摘　　要：论述了亚临界参数自然循环及控制循环锅炉的水动力特性与炉型结构、燃烧方式、锅炉容量及参数、运行方式等因素的关系。根据循环特性参数与水冷壁结构特性的函数关系，分析了６００ＭＷ级亚临界参数锅炉采用自然循环的基本条件。探讨了超临界参数锅炉的水动力特性及传热特性与工质热物理特性、水冷壁型式、运行方式的相关性。This paper expounds the relationship on water dynamic property and some factors of the subcriticalpressure parameter natual circulation boiler and the controlled circulation boiler. these factors comprise furnanceconstruction combustion pattern boiler capacity and parameters and mode of operation. Based on the functionalrelationship on circulation performance parameters, it analysises subcritical circulation pattern. It also discussessubstance thermal physics property water wall model and operation pattern of the supercritical pressure boiler.
