From the names of atmospheric hot water boilers and non-pressure hot water boilers, we can distinguish that the former does not carry pressure and the latter carries pressure. This is a simple and intuitive difference. But in fact, there are many differences between the two types of boilers, and the applicable industry fields and operating locations are also different. Everyone should choose the appropriate boiler model according to their own needs for the hot water boiler, so that the boiler can work better for us. Xie Gong from Zhengzhou Fangkuai Boiler Factory introduced these two types of boilers to help everyone understand them more comprehensively.
In my country, atmospheric hot water boiler is also called pressureless hot water boiler, which means that the top of the boiler usually does not bear the static pressure of the water column of the heating system, which is equivalent to an "open hot water tank".
The meaning of atmospheric hot water boiler is that the opening of the boiler body communicates with the atmosphere. Under any working conditions, the boiler whose gauge pressure is zero at the boiler water level line; the boiler product model of atmospheric boiler is composed of three parts, and each part is connected by a short horizontal line.
Pressurized hot water boilers are the closed boilers we usually see. The steam and water system in the boiler is composed of closed containers and pipes, heated by flames, and subjected to fluid pressure during work, and belongs to special equipment.
The standard steam of the boiler refers to controlling the pressure and flow rate of the boiler in strict accordance with the process indicators. Steam includes saturated steam and superheated steam, which are divided into low pressure, medium pressure and high pressure steam.
