目前火电厂低负荷调峰相当普遍，因此造成锅炉燃烧不稳、效率下降、燃油量增加等一系列问题。所以提高锅炉的调峰能力已成为节能降耗的当务之急。从燃烧器及其配套等方面的改造介绍670t／h无烟煤锅炉的稳燃与节油情况，实践证明该改造是成功有效的，节能效果显著。 At present, the load shedding of thermal power plants is quite common, resulting in a series of problems such as unstable boiler combustion, decreased efficiency and increased fuel consumption. Therefore, improving the boiler’s peak shaving ability has become a top priority for energy saving. From the aspects of burner and its accessory transformation, the steady burning and fuel saving of 670 t / h anthracite boiler are introduced. The practice proved that the reform is successful and effective, and the energy saving effect is remarkable.
