1 建立和推广规范化、标准化修理改造 KZ(RS)型水火管锅壳式热水锅炉在运行中高温烟区管板经常发生裂纹失效。为了解决这个问题,各地进行了各种形式的修理改造,但实际效果不甚理想。目前该型锅炉虽已陆续停止生产,但其在全国的在役数量仍很可观,约十万余台,修理改造势在必行,因此要充分利用国内对高温管板裂纹机理的研究成果和一些成功的修理改造经验,用规范化、标准化管理修理改造工作,达到以尽可能少的费用,确实有效地解决数以万计的该型在役锅炉管板裂纹问题。
1 Establishment and promotion of standardization and standardization of repair and repair KZ (RS) type water and heat pipe boiler shell and hot water boiler in the operation of high temperature smoke zone tube plate often crack failure. In order to solve this problem, various forms of repair and transformation have been carried out all over the country, but the actual results are not satisfactory. At present, although the type of boiler has been stopped production, but its in-service number is still impressive, about 100,000 units, repair and transformation is imperative, it is necessary to make full use of domestic high-temperature tube plate crack mechanism research results and Some successful repair and transformation experience, with standardized and standardized management and repair work to achieve the minimum possible cost, indeed effectively solve the tens of thousands of this type of in-service boiler tube plate cracks.
