Description
新型高效节能燃油燃气热水锅炉
技术领域：
本实用新型属于锅炉产品，尤其是涉及一种燃油燃气热水锅炉。背景技术：
随着人们对环保和节能意识的增强，现代燃油燃气锅炉也向着组装化、自动化方面发展，和早期的卧式锅壳式燃油燃气锅炉相比，现代卧式锅壳式燃油燃气锅炉主要在结构上进行了改进。 一是干背式锅炉结构，其制造工艺简单，制造工时少，因此采用这一结构的厂家很多，但经过多年的运行暴露出来的问题很多，炉胆出口的高温烟气直接和后烟箱盖冲刷，后烟箱多为耐火砖制成，容易损坏，不得不经常停炉修理，縮短了锅炉的正常运行周期。二是全湿背式中心回燃结构，这种结构炉胆出口烟温相对较高，因此对前烟室的要求较高，国外此类锅炉前烟室的耐火层都是异性浇注，密封和固定都比较好，但这种结构对流受热面必须采用螺纹管，设计时对螺纹管的加工精度要求比较严格，否则锅炉的排烟温度会出现较大的波动。三是全湿背式下置式炉胆结构，该结构采用大直径炉胆，增加了炉膛辐射换热，降低了进入回转室前管板的烟温，改善了回燃室前管板的工作状态，但烟管的布置一般采用"△"布置方式，烟管一般呈阶梯状，放置在炉胆左、右侧上方，为保证标准要求布置，导致锅炉锅壳和管板直径过大，造成不必要的浪费。发明内容：
本实用新型的目的是：针对上述存在的技术问题和缺陷，提供一种结构紧凑合理、运行安全可靠、燃烧效率高、造价低、使用寿命长的新型高效节能燃油燃气热水锅炉。
本实用新型的技术方案是：由锅炉本体、燃烧器、保温层、烟筒、电控柜、底座、管道阀门仪表组成，锅炉本体采用波形炉胆、螺纹烟管和光管，波形炉胆中心布置，螺纹烟管和光管布置在波形炉胆的周围，波形炉胆的尾部为湿背式回燃室，螺纹烟管与湿背式回燃室和前烟箱相连通，组成第二回程对流受热面，光管与前烟箱和后烟箱相连通，组成第三对流受热面。
本实用新型的有益效果是：由于采用三回程湿背式结构，燃烧充分、无污染，低噪音；波形炉胆居中布置，使热胀冷縮的应力得到均匀缓冲，使设备寿命延长；受热面围绕炉胆均匀布置，供热面积大，排烟及散热损失小，热效率高，可达90%以上；具有结构紧凑，运行安全可靠，占地面积小，节省材料，造价低，启动快等优点。附图说明：
图1为本实用新型的结构示意图；
图2为图1的左视图。
图中标注说明：
1、前烟箱，2、锅炉本体，3、管道阀门仪表，4、光管，5、螺纹烟管，6、保温层，7、检修门，8、烟筒，9、防爆门，10、观火口， 11、后烟箱，12、底座，13、波形炉胆，14、燃烧器，15、电控柜。具体实施方式：
从图1所示本实用新型的结构示意图和图2的左视图可以看出，本实用新型由锅炉本体2、燃烧器14、保温层6、烟筒8、电控柜15、底座12、管道阀门仪表3组成，锅炉本体2包括锅壳、波形炉胆13、螺纹烟管5和光管4。本实用新型采用湿背式三回程全对焊结构，波形炉胆13中心布置，即全中心对称结构，展开式火焰、阔容辐射式受热面。受热面采用全波纹炉胆、螺纹烟管5与光管4优化组合设计结构，使火焰产生强烈扰动，大大提高传热系数，降低排烟温度。螺纹烟管5和光管4布置在波形炉胆13的周围，波形炉胆13的尾部为湿背式回燃室，螺纹烟管5与湿背式回燃室和前烟箱l相连通，组成第二回程对流受热面，光管4与前烟箱1和后烟箱ll相连通，组成第三对流受热面。燃料先在由波形炉胆13组成的炉膛内燃烧，生成的烟气再由湿背式回燃室内转弯，进入由螺纹烟管5组成的第二回程对流受热面，然后经前烟箱1进入由光管4组成的第三对流受热面，最后经烟筒8排入大气。
本实用新型采用三回程湿背式结构，采用高效传热元件螺纹烟管和原装进口燃烧机，燃烧充分、无污染，低噪音。前烟箱1和后烟箱11之间有铰链连接，且后烟箱ll内设有检修门7，炉体内开设人孔、手孔，简化了清洁工作，使维修、养护极为方便，便于炉膛检修和清扫，锅炉尾部设有观火口IO，可以观测炉膛的燃烧情况。自控系统采用全自动操作，从锅炉的点火至负荷调节，锅炉熄火等均实现自动控制和调节，可实现全自动操作。锅炉保护系统齐全，有熄火保护、超温保护、超压保护等系统，运行安全可靠。在燃烧器14内装有高电压自动点火系统，点火可靠。燃烧器
14的调风系统随喷嘴的喷油量自动跟踪调节，燃烧器的燃烧效率高。保温层6采用轻质硅酸铝纤维保温，减少了散热损失，外用全不锈钢板蒙皮，提高了外观质量。
在正常情况下，燃烧器出力随锅炉压力而自动调整燃烧，出水温度达到设定值时，燃烧器自动停机，当温度低于设定值时，燃烧器自动开机。当发生缺相、超高温、超压、燃烧器的进风口吸入异物等现象时，燃烧器会自动停机，故障灯亮，程控装置会立刻停止输出燃料，消除故障后才能重新起炉。每次点火前均自动进行一分钟强风吹扫，排出炉内余留的可燃气体，防止点火时的爆燃现象发生，同时在锅炉后烟箱ll内设置内置式防爆门9，当炉膛发生爆燃时，防爆门盖自动开启，可燃气体进入后烟箱ll，通过烟筒8排向大气（而不是排到锅炉房内，避免发生火灾事故），泄放压力后，防爆门盖自动关闭，确保了锅炉的安全运行。
