蒸汽鍋爐系統中的蒸汽，從鍋爐出來到蒸汽使用點上，需要經過蒸汽分配系統進行蒸汽的分配。蒸汽分配系統是蒸汽鍋爐系統中連接蒸汽源與蒸汽設備必需的部件。
Steam in the steam boiler system, the steam from the boiler to the out point of use, needs to be distributed through the steam distribution system of the steam. Steam distribution system is a source of steam and steam equipment components necessary to connect the steam boiler system.
在蒸汽的分配過程中，需要讓用汽設備得到高品質的蒸汽，除了蒸汽鍋爐本身的蒸汽品質控制外，蒸汽分配系統也是關鍵。蒸汽鍋爐所產生出來的蒸汽通過蒸汽管網輸送到蒸汽的用汽設備上。一般來說，有一根或者多根的蒸汽管道向蒸汽點輸送蒸汽，蒸汽管道在輸送途中可能會產生分支，再通過分支管道輸送到用汽點。
In the allocation process steam, the need to obtain a high quality steam steam equipment, in addition to its own steam boiler steam quality control, steam distribution system is also key. Arising out of steam boiler steam to the steam delivery device with steam through the steam pipe network. Generally, there are a plurality of steam or a steam pipe to the steam delivery point, steam pipes may be generated in the conveying branch of the way, and then transported to the point of steam through the branch pipe.
在蒸汽鍋爐啟動并從管道輸送到用汽點時，必須先在蒸汽分配系統中進行“暖管”，在啟動階段時，冷凝率一般比較大，會有一定的“冷凝負載”，會產生冷凝水。在運行過程中，由于蒸汽管道的散熱，也會產生“運行負載”產生冷凝水。為了維持蒸汽供給，蒸汽鍋爐必須產生更更多的蒸汽和進行補水，同時及時進行冷凝水的排放，以保證蒸汽的連續供應和蒸汽品質的保障。
In the steam boiler is up and transported from the pipe to the point when the steam must be "warm tube" in the steam distribution system, in the start-up phase, the condensation rate is generally relatively large, there is a certain "condensing load", will produce condensation water. During the operation, due to the heat of steam pipes, will have a "run load" condensation. In order to maintain the steam supply, steam boilers must produce more and make more water vapor, and timely discharge of condensate, in order to ensure a continuous supply of quality guarantee and steam vapor.
