Steam heating is mainly the use of vaporization heat released when steam is condensed. With steam as the heat medium, the temperature of the surface of the radiator can be increased, and the heat transfer coefficient is also increased accordingly. Therefore, the number of fins of the steam heating system can be reduced by 30%-40% compared with the number of finned tube radiators of the warm water heating system. .

Therefore, the number of fins of the steam heating system can be reduced by 30%-40% compared with the number of finned tube radiators of the warm water heating system. . The steam can be used at a higher flow rate, so the pipe diameter is smaller than that of the warm water heating system, thereby reducing the construction cost.
The thermal inertia of the steam heating system is smaller than that of the warm water heating system. That is to say, the steam heating system can dissipate heat quickly after steaming, and can cool down quickly after stopping steam. This feature is suitable for factory workshops that require timed heating, theaters. And other places. In addition, due to the small bulk density of steam, even in high-rise buildings, there is no excessive pressure on the bottom radiator. When the warm water heating system is used in high-rise buildings, measures must be taken to limit the static pressure of water.
The disadvantage of steam heating is that the surface temperature of the finned tube radiator is too high, which causes the decomposition of organic matter dust, which makes people feel hot and smelly, especially when using high pressure steam. The surface temperature of the radiator and the open tube of the high-pressure steam system are both above 100 degrees Celsius, which is likely to cause burns to the human body. If the condensate in the steam pipe cannot be discharged smoothly, it will also produce water hammer, vibration and noise, which will affect the environment.
