【摘要】 为防止水冷壁散管腐蚀破坏 ,需要对其采取防护措施。在对原防护结构破损脱落原因探讨基础上 ,提出了 2 0 0 8t/h锅炉水冷壁散管新的防护结构设计方案 ,并研制了HCG特种混凝土防护材料。通过采用防护材料、预留膨胀缝、丝网加固、固定件连接焊接等技术措施 ,累计 36 0 0h的运行结果表明 ,该结构设计合理 ,防护材料完整 ,无脱落变形 ,对水冷壁散管起到了有效的防护作用。更多还原

【Abstract】 In order to prevent the corrosive destruction of waterwall separate tubes, it is necessary to adapt protection measures for them. Based upon the exploration on the causes of breakage and drop of original protection structure, a new protection structure design scheme for 2 008 t/h boiler waterwall separate tubes is put forward, and the HCG special concrete protective materials had been researched. Through adapting new protective materials, reserving expansive seams, reinforcing with silk screen, connecting firmwares by welding and other technical measures, the running result of 3 600 h. shows that, such structure design is reasonable, the protective materials are integral and without drop or deformation, so it acts effective protection on the waterwall separate tubes.更多还原
