke oven manifold pressure is one of the important control parameters in the coking process, the pressure is too high or too low, a direct impact on furnace life and coke and gas quality. There are two 66 type coke ovens in our factory. Since this type of boiler is a single collector pipe structure, the two furnace collector pipes are collected before entering the primary cooler and blower, and the number of furnace holes is small, so that the pressure of the collector pipe becomes one Multi-disturbance, irregular, large changes, non-linear control
