燃烧室
摘要：
一种流化床炉燃烧室,所述流化床炉具有一个作为燃烧室下封闭端的喷嘴底和水平限定燃烧室边界的炉壁,所述炉壁包括:一个基本上垂直的且位于燃烧室上部内的上管壁段,其中管如此与翼片或接片相连,即它们构成了管壁;一个在燃烧室下部内的耐火的加衬下管壁段;一个在上管壁段和耐火的加衬下管壁段之间的管壁中间段,其特征在于,－至少在管壁中间段内的管壁的水平段的管涂有一个布置在燃烧室侧壁上的保护层,－所述在管壁中间段内的管壁的水平段的管具有一个相对上管壁段的管外径如此缩小的外径,即保护层的外轮廓在垂直方向上不相对上管壁段的管壁外轮廓突出。
摘要（英）：

The present invention discloses a combustion chamber of the fluidized-bed furnace, which has a nozzle bottom as the lower enclosed end of combustion chamber and a furnace wall for limiting the horizontal boundry of combustion chamber. Said furnace wall consists of an upper pipe-wall segment vertical basically and inside the upper part of combustion chamber, a refractory and lined lowern pipe-wall segment inside the lower part of combustion chamber,and a middle pipe-wall segment between said both, which features that its horizontal pipes are coated by a protecting layer and have smaller external diameter to prevent its protecting layer from being convex.
