Difference Between Vacuum Boiler and Atmospheric Pressure Boiler

Date:2019-10-18 share us:

Sitong Boiler has different kinds of hot water boiler, and mainly divided into vacuum water boiler and atmospheric pressure water boiler. The internal pressure of vacuum water boiler is negative, could realize the goal of fast hot water output and constant temperature, at the same time vacuum water boiler could transform into atmospheric pressure water boiler through change some related structure. The vacuum boiler is operate safely, as the working temperature is always lower than 90℃,and the pressure is lower than -30KPa, there will not lead to expansion and blast.

The water volume of vacuum water boiler is little, so the water need to be heated for several times by burner, while the water volume of atmospheric pressure water boiler is larger, so the water is heated faster than vacuum boiler, and the thermal efficiency of atmospheric pressure boiler is higher than the other one.

In order to be vacuum, vacuum water boiler has to be equipped with a series auxiliary equipment, such as vacuum pump, while the atmospheric pressure boiler do not require control equipment to keep vacuum, so the operation of atmospheric pressure is easier.
