6、时有章可循、规范统一，确保除灰除渣系统安全、稳定、经济地投入运行。本标准由中国电力企业联合会提出。本标准由电站锅炉标准技术委员会归口并负责解释。本标准起草单位:苏州热工研究院有限公司。本标准主要起草人:季程馄、章旋、赵林峰。DL/T894一2004除灰除渣系统调试导则1范围本标准规定了火力发电厂除灰除渣系统启动调试的内容和方法。本标准适用于单机额定容量为125MW及以上燃煤火电机组的新建、扩建和改建工程中除灰除渣系统的调试。单机额定容量125MW以下的燃煤火电机组的除灰除渣系统的调试可参照执行。2规范性引

7、用文件下列文件中的条款通过本标准的引用而成为本标准的条款。凡是注日斯的引用文件，其随后所有的修改单(不包括勘误的内容)或修订版均不适用于本标准，然而，鼓励根据本标准达成协议的各方研究是否可使用这些文件的最新版本。凡是不注日期的引用文件，其最新版本适用于本标准。DL/T748.7火力发电厂锅炉机组检修导则第7部分除灰渣系统检修DL/T748.9火力发电厂锅炉机组检修导则第9部分干输灰系统检修DUT775火力发电厂除灰除渣热工自动化系统调试规程系统调试目的与内容系统冷态调试3.1.1冷态调试目的系统冷态调试在

8、除灰除渣系统单机试转结束后进行。系统冷态调试是为了验证除灰除渣系统中各设备动作正确可靠，系统运行正常，充分暴露并及时处理系统及设备存在的缺陷，为系统热态调试作好准备。3.1.2冷态调试内容系统冷态调试应完成以下内容:a)系统及设各检查;b)控制设备受电检查;c)阀门开、关状态检查;d)单个设备启停操作;e)连锁、报警值初步设定;f)各个子系统试运行;9)整套除灰除渣系统试运行。3.2系统热态调试3.2.1热态调试目的系统热态调
