摘　　要：根据上海锅炉厂有限公司百万机组二次再热锅炉特点,提出了采用过热器、一次再热器和二次再热器串冲的稳压冲管控制的重点和难点,详细阐述该冲管方式中锅炉运行参数的合理控制,分析冲管系统中各点冲管系数和锅炉各级受热面中蒸汽吸热比例分配,为今后该类型锅炉稳压冲管提供借鉴和指导作用。According to the characteristic of first 1 000 MW boiler with double reheat cycles made by Shanghai Boiler Works Co. , Ltd. , the article gives the key points and difficulties of steady-pressure steam blowing where superheaters, primary reheaters and secondary reheaters are blown in sequence, and describes the reasonable control of boiler operation parameters using the method in detail, then analyzes the blowing coefficients of each point in the blowing system, as well as the heat-absorption distribution of each stage heating surface. The method is advisable and instructive to steady-pressure steam blowing of this type boilers in future.
