华塑锅炉规程第二版).doc

安徽华塑股份有限公司 热电厂 锅炉运行规程 批准：徐 鑫 审核：薛小超 编写：姚兴令 前 言 华塑热电厂一期2×300MW工程经过整组启动、试运行和顺利投产，遵循《电力工业技术管理法规》和《电业安全工作规程》的原则，结合产品设计说明书和300MW机组实际运行经验编写了本规程。 在编写过程中，尽可能地考虑了华塑热电厂机组的自动控制设计和LCD操作，力求做到操作程序准确并符合现场实际。但由于主、辅机设备及系统的部分资料缺少或不全，加上编者水平有限，难免存在不足之处。谨望生产过程中不断总结经验，逐步完善，同时也敬请使用本规程的运行人员、工程技术人员在学习和执行过程中提出修改意见，使本规程日臻完善。 本规程自颁发之日起正式试行，在执行过程中若发现与实际情况不符之处，以有关操作票执行为准，并将采用“规程修改补充通知”的形式予以修改补充，敬请注意。 目 录 第一章、锅炉主、辅设备技术规范及特性况···················1 1.1锅炉设备规范及特性····································1 1.2 锅炉设计规范········································4 1.3锅炉主要技术性能·····································8 1.4.锅炉辅助设备规范····································13 第二章、锅炉热工联锁、保护及试验························24 2.1热工联锁、保护试验通则······························24 2.2锅炉热工保护内容及试验方法··························28 2.3 锅炉辅机热工联锁保护试验··························30 第三章、锅炉保护及试验··································45 3.1 锅炉试验··········································45 第四章、机组自动控制····································54 4.1.AGC运行方式········································54 4.2机组控制系统········································60 4.2.1机炉协调控制······································60 4.2.2机组目标负荷及目标负荷变化率的设定················61 4.2.3 机组一次调频投入··································62 4.2.4 主汽压力设定······································62 4.2.5 锅炉跟踪方式下锅炉主控指令的形成··················63 4.2.6 协调控制方式下锅炉主控指令的形成··················63 4.2.7 锅炉主控·········································64 4.2.8 汽机主控··········································65 4.2.9 RUN BACK··········································65 4.2.10 煤主控···········································66 4.2.11 给煤机煤量控制···································67 4.2.12 磨煤机入口一次风量控制···························68 4.2.13 磨煤机出口温度控制·······························69 4.2.14 锅炉给水控制·····································69 4.2.15 锅炉过热蒸汽一级减温控制·························72 4.2.16 锅炉过热蒸汽二级减温控制·························73 4.2
