Abstract:

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.
