Description

一种立式水火管锅炉
本实用新型属于一种低压小容量立式水火管锅炉。
目前,公知的小容量锅炉在结构上及在运行中都存在不足之处:水管锅炉结构较复杂,要求运行技水水平较高,锅炉给水水质要求较高;烟管锅炉或烟火管组合锅炉的烟、火管由于是水平放置而易于积灰,造成传热情况恶化,锅炉出力降低。因此给用户使用带来不便。
本实用新型为克服上述不足之处,设计了一种低压小容量立式水火管锅炉,它具有结构简单、运行技术水平要求不高、锅炉给水不必进行严格处理和安全可靠等优点,方便用户使用及维护。
本实用新型是这样实现的:在锅筒内部和外部的环形烟道内分别设置有竖弯横斜火管及竖弯水管,以增加锅炉的辐射面和对流受热面。火管的竖管段端焊接于凹型锅底,并与炉膛相通。横管段端焊接于锅筒外壳上,管段有向下倾斜,并与环形烟道相通。在环形烟道内设置的竖弯水管,其上端焊接于锅炉运行时最低水位处,下端焊接于锅筒下部,使锅筒的水和水管里的水相互流通。
由于采用了上述方案,在炉膛内未设置有水管,减少了因水管在高温状态下工作而使管内壁易结构的缺点。燃料在炉膛内燃烧后,烟火将通过锅筒内的竖弯火管经锅筒外壳的环形烟道进入烟囱排向大气。火管是竖直在炉膛上方,火焰直接进入管内,将高效地辐射热能。横弯管段因是向下倾斜而大大减少了积灰,大大改善了传热环境,提高了锅炉效率。
下面结合附图和实施例对本实用新型进一步说明。
图1为锅炉构造图,图2为A-A向剖视图。
参照附图,锅炉由炉体〔1〕和锅筒〔5〕构成,两者可分离,锅筒是放置在炉体上,炉体的上部与凹形锅底构成炉膛〔3〕。炉体内的下部为灰室,炉膛与灰室间由炉篦〔2〕隔开。在锅筒内部设置有竖弯横斜火管〔6〕,火管的竖管段端焊接于凹形锅底,并与炉膛〔3〕相通,横管段向下倾斜,管端焊接于锅筒上,并与环形烟道〔7〕相通。在锅筒外壳上的环形烟道内设置有竖弯水管〔15〕,水管上端焊接于锅筒最低水位处,下端焊接于锅筒下部,在锅筒底部设有排污阀〔4〕、上部设置有安全阀〔9〕、压力监测装置〔10〕、输汽阀〔11〕、检查孔〔12〕、进水阀〔13〕和水面指示器〔14〕等。
