1 引言近几年,燃油(气)贯流蒸汽锅炉已从直接进口国外贯流锅炉发展到引进国外技术在国内生产。然而,在实际使用过程中,锅炉运行仪2～3个月,就发生水管爆裂。由于贯流锅炉本身结构的特殊性.它的可维修性差,一般只能更换炉本体,因此给用户造成一些不必要的损失,同时也影响了贯流锅炉作为一种节能型锅炉在我国的推广使用。2 原因分析调查表明,问题主要出在用户水质管理上。目前国内配套贯流锅炉的软水器一般选用美国的AU-
1 Introduction In recent years, the steam (gas) steam turbine has been imported from foreign direct flow boilers to the introduction of foreign technology in the domestic production. However, in the actual use of the process, the boiler running instrument 2 to 3 months, the occurrence of pipe burst. Due to the special structure of the cross-flow boiler itself, its maintainability is poor, and generally it can only replace the furnace body, thus causing unnecessary losses to users and also affecting the promotion of the through-flow boiler as an energy-saving boiler in our country use. 2 Analysis of the Cause Investigation shows that the problem lies mainly in the user water quality management. At present, domestic water softener supporting tubular boiler generally use the US AU-
