摘　　要：为提高我国可再生能源的消纳能力,开展深度调峰技术改造已成为燃煤机组未来的发展趋势。本文从提高锅炉低负荷稳燃能力、实现机组供热工况热电解耦、提高机组主辅机及其环保装置低负荷下设备适应性3方面出发,对燃煤机组深度调峰的主要运行和改造技术进行了汇总和探讨,以期为各电厂实施技术改造提供思路。建议开展低负荷下锅炉精细化调整和稳燃试验,根据试验结果和调峰需求,分别从锅炉、汽轮机、热控等方面进行深度调峰改造可行性研究,通过改造、调试、验收最终实现机组深度调峰安全、经济运行。In order to improve the consumption capacity of renewable energy in China, carrying out deep peaking transformation for coal-fired power plants has become a development trend in the future. This paper discussed the main operation and transformation technologies of deep peaking for coal-fired power plants from three aspects： improving the combustion stability at low loads, conducting thermoelectric decoupling under heating conditions, and improving the adaptability of main auxiliary equipments and its environmental protection devices at low loads, thus to provide ideas for technological transformation for power plants.
