Description

Technical Field

[0001] The utility model relates to the technical field of steam air heaters, in particular to a steam air heater. Background Art

[0002] A steam heater is a device that uses steam to generate heat, and is mainly used to provide a warm environment indoors. Its working principle is: steam is generated by burning fuel (such as natural gas, oil or electricity), and the steam releases heat in the heating element, which is then transported to the fan through a pipe. The fan blows the heat in the steam into the room, thereby raising the indoor temperature.

[0003] Upon investigation, it was found that the Chinese utility model patent with publication number CN209926602U discloses a steam air heater for a power station boiler. The steam air heater has heat dissipating fins, and the spiral heat dissipating fins guide the air to flow around the steam pipe, which can extend the contact time between the air and the steam pipe, and help ensure that the air fully absorbs the heat in the steam; however, during the operation of the steam air heater, the steam can transfer heat to the air through the air duct and the steam pipe, and when used under low ambient temperature conditions, when the steam is initially passed into the steam pipe, due to the low temperatures of the steam pipe and the heat dissipating fins, condensation will occur on the inner wall of the steam pipe when the steam is passed in, but the condensed liquid cannot be recovered in the above-mentioned air heater, and the liquid in the steam pipe will have a certain impact on the heat conversion.

[0004] Therefore, the utility model provides a steam air heater to solve the above problems. Utility Model Content
