What is the optimal vacuum level for a vacuum hot water boiler
A vacuum hot water boiler has the concept of vacuum degree, which refers to the degree of rarefaction of gas in a vacuum state. Its value represents the actual value of system pressure that is lower than atmospheric pressure, that is, vacuum degree=atmospheric pressure – absolute pressure.
The boiling temperature of water will vary under different pressures. In a vacuum state, the heat medium water is easily boiled and vaporized, so the vacuum degree of the vacuum hot water boiler should be set appropriately. Generally speaking, the vacuum degree of a vacuum hot water boiler is set within the range of 2.67KPa-66.6KPa, corresponding to a saturation temperature of 15-85 ℃.
