蒸汽锅炉系统中的蒸汽，从锅炉出来到蒸汽使用点上，需要经过蒸汽分配系统进行蒸汽的分配。蒸汽分配系统是蒸汽锅炉系统中连接蒸汽源与蒸汽设备必需的部件。
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.
在蒸汽的分配过程中，需要让用汽设备得到高品质的蒸汽，除了蒸汽锅炉本身的蒸汽品质控制外，蒸汽分配系统也是关键。蒸汽锅炉所产生出来的蒸汽通过蒸汽管网输送到蒸汽的用汽设备上。一般来说，有一根或者多根的蒸汽管道向蒸汽点输送蒸汽，蒸汽管道在输送途中可能会产生分支，再通过分支管道输送到用汽点。
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.
在蒸汽锅炉启动并从管道输送到用汽点时，必须先在蒸汽分配系统中进行“暖管”，在启动阶段时，冷凝率一般比较大，会有一定的“冷凝负载”，会产生冷凝水。在运行过程中，由于蒸汽管道的散热，也会产生“运行负载”产生冷凝水。为了维持蒸汽供给，蒸汽锅炉必须产生更更多的蒸汽和进行补水，同时及时进行冷凝水的排放，以保证蒸汽的连续供应和蒸汽品质的保障。
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.
