Vacuum boilers are characterized by their safety, high efficiency, and low maintenance requirements. These features make them ideal for scenarios where stable, efficient, and safe hot water and steam supply is essential. They are widely used in various applications, including residential and commercial heating systems, hotels, hospitals, and industrial processes, where reliability and energy efficiency are critical factors.

What is a vacuum boiler?Why choose our company's vacuum boiler？

A vacuum boiler is a type of hot water boiler. It is mainly composed of a combustion chamber, a heat exchanger, a vacuum chamber and other parts. The inside of its furnace is a closed vacuum environment, which is filled with an appropriate amount of heat medium water. The design pressure of our company's vacuum boiler is lower than atmospheric pressure, between - 0.02MPa and - 0.08MPa, which is a significant difference from traditional normal pressure or pressure boilers. In some industrial production processes with high requirements for temperature control, such as food processing, pharmaceuticals, chemicals and other industries, vacuum boilers can provide stable hot water or low-pressure steam.

1.Our equipment has higher thermal efficiency

The vacuum boiler adopts the vacuum phase change principle, and the heat exchange efficiency between heat medium water and circulating water is high. The combustion chamber of the boiler designed by our company can make the fuel fully burn and reduce heat loss. At the same time, since there is no large amount of steam-water co-evaporation, the heat carried by the steam can be effectively transferred to the circulating water, so that the overall thermal efficiency of the boiler can reach more than 90%.

2. Our equipment lasts longer

The internal vacuum environment reduces the corrosion of metal parts by oxygen. Under normal maintenance, the service life of the vacuum boiler can reach more than 20 years.

3. Our equipment is more environmentally friendly

One of the vacuum boilers includes a flue gas heat recovery device with a compact structure, which can absorb heat from high-temperature flue gas and low-temperature return water, thereby improving heat transfer efficiency and saving gas costs. This boiler is equipped with an ultra-low nitrogen burner to reduce nitrogen oxide emissions to ≤30 mg.
