文中找出了原来燃烧系统的不合理性，提出了合理的改造方案，消除了由于燃烧不稳导致炉膛爆炸和调峰幅度小的现象；通过对受热面及吸风机的改造，解决了汽温偏低问题。经过两年多的运行实践证明：１号炉燃烧稳定，调峰幅度加大，汽温达到额定值，提高了１号锅炉运行的可靠性与经济性。 In this paper, the unreasonableness of the original combustion system was found, and a reasonable reformation scheme was put forward to eliminate the phenomenon of furnace explosion and peak shaving amplitude caused by the instability of combustion. By revamping the heated surface and the suction fan, the temperature of the steam Low problem. After more than two years of operation, it has been proved that No. 1 boiler has stable combustion, increased amplitude of peak regulation, and the steam temperature reaches the rated value, which improves the reliability and economy of No. 1 boiler operation.
