What is a vacuum hot water boiler
There are many types of hot water boilers, one of which is a vacuum hot water boiler. It is a boiler equipment that heats cold water through phase change heat exchange in a vacuum state. It consists of a combustion chamber, water pipes, negative pressure steam chamber, heat exchanger, heat medium water, etc. When working in a vacuum state, it causes the heat medium water to boil, evaporate, condense, and circulate in a closed body, thereby heating the water in the heat exchanger. A vacuum hot water boiler needs to be set to a vacuum degree, generally within the pressure range of 2.67KPa-66.6KPa.
A vacuum hot water boiler, also known as a vacuum phase change hot water boiler, refers to a boiler that heats cold water through phase change heat exchange when the internal medium pressure of the boiler is lower than atmospheric pressure during normal operation. The boiler body is vacuum sealed, and the heat medium water is burned under negative pressure. The steam produced exchanges with the heat exchanger, resulting in high thermal efficiency, safety, and stability.
