       本发明提到的一种提高注汽锅炉蒸汽干度的干度提升器的使用方法，其技术方案是：包括以下过程：
启动时，湿饱和水蒸汽自冷却介质入口（2.1）进入装置，然后控制压缩空气自压缩空气入口（1.1）进入装置，再控制燃料自燃料管（1.5）进入装置，同时按设置参数启动点火器点火，燃料在内混式燃料喷嘴（1.12）中被压缩空气雾化后喷入燃烧筒（2.5）的燃烧段（2.5.1），燃料空气混合物遇明火后即可着火燃烧。
       工作中，压缩空气经压缩空气入口（1.1）、压缩空气进气通道（1.3）、压缩空气流通孔（1.8），一路进入燃料管（1.5）与燃料管通道（1.4）形成的环形空间，并经环形空间进入内混式燃料喷嘴（1.12），对燃料进行充分雾化，同时压缩空气在流通的过程不但给前端头（1）进行良好的散热，自身温度的提高也更利于燃料的雾化；另一路进入压缩空气散热孔（1.10），通过压缩空气散热喷嘴（1.11）的圆周上均布的平行于前端面（1.9）的空气散热喷孔（1.14）高速喷出，在前端头的前端面表面形成一层空气冷却气膜，充分保护了前端头（1）的前端面（1.9）及点火杆端头、内混式燃料喷嘴（1.2）的端头在高温燃烧状态下不被烧蚀，其中，燃料管（1.5）与内混式燃料喷嘴（1.12）的一体结构，在出现内混式燃料喷嘴（1.12）损坏时，便于拆卸更换。
       工作中，湿饱和水蒸汽沿相反切线方向进入环形冷却介质通道（2.3），形成较强的旋转力，在旋转力的作用下，两相流的湿饱和水蒸汽在环形冷却介质通道（2.3）内得到充分混合，通过冷却介质流通孔（2.4），均匀的进入燃烧筒（2.5）外壁的多级螺旋式冷却介质通道（2.5.4），多级螺旋式冷却介质通道（2.54）散热面积大，湿饱和水蒸汽在燃烧段（2,5.1）外壁的流通时间长，流动均匀，有效地保护了燃烧筒（2.5）不被高温烧蚀；湿饱和水蒸汽在经过燃烧筒喉管段（2.5.2）外壁的环锥形冷却介质通道（2.5.5）时，流速大幅增加，保证了喉管段（2.5.2）内部不被高温烟气烧蚀；湿饱和水蒸汽沿环锥形冷却介质通道（2.5.5）末端的冷却介质喷孔（2.5.6）高速喷入燃烧筒（2.5）的混合段（2.5.3），与燃烧后的高温烟气迅速进行热量交换，混合形成复合气体，湿饱和水蒸汽干度得到大幅提升，根据工艺要求，干度可控制提升至100%，甚至达到一定的过热度，复合气体通过燃烧筒（2.5）的混合段（2.5.3）的尾端上的复合气喷孔（2.5.7）喷出，混合段（2.5.3）尾端的锥形及喷孔结构，可使湿饱和水蒸汽与高温烟气在经喷孔喷出时得到充分均匀混合；燃烧筒（2.5）喉管段（2.5.2）的设计结构，使燃烧后的烟气在经过喉管段（2.5.2）后，流速可接近音速，不但消除了燃烧段（2.5.1）内的火焰振荡现象，保证了高压燃烧的稳定，同时避免了混合段（2.5.3）内的湿饱和水蒸汽回流到燃烧筒（2.5）的燃烧段（2.5.1）内，干扰火焰的稳定。
有益效果
本发明与现有技术相比，具有以下优点：

2.本发明的内混式燃料喷嘴，有效地保证了燃料在高压条件下得到良好的雾化效果，同时避免了火焰回火问题，并且燃料管与内混式燃料喷嘴的一体结构，即使出现喷嘴损坏，极易拆卸更换，大大节约了运行成本；
3. 本发明的冷却介质通道及流通结构，不但适用采用常温软化水作为冷却介质的高压燃烧装置，特别适用于以高温湿饱和水蒸汽作为冷却介质的高压燃烧装置，湿饱和水蒸汽沿相反切线方向进入冷却介质通道（环形通道），在旋转力的作用下，两相流状态的湿饱和水蒸汽得到均匀混合，更利于湿饱和水蒸汽对燃烧筒外壁的降温；
4. 本发明的燃烧筒燃烧段外壁的多级螺旋式冷却介质通道，散热面积大，冷却介质在燃烧段外壁的流通时间长，流动均匀，有效地保护了燃烧筒不被高温烧蚀；燃烧筒喉管段的特殊结构可使燃烧后的烟气流速接近音速，消除了燃烧段内的火焰振荡现象，保证了高压燃烧的稳定，同时避免了因冷却介质的回流干扰火焰的稳定；
