The working pressure of the vacuum boiler is below 0.07MPa, so the boiling point of water is also reduced. According to the physical characteristics of water, at 1 standard atmosphere, the boiling point of water is 100 degrees Celsius. When the pressure is reduced to 0.07MPa, the boiling point of water is reduced to about 80 degrees Celsius. This is why pressure cookers are used to cook rice in plateau areas, that is, the boiling point of water at atmospheric pressure is too low to cook raw rice.

Water has a lower boiling point, so it needs less fuel. The thermal efficiency of our vacuum hot water boiler is as high as 94.6%, which is leading in the industry and has incomparable advantages. At the same time, using the wet-back FGR structure, the front and rear smoke boxes have maintenance positions, the overall operation of the boiler is more safe, operation and maintenance is more convenient.

The vacuum hot water boiler produced by our company has obvious advantages, and we look forward to cooperating with you!
