锅筒锅筒drumgUOtong锅筒(drum)水管锅炉中用以进行汽水分离和燕汽净化，组成水循环回路并蓄存锅水的筒形压力容器，又称汽包。主要作用为接纳省煤器来水，进行汽水分离和向循环回路供水，向过热器翰送饱和燕汽。锅筒中存有一定水量，具有一定的热量及工质的储蓄，在工况变动时可减缓汽压变化速度，当给水与负荷短时间不协调时起一定的缓冲作用。锅筒中装有内部装工，以进行汽水分离、蒸汽清洗、锅内加药、连续排污，籍以保证燕汽品质，见图。锅筒是锅炉中最笨重且价格昂贵的厚壁承压部件。锅筒不但承受很高的内压，而且由于运行工况变化，还会由于壁温的波动产生热应力，因而工作条件恶劣，需进行有效的运行工况监督。结构和材料锅筒工作条件复杂，出现事故的后果严重，必须严格控制锅筒所用材料的化学成分、机械性能和焊接与加工工艺质量，并经过一系列的严格检验。铜筒由筒体和封头构成.(1)筒体:指锅筒的圆筒部分，它的内径和长度与循环方式、锅炉容量、蒸汽参数及内部设备结构形式有关。锅筒筒体通常在多辊筒卷板机上卷制而成.亚临界压力锅炉锅筒筒壁太厚，需在巨型压力机上压制.(2)封头:亚临界压力锅炉常为半球形，高压、超高压锅炉常为椭球形，中压锅炉为较扁的椭球形，封头上设有人孔，以便安装和检修内部装!。封头在水压机或油压机上压制成型。各种参数锅炉常用锅筒尺寸及材料见表。各种价傲锅炉常用拐筒尺寸及材料┌──┬────┬────┬──────┬──────┐│压力│中压│高压│超高压 │亚临界 │├──┼────┼────┼──────┼──────┤│内径│1400~│1 600│1600~1800│1700~1800││(mm)│ 1 600 ││││├──┼────┼────┼──────┼──────┤│壁厚│46 │90~100 │100~120 │140~200 ││(mm)│││││├──┼────┼────┼──────┼──────┤│材质│碳钢│C一Mn钢 │Mn一Ni一Mo钥│ C一Mn钢│││││Mn一Mo一V钢 │Mn一Ni一Mo钢│└──┴────┴────┴──────┴──────┘工况监督在锅炉起停过程中，锅筒上下壁及内外壁之间均有一定温差，产生热应力，特别是高参数锅护拐筒壁很厚，锅筒往往成为限制起动速度的主要部件，因此必须对锅筒内外壁及上下壁温差进行测t并加强监督。
