2、的基础上自行研制开发的一种高效节能燃 油供热设备，供热能力为1X4.18X106kJ/h30X4.18X 106kJ/h。热风炉主要由燃料供应 装置、供风装置、燃烧装置、燃烧室、混合室及热工控制系统组成。本产品结构简单、体积小巧、操作安全、维护简便、使用寿命长、供热范围广，温 度可随意调配，广泛应用于水泥、化工、冶金等行业中的烘干、焙烧设备提供热源。二、工作原理燃油热风炉工作原理：燃料由供应装置安全输送到燃烧器， 与供风装置送入的空气 经燃烧器组织在燃烧室里充分燃烧，产生的高温气体在混合室内与冷空气混合得到符合 工艺要求的热烟气。三、规格与技术参数产品型号n=130，n=1 表示 1X 4.1

3、8X 106kJ/h 供热能力G表示高温型，供热温度为 6001200CZ表示中温型，供热温度为300600CD表示低温型，供热温度为100300C燃油热风炉 四、安装调试与操作使用规程 安装炉体安装：炉子要安装在牢固的基础上，各连接法兰之间应加石棉绳密封，详见燃油热风炉安装 图。燃烧机安装:1、燃烧机的喷火口应插入炉膛火口之内，其深度视炉墙厚度而定，不宜大于150毫米 炉墙火口内径比燃烧机前端外筒大于 15毫米，火口呈4550锥角，这样可避免烧 重油时，在火口锥面上结焦。2、插入深度及倾斜角度等定妥后， 把燃烧机外面的活动法兰焊在外筒上。 如炉膛有 正压，则在法兰与炉墙板之间加垫石棉板，以免

4、炉内火焰外冒。这样可防止烧毁机壳， 且节约能源， 炉内正压如大于 10毫米水柱以上，用户应在炉尾加引风机抽炉尾气排出、 或加高抽风烟囱。3、燃烧机用 36 个压板螺钉将焊连在燃烧机前端外筒上的法兰或用压板固定在炉 墙板面上 ,或用支撑架固定即可。4、 打开风机电机上的电线盖板，接通输入电源，检查电机方向是否正确。5、安装输油泵时，应检查电机方向是否与铭牌方向一致。油管路上应有过滤装置， 还应有回油系统，靠燃烧机前应有油管接头及压力表，表之外应安装有可调节针型阀， 再用软管连接。6、烧重油用户， 输入油路应有蒸汽保温与蒸汽扫管线的装置。 点火前应有蒸汽扫线 与预热油路、喷油嘴等。重油到炉前的油温

5、不低于120C130C,否则雾化不好，在火 焰筒内易产生结焦。操作使用1首次点火前的检查工作：检查燃烧机及其配套件安装情况，检查油路、电路、风路是否安全畅通。接通电源， 手动检查风机及油泵运转方向是否正确。 若是反转了、 则应断开电源开 关，将反转的油泵、风机接线任意换 1 相即可改变转动方向。检查油路、风路电磁阀和 调节阀是否动作，再将输油软管从喷油嘴上扭下，打开油阀，放油一刻钟到桶中，目的 是清除输油管路中的杂质。观察后如无异常情况，可进入手动点火调试工作，手动点火 调试工作正常后，方可进行自动或中控操作。每次点火前的准备工作： 清除炉膛中的积渣、杂物，打开风机吹扫炉膛 35分钟。 若燃用

6、重油， 应先打开加热重油的蒸气阀门约三分钟， 待管中积水放完， 开始冒 汽时关阀， 再打开扫线汽阀及喷油嘴上手轮阀， 使蒸气沿未被保温的油路及喷油嘴喷入 燃烧机及炉膛中，将油路及油嘴等预热，约 10分钟待油嘴体表面烫手后，可关蒸气。2.调试 打开烟道龙门阀，关闭风机风门，启动风机，此时炉膛应有负压，打开风门吹扫炉 膛后再关闭风门。调整回油管道上的调节阀，启动油泵，使其油压上升到I.OMPa,点火后发现燃烧冒烟，可能是油压调得过高，手动将回油阀门调大，观察火焰状况，直到 不冒烟为止。 炉温或料温不够， 可能是供油压过低， 将回油调节阀慢慢关小， 油压升高， 火量增大，同时手动调整风门，直到燃烧稳

