燃煤电厂输煤系统在运行过程中常出现堵煤和撒煤问题，严重影响电厂的安全稳定运行并增加维护成本。本文围绕该问题展开研究，分析堵煤与撒煤的主要成因，包括煤质变化、设备设计缺陷及运行管理不当等因素，并结合实际案例提出针对性的防治措施。通过优化输煤系统结构设计、加强日常巡检与维护、提升自动化监控水平等手段，可有效减少堵煤撒煤现象的发生，提高输煤效率与系统可靠性。研究成果对提升燃煤电厂运行管理水平具有现实意义。

Abstract

The coal handling system of coal-fired power plants often encounters problems of coal blocking and spillage during operation, which seriously affect the safe and stable operation of the power plant and increase maintenance costs. This paper focuses on this issue, analyzes the main causes of coal blocking and spillage, including factors such as changes in coal quality, equipment design defects, and improper operation and management, and proposes targeted prevention and control measures combined with practical cases. By optimizing the structural design of the coal handling system, strengthening daily inspection and maintenance, and improving the level of automated monitoring, the occurrence of coal blocking and spillage can be effectively reduced, and the coal handling efficiency and system reliability can be improved. The research results have practical significance for improving the operation and management level of coal-fired power plants.
