Introduction to Vacuum Hot Water Boiler
A vacuum hot water boiler is a type of boiler that operates under negative pressure (vacuum state). The main principle is that the heat generated by fuel combustion is transferred to the heat medium water in the vacuum chamber of the boiler. The heat medium water boils and vaporizes at a relatively low temperature due to the low – pressure environment, and then the steam transfers heat to the heat exchanger, providing hot water for heating, bathing, and other purposes. Vacuum hot water boilers have many advantages, such as high safety (no explosion risk), high thermal efficiency, long service life, and environmental – friendliness, which make them widely used in various fields like hotels, hospitals, schools, and commercial buildings.
