通过燃烧器的综合改造，包括采取部分燃烧器下倾、反切，以及稳燃腔煤粉燃烧器的使用，解决了沙角发电总厂Ａ厂１号炉长期以来存在的飞灰可燃物偏高的问题，使锅炉热效率达到９１．３～９２．２％，超过设计值的１～２％。同时还解决了该炉过热器超温和烟温偏差过大的问题。
Through the comprehensive renovation of the burners, including taking part of the decanter and anti-cut burners, and the use of stable combustion chamber pulverized coal burners, the long-existing high combustibility of fly ash in furnace No 1 of Shajiao Power Plant A The boiler thermal efficiency reached 91.3 ~ 92.2%, exceeding the design value of 1 ~ 2%. At the same time also to solve the overheating superheater smoke temperature deviation is too large.
