1前言工业锅炉炉型和结构品种繁多,归纳起来,大致可分为烟管式和水管式两大类。其水循环方式大部分为自然循环,但也出现了直流水管用于工业锅炉。直流锅炉(强制循环)在大型电站中的超临界锅炉用得很多。但它用在中低压工业锅炉上,以前颇有争议,也是很值得探讨的问题。笔者对克雷登蒸汽发生器——直流水管锅炉作了一番探索,认为它有许多独到之处:安全、节能、金属耗量低、体积小。这是其它炉型很难比拟的,尤其是卧式锅壳锅炉。克雷登蒸汽发生器(以下简称蒸汽发生器)是一种直流水管锅炉,跟一般工业锅炉功能一样,可提
1 Introduction Industrial boiler furnace type and structure of a wide variety, summed up, can be roughly divided into smoke pipe and water pipe two categories. Most of its water circulation is a natural circulation, but also appeared in the water pipes for industrial boilers. DC boilers (forced circulation) are used in supercritical boilers in large power plants. However, it is used in medium and low pressure industrial boilers, which were quite controversial and worthy of discussion. The author made some exploration on Creden steam generator - DC water tube boiler and thought it has many unique features: safety, energy saving, low metal consumption and small volume. This is difficult to compare with other models, especially horizontal boiler shell. Credeon steam generator (hereinafter referred to as steam generator) is a direct current water tube boiler, with the function of general industrial boilers, can be mentioned
