2x600mw锅炉主要施工组织设计方案(编辑修改稿)内容摘要：

surface and pipe coil assembly works and flue/air ducting fabricating asembly works. b. 50t 汽车吊负责现场设备卸车倒运等工作。 . b. Truck crane of 50t shall be employed in equipments unloading in site. 4 置在锅炉 0m， 辅助进行炉膛内管排及 小件 的吊装。 c . winch shall be arranged in 0m, assisting furnace internals lifting and the lifting of some samll units. d. 劳辛格负责汽包吊装工作。 Standjack system will be used in steam drum listing works. (5) 施工电梯布置 service lift arrangment 为方便锅炉施工，在炉 一 侧 布置一施工电梯。 Sservice lifts shall be arranged in each side of the boiler. 2 锅炉本体钢架安装 Boiler steel structure erection 锅炉钢结构由顶板、柱和梁、垂直支撑、水平支撑等部件组成，顶板由主梁、次梁和小梁组成一个坚固的梁格，其四周有水平支撑，主梁端有垂直支撑。 Boiler steel structure consists of roof, column, girder, vertical and lateral supporting, while roof prising of girder, secondary beam, trabecula and forming a firm box. 钢架内侧柱为主要承重钢柱，外侧副柱则通过梁、水平支撑与内侧柱相连，以增加钢架的整体稳定性。 钢结构从前至后共有 6 排。 锅炉钢架的连接，采用高强螺栓和焊接相结合的方式，顶板和主梁与次梁之间，柱和梁之间，垂直支撑、水平支撑之间采用扭剪型高强螺栓连接，其余构件间采用焊接连接。 Internal pillars of the structure are designed for bearing, while the external pillars are designed to reinforce the entire stability of structure by connecting with girders, lateral supporting and internal pillars. There are 6 rows. Bolt and welding are employed in the connection of structure. 吊装方案 Hoisting plans 主吊机械选用一台 FZQ2020 圆桶吊，一台 CC1400 履带吊为附吊机械，圆筒吊布置于锅炉炉左 K、 L 间距锅炉本体外侧柱中心线 5 米处， CC1400 履带吊布置于炉的另一侧。 钢架各段本着由炉前至炉后、先主柱后辅柱原则分段吊装，即安装一段找正一段，验收本段钢架后对高强螺栓进行终紧。 钢架安装过程中相应段平台、楼梯、栏杆随之安装。 Main hoisting plants prise of an FZQ2020 cylindrical crane and CC1400 crawler crane (as auxiliary hoisting plants), the cylindrical crane shall be arranged at left side of boiller。
