级喷水减温器，尾部设两级省煤器和一、二次风预热器。设备简介：1）锅筒锅筒内径为1500mm，壁厚为46mm 筒体全长10566 mm，筒身由20g 钢板卷焊而成，封头是用同种钢板冲压而成。锅筒内部装置由旋风分离器、顶部分离板、连续排污管、加药管等组成。旋风分离器直径为290，共40只。由旋风分离器出来的蒸汽穿过上部波形板箱，再经锅筒顶部波形板分离器箱，然后由蒸汽引出管到过热器系统。在锅筒顶部布置有波形板分离箱做为细分离，并在波形板分离器下装有12 根水管，把分离箱中带进的水分再送回锅筒的水容积之中，以保证蒸汽品质。在集中下降管进口处布置了十字挡板，消除下降管带汽及抽空现象，锅筒上除布置必需的管座外，还布置了再循环管座，吹灰管座，备用管座。为防止低温的给水与温度较高的锅筒筒壁直接接触，在管子与锅筒筒壁的连接处装有套管文档编码:CJ4M1M7J1V4 HT3Q6X3V10Z4 ZI9O9E9H2J2文档编码:CJ4M1M7J1V4

处，最高、最低安全水位距正常水位为上下各75mm。锅筒装有两只就地水位表，此外还装有两只电接点水位表，可把锅筒水位显示在操作盘上并具有报警的功能。另外，锅筒上配有备用水位管座，用户可用于装设水位记录仪 表 水 位 冲 量 等 仪 表，可 实 现 对 水 位 的 自 动 控 制、自 动 记 录。为提高蒸汽的品质、降低炉水的含盐浓度，锅筒上装有连续排污管和炉内水处理用的加药管，连续排污率为2。锅 筒 通 过 两 套 悬吊 装 置悬 挂 于 钢架 上，可 沿 轴向 自 由 胀缩。2）水冷系统炉壁、炉顶均由膜式水冷壁组成，通过水冷上集箱上吊杆悬挂于钢架上。炉膛横截面为39727750mm 2；炉顶标高为31380 mm，膜式水冷壁由605 和 6 45 mm 扁钢焊制而成。燃烧室为605的膜式壁管组成，其上焊有销钉，用以固定耐火材料。燃烧室上部与炉膛膜式水冷壁相接，下部与水冷风室及水冷布风板相接。水冷风室由膜式水冷壁钢管组成，内焊销钉以固定耐火材料。水冷布风板由60的钢管及6 45 扁钢组焊而成，在扁钢上开孔与钟罩式风帽相接。为了增加受热面，使锅炉有一定的超负荷能力，在炉膛内增加3 片自然循环的翼形水冷壁，每片水冷壁由16 根 60的钢管及6 20.5 扁钢组焊而成，为减小锅炉管子磨损，整体弯头由耐磨浇筑料防护。除翼形水冷壁外，炉膛部分分成左、右、前、后四个水循环回路，引汽管由1336组成及 1084.5钢管组成，集中下降管由5 根 27312钢管组成，在每隔集箱装有排污阀门以便定期排污。为了降低返料温度，降低炉墙重量，缩短起炉时间，增加密封信及运行的可靠性，设置了两个水冷旋风分离器。水冷旋风分离器有以下特点：1、耐火材料用量降低，从而使锅炉承重减轻，用户耐火材料费用减少。2、锅炉启动时间明显缩短。3、与炉膛相对膨胀量减少，增加了密封的可靠性。4、锅炉本体耗钢大幅增加。但用户成本降低明显。每个分离器由120 根 515 管子和上下两个环形集箱焊接而成，管子上焊有销钉以敷设高强度耐火浇筑料，整个分离器有上集箱支吊向下膨胀，下集箱与固定料腿设有膨胀节以保证密封。旋风分离器内衬采用耐磨、隔热材料。耐磨、隔热材料不修补的运行周期为二年，二年后每年的更换量不超过总重量的5%在锅炉正常运行的条件下，环境温度为27时，旋风分离器外表面温度不大于50，当环 境 温 度 大 于27 时，旋 风 分 离 器 外 表 面 温 度 允 许 比 环 境 温 度 高25 。旋风分离器下端回料立管结构合理，确保分离效果，并避免噎塞或气流扰动影响分离效果。旋风分离器上部烟气出口即中心筒采用耐磨耐高温材料制造，出口管延长进旋风分离器筒体一定长度以阻止烟气短路。以上所用钢管材料均为20GB30871999）无缝钢管。3）过热器本锅炉过热器分II

器畅通、降低循环灰在返料器内的再燃率，同时在分离器处布置水冷系统，以降低循环灰温度。每个水冷套由管子和上下两个环形集箱焊接而成，管子上焊有销钉以敷设高强度浇注料，整个水冷套由下集箱支撑在返料器耐火材料上整体向上膨胀，上集箱与锥体固定耐火 材 料 处 设 有 膨 胀 缝 且 上 集 箱 引 出 管 与 护 板 设 有 膨 胀 节 以 保 证 密 封。燃烧后的灰渣，较大颗粒可经炉底4 个 159 的冷灰管排走，而较小颗粒可以从旋风分离器下的返料器的细灰管排走。本 炉 为 床 下 动 态 点 火，在 风 室 后 侧 布 置 点 火 器，点 火 用 油 为0 轻 柴 油，油 压 为2.45Mpa。6）炉墙由于采用膜式水冷壁，炉膛部分采用敷管轻型炉墙，旋风分离器、斜烟道、炉顶和尾部烟道 用 耐 火 砖 或 耐 火 混 凝 土 和 保 温 层 砌 成，其 重 量 分 别 通 过 钢 架 传 到 基 础。考虑到炉墙受热后的膨胀，对于炉墙面积较大的部分及其接合处设有膨胀缝，为了保证炉墙金属及浇注料安全运行，炉墙升温和降温速度应控制在每小时100150 之间。7）锅炉管路锅炉采用单母管给水，锅炉给水通过操纵台，然后进入省煤器，从省煤器出口集箱出来后，由汽包给水管引入汽包。在汽包和省煤器之间装有不受热的再循环管，为保证锅炉点火启动和停炉冷却过程中省煤器内水的流动，在点火和停炉过程中不向汽包进水时，开启再循环管路上的阀门，这时由于 省 煤 器 管 内 水 温 较 高，而 产 生 自 然 循 环，使 省 煤 器 管 子 得 到 冷 却。在汽包上装有连续排污管，在各水冷壁下集箱分别装有定期排污管，在各需要疏水的部位还装有疏水用的阀门和管路。8）锅炉脱硫锅炉在燃用含硫量较高的燃料时，脱硫是通过炉前螺旋给煤机向炉内添加02 mm 的细粒石灰石来实现的现由燃料添加），由于本燃烧系统采用低温燃烧，该温度区对脱硫最有利。细粒石灰石在高流化风速下在整个炉膛内与烟气充分混合接触，又经分离器和返料器多次循环利用，石灰石利用率高，脱硫效率高。煤中所含硫分在燃烧后被固化在炉渣中，随炉渣排出。锅炉采用露天布置，运转层高为7M，锅炉标高从零M 算起，锅炉的构架全部为金属构架。3、主要参数：额定蒸发量130t/h
