干熄焦系统优化操作与控制

针对干熄焦系统的传热问题,建立了干熄炉内一维传热模型和干熄炉出口循环气体燃烧数学模型,并对其进行了离散化和仿真计算。结果表明,所建立的数学模型是正确的,可以作为系统仿真优化操作与控制基础。利用该模型的计算结果,找出了系统循环风量、导入空气量和锅炉蒸汽发生量之间的对应关系,可以对干熄焦系统的操作优化进行离线指导。

Optimum operation and control for CDQ system

Against heat transfer issue of CDQ system, one-dimensional heat transfer mode in CDQ chamber and math model of circulation gas combustion at the outlet of CDQ chamber were set up, and the discrete and simulation calculation was made on them.The result showed that the math model set up was correct, it can be used as system simulation optimum operation and control basis.By means of the calculated result of the model, the responding relationship among the system circulating air volume, air volume introduced and steam generation volume of boiler were found, which was used to conduct off-line guidance for optimum operation of CDQ system.
