Description

一种新型汽化油枪
                        技术领域
本实用新型属于一种燃油装置，具体地属于电站煤粉锅炉点火助燃用的油枪。
                        背景技术
目前电站主要以煤粉作为燃料，煤粉无法直接点火燃烧，需使用油枪来进行点火，由于我国有些地区的煤层较差，挥发成份少，因此需设有油枪作为助燃火源，才能稳定燃烧，普通火力发电厂燃油油枪由于燃油温度低，普遍存在燃烧初期燃烧不完全、冒黑烟、火焰温度低的特点，其最大的缺点就是费油，而且燃烧情况也不理想。
                        发明内容
本实用新型所要解决的技术问题是：提供一种结构简单、提高燃烧效率的新型汽化油枪。该油枪采用蒸汽对燃油进行预热，从而提高燃烧效率和火焰温度。
为了解决上述技术问题，本实用新型采用以下的技术方案：一种新型汽化油枪，包括燃油导管，其特征在于：所述燃油导管外设有对燃油预热的蒸汽导管，蒸汽导管上设蒸汽入口和出口。
为了解决上述技术问题，本实用新型采用以下进一步的技术方案：所述的燃油导管盘成螺旋状。
所述蒸汽入口设在靠近油枪的出口处，蒸汽出口设在靠近油枪的入口处。
本实用新型与现有技术相比具有以下的优点：1、利用通入蒸汽导管中的蒸汽对燃油进行预热，并采用逆向流动加热，从而提高燃烧效率和火焰温度；2、结构简单，制造成本低，易于推广。
                       附图说明
图1为本实用新型的剖视图。
图2为本实用新型的俯向视图。
                     具体实施方式
参见各图，本实用新型是对现有技术的改进，其改进之处在于：油枪的燃油导管1外设有蒸汽导管2，蒸汽导管2的两端封闭并与燃油导管1连为一体，蒸汽导管2上设蒸汽入口3和出口4，利用高效蒸汽换热器将蒸汽从蒸汽入口3送入蒸汽导管2内，使燃油导管1内的燃油预热，高温燃油在导管内由于压力高，还处于液化状态，一旦喷出油枪即迅速蒸发汽化，从而提高燃烧效率和火焰温度。为了增强蒸汽对燃油的预热效果，燃油导管可盘成螺旋状，如图1所示，也可弯成其它现有技术中所描述的形状，这样可延长燃油在导管内停留的时间，使燃油充分预热，另外，蒸汽入口3设在靠近油枪的出口处，蒸汽出口4设在靠近油枪的入口处，蒸汽出口4在油枪下部，这样可充分利蒸汽，并采用逆向流动加热，将冷却后的蒸汽水从蒸汽出口4排出。
本油枪用于电站煤粉锅炉分级燃烧器的引燃能量来源，其结构简单，制造成本低，适合在电站锅炉中应用和推广。
上述实施例仅供说明本实用新型之用，而并非对本实用新型的限制，有关技术领域的普通技术人员，在不脱离实用新型的精神和范围的情况下，还可以做出各种变化和变型，因此所有等同的技术方案也属于本实用新型的范畴，本实用新型的专利保护范围应由各权利要求限定。
