摘　　要：该文介绍利用动态数学模型，分析ＰＦＢＣ锅炉在异常工况下，水冷壁两侧压差的变化情况。根据仿真试验结果可知，如果锅炉出口处安装防爆片，且其排放量大于锅炉出口总烟气量的５０ ％ ，则当防爆片动作时，有可能引起水冷壁两侧压差超限。The paper discribes how pressure difference changes of PEBC boiler water wall, operating under abnormal conditions, may be analyzed with the help of dynamic mathematical models. Simulation tests show that in case blow out diaphragms, with a blow out capacity exceeding 50% the boiler's total discharged gas volume, are installed at the boiler's exit, an incidental blow out may effect pressere difference over the two sides of the water wall exceeding allowables.
