摘要(Abstract)：

目前国内设计有侧墙、后墙给煤系统的大型循环流化床（CFB）锅炉在实际运行过程中普遍存在着给煤延迟与给煤不均匀的突出问题。通过对大型CFB锅炉机组给煤延迟问题和现存给煤系统运行特点的分析，提出了大型CFB锅炉给煤线路给煤延迟问题量化计算方法，并针对某超临界600 MW CFB锅炉给煤线路案例进行计算，获得了宽负荷快速调峰工况下给煤线路的给煤延迟特性。计算结果表明：给煤延迟问题在大型CFB锅炉机组的变负荷运行过程中普遍存在，均会导致一定程度的给煤不均情况；机组变负荷幅度、变负荷速率以及单给煤线路上给煤口数量均与给煤延迟问题的严重程度成正相关关系。计算方法与分析结果可为大型CFB锅炉给煤线路适应宽负荷快速调峰运行提供设计依据和技术参考。
