Characteristics of fuel (gas) vacuum hot water boiler

1. A vacuum boiler operates under vacuum negative pressure and is equipped with a mechanical overpressure rupture port on the furnace body, making it a truly non explosive boiler with excellent safety.

2. The Quanxin vacuum furnace body adopts a horizontal three pass wet back structure with a symmetrical center arrangement, which can improve the stress distribution of the tube plate. The wet back structure combustion chamber and smoke pipe are completely immersed in water, with good cooling conditions. The design of a large combustion chamber is conducive to the spread of combustion flames and sufficient combustion.

3. Operating in a vacuum state, with a low boiling point and latent heat of vaporization (condensation) for heat exchange, effectively improving thermal efficiency.

4. There is a constant amount of heat medium water stored in the furnace, and the injected heat medium water operates in a closed state without corrosion or scaling, making its service life about twice as long as ordinary boilers, up to 20 years.

5. Built in specially treated stainless steel or copper heat exchangers, assembled with flanges for easy maintenance; Good heat exchange effect and fast heating.

6. The heat exchanger is separated from the header, and the heating water and hot water are supplied separately to meet the different needs of users for heating water and clean hot water.

7. Heat exchange is carried out in the boiler furnace with high efficiency. The overall design is scientific, reasonable, compact, and saves 50-70% of the floor area.

8. Users do not need to undergo annual inspection and approval according to boiler pressure vessel standards, saving costs.

9. By applying advanced digital control technology, the operation process can be remotely and accurately monitored. The controller adopts LCD or touch screen controller, with high degree of automation, easy operation, automatic control of heating, water level, pressure, overpressure, water shortage protection and other interlocking protection functions. Chinese and graphic display system operating conditions, online operation guide, and fault self diagnosis for the control part. Fully automatic operation with manual operation allows for one use and one backup, enabling human-machine dialogue.
