在工場使用蒸汽系統中冷凝水是必然產生的物質，因為利用蒸汽加熱過程當中，經過熱移轉、蒸汽轉化成冷凝水滴，而這冷凝水滴必須快速在管路中排出以免影響蒸汽加熱的效益，也只為這理由蒸汽疏水閥自然成了蒸汽系統中的主件之一，若我們忽略了快速排出冷凝水會導致無法昇溫讓蒸汽加熱系統失效。
為節約能源及提高熱能利用率一般我們都會考慮另外安裝冷凝水回收管路至蒸汽鍋爐。而這回收管路我們建議安裝於設備頂部空間作稍有斜度管路順流快速回至蓄水槽式集氣桶再經由幫浦，打入鍋爐提高熱能。如圖 Figo 如果回收管路走地面 1 因地板的不平而影響水流須等整支管至注滿水時才能流回蓄水槽或集氣桶其間熱能將會無法達到熱能快速回收的目地 2 由於回收管路走地面妨礙作業人員及保養人員的通路降低工作效率影響整廠美觀。
During the operations of a steam system in a Plant condensate is generated without any exception. During heating with steam, the transfering of heat makes steam condense into condensate rops, and the condensate shall be discharged from the system through the piping for preventing from the steam heating efficiency. As a matter of the fact, this is why a Steam Trap is one of the essential units steam system. Once we from to take good care of discharging condensate rapidly from the system, the failure of being unable to bring up the temperature will ruin the steam heating system.
For energy saving and higher effective heat utilization rate, it is generally considered to equip the system, with condensate recollection pipe link to the steam boilr. It is recommended to install the pipes in the top room in a slightly inclined direction to speed up the flow of the condensate into the Water Reservoir type steam collection bucket, then, through the help of the pump, the condensate is enforced into the Steam Boiler and enhances the thermo-energy there (as shown in Fig.).
In case of the recollecltion pipe system is installed along the floor surface, the following disadvantaes will be found：
| 1. |
The pipes climbing up and down 3ong the floor surface can cause condensate water to be stopped in the pipe section at lower level until the whole pipe system is filled up with condensate, then, it can be sent to Water Reservoir or Steam collection bucket. Therefore, the heat is heat lowered, and purpose of heat-recovery is not achieved. |

| 2. |
The recollection pipe system can interfer the workers and maintenance personnel from walking smoothly and lower work efficiency. Besides, it affects the out-look of the factory. |
