Abstract

本实用新型公开了一种燃油气锅壳式过热蒸汽锅炉,回燃室内设置有由若干分组换热管组构成的过热器,过热器的换热管接头在观察孔中汇集,过热器的进出口分别与蒸汽进出集箱接通。由于将过热器布置在回燃室内,使回燃室内烟气温度远大于前烟箱,在不改变原锅壳式锅炉结构的情况下,过热器换热效果大大提高,蒸汽品质也得到了保证,也容易维修。

Description

燃油气锅壳式过热蒸汽锅炉
技术领域
本实用新型属于锅炉领域,具体是涉及一种用于燃油气而产生热能的锅壳式过热蒸汽锅炉。
背景技术
现有技术的锅壳式过热蒸汽锅炉,其过热器一般安装在前烟箱中,或是将前烟箱做成膜式壁转烟室的干背结构。但是干背式结构的锅炉,由于烟气进入烟管时,只有烟箱进行密封,并没有受热面进行冷却,因温度高(1000℃左右),因此,制造工艺复杂,可靠性差,散热损失大。
实用新型内容
为了解决现有技术存在的问题,本实用新型提供一种换热效率高的锅壳式过热蒸汽锅炉。
为了实现以上目的,本实用新型的技术方案如下:一种燃油气锅壳式过热蒸汽锅炉,包括回燃室,所述回燃室内设置有由若干分组换热管组构成的过热器,过热器的换热管接头在观察孔中汇集,过热器的进出口分别与蒸汽进出集箱接通。
与现有技术相比,本实用型由于将过热器布置在回燃室内,使回燃室内烟气温度远大于前烟箱,在不改变原锅壳式锅炉结构的情况下,过热器换热效果大大提高,蒸汽品质也得到了保证,也容易维修。
附图说明
图1为本实用新型蒸汽锅炉的结构示意图。
图2为过热器布置示意图。
具体实施方式
如图1所示,回燃室2的内部设置有过热器1,蒸汽锅炉的外部设置有蒸汽进集箱5和蒸汽出集箱4。过热器由若干组换热钢管布置组成,换热钢管大部分弯曲,作为受热面起到传热作用。如图2所示,换热钢管的接头经过弯曲后全部通过观察孔3,并在锅炉的尾部汇集。汇总后分别与蒸汽进、出集箱接通。
