摘要：目前我国供暖行业普遍采用较大容量锅炉的集中供暖系统。实践表明，由热水锅炉、外网及楼房组成的封闭的循环系统里存在着大量的水渣，其危害已相当严重地影响了安全可靠的供暖运行。无论是对水管锅炉或烟火管锅炉，常造成水冷壁管堵塞过热，变形及爆管，高温段管板开裂、锅筒底部鼓包等。本文的论述在于：热水锅炉供暖系统中水渣的危害是相当严重的，作为供暖技术人员应转变传统的认识观念，并施之以科学的处理方法。对于供暖系统水渣的认识应从传统的一般认识范围升华而加以重新认识。因此目前在传统的认识基础上所采用的水渣处理方法是难以良好地解决存在的问题的。

Abstract: at present our country heating industry widespread use of the large capacity of central heating boiler system. The practice shows that the hot water boiler, the nets and the building of a closed loop system there is a lot of water residue, its effects are quite serious influence on the safety and reliability of the heating of the operation. Regardless of whether conduit boiler or fireworks tube boiler, often cause water wall tube clogged overheating, deformation and pipe explosion, high temperature period of tube plate cracking, pot tube bottom bulge, etc. This paper discusses the is that hot water boiler water heating system in the residue of harm is quite serious, as heating technology personnel should change the traditional ideas, and applied with scientific processing method. For water heating system in the residue of know general understanding range from traditional sublimation and to recognize them. So at present in the traditional know basis the water processing method is good slag is difficult to solve the existing problem.

在这里首先应当说明的是，我们提出的所谓的水渣与水垢有着一定的区别。蒸汽锅炉中进入锅炉的水是在锅炉内部不断的循环过程中被蒸发而变为蒸汽的，在这一循环过程中水中的致垢物质一盐份不断被浓缩着、被析出，而沉淀、附着在高温金属表面而形成白色的坚硬的水垢。而在热水锅炉中白色的水垢不常多见，而是常见含有多种成份的颜色为又黑而红的大量的松散状沉淀物质，因此称其为水渣是合适的，区别于水垢。应当承认在热水锅炉中也存在着水垢，经常可以看到爆管事故的管子内附着有白色的坚硬水垢。……
