双层燃烧锅炉也叫逆向燃烧锅炉或反烧锅炉,是近年来再次发展起来的一种炉型.由于它具有热效率高、消烟除尘好、造价低、操作简单、维修方便等特点,得到了广泛应用。但由于这种炉型在运行管理方面存在问题,故障率较高。一、双层燃烧锅炉常见故障 1.水冷炉排管的变形爆管事故由于水冷炉排管热负荷强度较高,水平倾角较小,水循环较弱。因此,对于蒸汽锅炉,
Double-layer combustion boiler, also called reverse combustion boiler or anti-burning boiler, is a kind of furnace that has been developed again in recent years.It has the characteristics of high thermal efficiency, good smoke and dust removal, low cost, simple operation, easy maintenance and so on widely used. However, due to the operation and management of this furnace there are problems, the failure rate is higher. First, the double-fired boiler boiler failure 1. Deformation of water-cooled grate tube burst tube accident As the water-cooled grate heat load higher intensity, smaller horizontal angle, the water cycle is weak. Therefore, for steam boilers,
