摘　　要：随着国内发电量的快速增长,火电机组常被要求在低负荷下运行。此时,锅炉需加入易燃燃料进行助燃,造成燃料成本升高。因此,采取相应措施,确保锅炉的稳定燃烧变得尤为重要。分析了机组热力系统在相同负荷下,研究了解列加热器后,对机组锅炉燃煤量的影响。通过解列不同的加热器,为确保锅炉的稳定运行提供参考。The thermal power units usually had to operate under low load for the changes of supply and demand in the domestic electricity market. In this situation, some combustible fuel had to be used to keep steady combustion of boiler, resulting in higher fuel costs and an increased MFT likelihood. This page started from thermal system, searching the influence of heaters step-out on the coal quality of boiler under low load, providing the reference of ensuring steady combustion of boiler by stepping out different heaters under low load.