7、定达到所需要温度为止。如仍达不到温度要 求，则检查其它原因或检查是否属选型过小，应换大一型号燃烧机。3.正常安全操作规程 检查机、电设备是否正常，油、气管路是否通畅，清除喷嘴口的积油或焦块。 点火前要打开管道调节阀，启动鼓风机时，风阀要关严密，待正常运行后，打开 风阀吹扫炉膛 3-5分钟，然后关掉调风阀 点火时，要使炉内处于负压状态，压力保持在 -100-150Pa；如负压大影响点火 时，可调整管路阀门，同时保证炉膛处于微负压状态。 一般情况下，炉内温度控制在V 800E，根据需要通过管路调节阀及炉膛挡火板 微调烟气温度使之符合工艺要求（一般在100300C，依据对象不同而定）。 根据尾气温度

8、需要，调整油压，根据燃烧火焰状况调整风阀。在同一油压下，通过调节风阀 ,保证燃油充分燃烧 ,火焰不宜过长。如要加温，先加大油压，同时要加大风 门。减压就相应减风。 如系冷炉，则不能升温过快，开小火逐步升温 10分钟左右再开大火。 停炉时，先关烧嘴进油电磁闸阀，再关油泵。3分钟后停止供风风机，关闭管道调节阀。 自动操作时， 系统启动后按照程序自动运行， 根据尾气温度变化对调节阀进行自 动调节使系统达到供热平衡。3.注意事项： 如点火未着，则迅速关闭油阀，开大风量吹扫炉膛，3分钟后再按程序点火，以防炉膛内油雾积累过多汽化再次点火时引起爆炸。 点火时，操作人员必须站在点火孔侧边，注意回火引起事故。

9、如出现火焰易脱火，燃烧不稳的情况，应调小风阀，将火焰烧到燃烧器里面，再 适当调大即可。 如出现燃烧火焰过短， 或火焰明显变形， 就可能是油枪出现堵塞而异致雾化不良 燃烧不好， 处理方法是将油枪前端油咀部分折开清洗雾化片和旋流套， 然后按顺序装配 即可（注意要拧紧） 。 油泵的使用压力在 0.51.5MPa之间，可根据炉温所需而调整，但不允许将炉膛 烧红导致炉体变形。五、维护保养与常见故障的排除维护保养 过滤网应及时拆洗，清除杂质、修补滤网损处。 火焰筒应定期清扫，保持筒壁面的干净与气道的畅通。特别当油质差、油温低， 空气不干净时更应勤于清扫。 油枪应定时拆洗，保持流道的畅通。拆卸油枪应按程序与

10、规定进行，不能损坏。 经常检查油温、油压、风压仪表的准确性。 经常检查各种阀门的密封性。 火口砖锥面上不能有杂物堆积，应及时清扫，否则会引起回火，烧坏燃烧器。 经常检查风路、油路的密封性。 工作时应保持蒸汽能在重油油路的保温套管中流动 喷油嘴中雾化片零件如发现有磨损，应及时更换，否则影响雾化效果。 火焰筒如有损坏应及时修复，否则因损坏而改变空气流通面积，影响燃烧效果常见故障的排除 （见表 ）- 5 -障 一鄭因法 方 除-点火不着化I 不杳一器 检压正常燃烧冒烟正常燃烧时熄火枪 袖火焰筒内结焦严重筒1.或 大 孔 片 化1小3,过燃烧机火口涌油2.火口內结焦或回火強同命4六、安全事项1、点火时

11、，工作人员不得站在炉前，以免爆燃喷火伤人。2、火焰熄灭或一次点火不成功，应立即停止点火，关闭供油阀和空气阀，排除炉 内未燃烬的油气后再重新点火；燃用重油时，还需接通蒸汽清扫供油管路，排除未燃烬 的油气后再重新点火。-7 -.
