摘　　要：随着碳达峰、碳中和目标的提出,我国国内电源结构亟需调整,以消纳更多的绿电,传统火电机组面临着节能减排、适应深度调峰低负荷运行的压力。本文以北方某热电厂机组灵活性运行改造为依托,对中速磨直吹式制粉系统与锅炉低负荷运行的相互适应性进行理论计算,并与调试运行参数进行对比,提出存在的问题,以期对同类制粉系统满足锅炉低负荷运行需求的改造工作提供参考。With the goal of carbon peak and carbon neutralization,the domestic power supply structure of China needs to be adjusted to consume more green power.Traditional thermal power units are facing the pressure of retrofit to meet the demand of deep peak regulation.In this paper,based on the flexible operation retrofit of one thermal power plant,we carried out the theoretical calculation of low load operation condition of medium speed mill,and compared with the commissioning operation result,in order to provide reference for the evaluation and retrofit of similar pulverizing system to meet the low load operation demand of boiler.
