摘　　要：壳牌气化炉现有工业生产规模应用的炉温控制方法主要有两种:一是传统通过监控气化炉水冷壁的饱和蒸汽量(F)来监控气化炉炉温;二是通过监控气化炉水冷壁出口水汽密度(ρ)及通过水汽密度计算的热负荷(J)来监控气化炉炉温。两种方法的基础是准确的仪表测量值(ρ)及(F)。实际运行过程中,由于ρ、F测量仪表无法在线校准,当测量仪表发生漂移时就会给工厂技术人员带来误判。本文基于壳牌气化炉运行原理,借助工程计算软件给出了蒸汽产量(F)和水汽密度(ρ)的相互校验模型;工业应用结果表明,应用该模型可在确定F和ρ中一个参数准确量的情况下即可模拟计算获得另一个参数值,与测量值进行对比与修正,达到正确监控炉温的目的。There are mainly two methods of furnace temperature control applied in the scale of current industrial production of Shell gasification furnace:Firstly,monitoring the temperature of gasification furnace through monitoring the quantity of saturated steam(F) traditionally,and secondly,monitoring the temperature of gasification furnace through monitoring the vapor density of water wall exit of gasification furnace(ρ) and thermal load calculated from the vapor density(J).The foundation of both methods is the accurate measured value of instrument(ρ) and(F).During the actual operation,due to that online calibration is not available in the measuring instruments of p and F,misjudgment will be brought to the technicians of plant if the measuring instrument is diven by the current.The article provides the cross-checking models of output of saturated steam(F)and vapor density(p) in virtue of engineering calculation software.The results of industrial applications show that another parameter value can be acquired from analog computation by the applications of this model under the situation of confirming one accurate parameter quantity within F and p,and the comparison and correction can be carried out with measured value to achieve the aim of monitoring the furnace temperature correctly.
