1.概述山东邹县电四期工程2×1000MW机组，第一台(#7)机组于2006年12月4日经过168小时试运正式移交电厂试生产。3030t/h锅炉是东方锅炉（集团）股份有限公司与日本巴布科克-日立公司及东方-日立锅炉有限公司合作设计、联合制造。锅炉为高效超超临界压力变压运行直流炉、一次再热、平衡通风、运转层以上露天布置、固态排渣、全钢构架、全悬吊结构Π型锅炉。锅炉配套安装6台沈阳重型机械有限责任公司制造的BBD4360型双进双出钢球式磨煤机，磨煤机为单侧驱动，采用一次风正压直吹式制粉系统。每台磨煤机配置两台上海成套所与上海重型机器厂合作设计生产的9224电子称重皮带式给煤机。磨制后的煤粉从磨煤机的两端经过外置式分离器分离后，合格的煤粉又通过8条ф480×10 mm一次风管道送入燃烧器（见图1）。考虑到单端及半侧磨煤机运行，从各磨煤机驱动动端引出的4条一次风管道均与#1、#2、#7、#8燃烧器相对应，从各磨煤机非驱动动端引出的4条一次风管道均为#3、#4、#5、#6，与相对应的8只燃烧器连接。

[Post=100]2.磨煤机的特性随着人们对双进双出球磨机的认识和了解，已经被越来越多的电厂所使用，虽然该磨煤机引进时间短，已经全部可以国产化。其结构及系统布置与其它形式的球磨机有很大的不同，设备比较先进而又复杂。从设备构造以及通过试运行，将所发生的问题进行汇总分析探讨。2.1双进双出球磨机的特点双进双出（BBD）钢球式磨煤机适用于所有煤种，对可磨系数与磨损指数没有任何限制，尤其适合磨制高磨损指数而挥发份也高的煤种。该磨对煤种变化的适应能力强，对“三块”不敏感，可将煤粉磨制得很细，且煤粉细度均匀性好。连续运行周期长，设备可用率高，耐磨性能好，检修工作量小。比单进单出钢球式磨煤机出力大，电耗低、运行可靠、自动化程度高等优点。其主要缺点是设备相对复杂，价格贵，运行电耗及钢材消耗量高，占据空间大等。磨煤机技术性能、参数见表1。附表1               双进双出磨煤机技术性能、参数<div align="center"><table class="MsoNormalTable" cellspacing="0" cellpadding="0" border="1" style="BORDER-RIGHT: medium none;

[Post=100]2.8密封风、吹扫风系统在锅炉零米安装有制粉系统密封专用的增压风机，2台100%容量的密封风机组成的密封风系统，以免在锅炉负荷变化时，密封气源压力受到一次风压力波动的影响。风机入口的风有一次风机出口冷风管道提供，风机出口的设计压力为14kPa。密封风系统包括下列两部分：磨煤机大齿轮保护罩密封风系统；密封风进入磨煤机大齿轮保护罩，出口压力0.4kPa，流量800m3/h。磨煤机密封风系统；在“V”形分配箱与磨煤机空心轴之间的动静结合部位设计有一密封盒，采用机械密封。为防止煤粉从磨煤机空心轴与分配箱空枢管之间吹出，从密封风母管引出密封风，密封风压力高于磨煤机内部压力4KPa。每台磨煤机各部位所需的密封风量：空心轴密封盒密封风量4375 m3/h，煤粉关断阀关闭时风量450 m3/h，打开时风量46 m3/h。螺旋输送装置轴承的密封风风量410 m3/h。同时向给煤机提供密封风。该磨煤机专门设计有吹扫风系统，吹扫风从冷一次风母管引出，当磨煤机投入或停用时，该系统设计有自动吹扫程序。吹扫风的作用主要是对一次风管道内进行吹扫，防止一次风管道内煤粉沉积堵管。2.9磨煤机油站及润滑油系统一台磨煤机安装五座油站，共有9台油泵（见表2）。大大提升了设备的安全性能。由于该磨煤机10000V超高压1700KW的电机轴承采用滑动轴承，专门设计了电机油站。以往磨煤机盘车装置主要在设备检修或者长时间停运为了确保所有润滑部件都覆盖上油以防止氧化时操作。现在运行中停止磨煤机后，如果磨内存有大量煤粉，也可以用盘车转动，以避免磨内起火，如果因为故障磨煤机跳闸罐内有煤时，为防止煤气化、燃烧或在煤层表面形成厚而硬的煤层，可盘使用车，因此盘车的重要性提高了，所以增设油站。三期磨煤机变速箱采用钢板焊接而成，由于变速箱内没有安装冷油器，所以箱内油温较高，长期运行会引起润滑油油质恶化，夏季高温时段温度通常在80℃以上，使齿面产生点蚀现象，因此增加油站采取强制润滑。大齿轮和小齿轮的开式齿轮润滑，仍沿用以往喷嘴中用压缩空气雾化自动喷射原理。GDZ-LZ63 高低润滑油站为磨煤机五座油站中最大的主油站，共有4台油泵，2台高压顶轴油泵，当磨煤机启动前首先启动该油泵，利用顶轴油泵建立起的25MPa油压，将磨煤机空心轴至少抬起0.038mm高度。2台润滑油泵，对大瓦采用油雾喷淋润滑。附表2                    磨煤机各油站参数<div align="center"><table class="MsoNormalTable" cellspacing="0" cellpadding="0" width="605" border="1" style="BORDER-RIGHT: medium none;
