Research on Dynamic Features of Sintering Waste Heat Recovery Power Generation of Double--pressure System

By analysing one of the three cycle ways of sintering heat in cogeneration system, taking the double--pressure system as an example,a mathematics and physics model of heat transfer has been set up on the basis of detailed analysing the features of the heat transfer process and construction of double-- pressure heat recovery steam generator （HRSG）,and then optimization model, static model and dynamic model of off design condition have been set up on the basis of the heat--transfer model. The dynamic pa- rameters of a narrow point of temperature,near--point temperature,and the hot end temperature are sepa- rately optimized to get the thermal parameters matching mater which enables the system at the best sta- tion. The results of research provide theoretical basis for controlling system and optimizing design of heat recovery steam generator.
