Vacuum hot water boiler advantages

(1) The boiler that operates under vacuum and does not explode, has excellent safety.
(2) The successful separation of the high-temperature and high-pressure regions of the boiler steel plate has prolonged the service life of the boiler by 2-3 times, and the designed service life has reached 30 years.
(3) The overall design is scientific, reasonable and compact, saving 50-70% of the floor space.
(4) The heat exchange is carried out in the boiler body, and the efficiency of the whole machine is over 91%. It can provide hot water at 70-80 ° C within 2-3 minutes after startup, which greatly shortens the warm-up period and reduces energy waste.
(5) Fully automatic control, which can implement intelligent, unmanned operation or remote network control.
(6) Built-in stainless steel heat exchanger, no pollution to water quality.
(7) Compared with the indirect type (boiler + external displacement heat exchanger + circulating water pump + material + installation cost), the installation cost can be saved by more than 30-40%.
(8) High efficiency, fast heating, good heat exchange, saving fuel cost by more than 20-30%.
Features
Reliable and safe operation

Vacuum Boiler During the operation of the vacuum hot water boiler, the internal pressure of the furnace body is always in the vacuum state of -15CMHG-76CMHG, even if the U-type heat exchanger leaks due to external pressure or cannot be exceeded due to operating failure. In the case of outside atmospheric pressure, the controller, water temperature control, overheating switch, vacuum pressure switch will automatically cut off the power. When the pressure reaches 0.025MPa, the pressure relief valve will automatically open to discharge the pressure. Because the control of the Stavak vacuum boiler adopts advanced technology, all water level faults are automatic and low-frequency alarm. The system can automatically cut off the power and inform the user to avoid losses caused by water shortage.

long life
The vacuum boiler is because the interior of the vacuum boiler is a closed atmosphere. During operation, the oxygen in the intermediate medium is precipitated and discharged out of the furnace. Oxygen corrosion will not occur in the furnace for a long time. A small amount of heat medium water is added at one time. The calcium and magnesium ions do not increase or decrease during operation, so no fouling occurs inside the boiler, which increases the service life of the boiler, which is 1.5 to 2 times that of the general boiler. The heat exchanger is made of stainless steel tube, which is corrosion resistant and has a designed service life of more than 15 years.
Strong applicability
The vacuum boiler is formed by a special design structure, which can be used for multiple purposes in one machine. At the same time, it can provide multiple channels of hot water with different temperature differences to meet the needs of users of central air conditioning, heating, sanitary hot water, advanced swimming pools, hotels and other hot water supplies. It can also provide process water for various industrial and mining enterprises. Due to the good thermal insulation effect, the imported burner is suitable for areas with an altitude of less than 3000 meters. For heating it is through the negative pressure steam, which indirectly receives the heat from the burner. Under standard conditions, the vacuum degree in the vacuum chamber of -76CMHG decreases with the increase of the steam pressure in the vacuum chamber; when the negative pressure steam temperature of the heat medium reaches 94 ° C, the vacuum degree drops to -15CMHG. At this time, The vacuum switch is started to stop the combustion operation; as the heat exchanger takes away heat, the temperature of the heat medium and its steam decreases, and the negative pressure increases. At any time, the vacuum switch starts the burner to reciprocate in this way to achieve hot water and heating. the goal of. The vacuum degree in the vacuum chamber of the furnace is -15CMHG at the lowest and -76CMHG at the highest. The negative pressure is always maintained to ensure absolute safety. The temperature of the heat medium and the steam in the vacuum chamber can be raised to 94 degrees Celsius, so the heating and hot water temperatures can reach Above 80 degrees Celsius. The boiler body and the vacuum chamber do not bear any pressure, and the heat exchanger can bear the pressure. Therefore, the entire process from commissioning to operation does not need to be inspected, and a licensed boiler worker is not required.
Energy efficient
The vacuum boiler adopts Korean vacuum hot water boiler technology. The boiler operates under vacuum. The boiling point is low and the latent heat of vaporization (condensation latent heat) is exchanged. Improve the radiation and convection heat transfer area, the thermal efficiency of the boiler is as high as 91%.
Rich models and multiple functions
Vacuum boiler vertical, horizontal, fuel, gas, water pipe, and smoke pipe models are available for users to choose freely. The heat exchanger is separated from the header, and the load of heating water and hot water can be switched at any time as needed to meet the user's use. Different requirements for heating water and clean hot water ensure clean and stable hot water.
Compact and easy installation
The modular design of the vacuum boiler, high-performance heat exchange components, and the small size of the unit make the product easy to transport and install. In a small space, multiple units can be used in parallel.
Unique environmental features:
The vacuum boiler adopts a high-performance burner and a flame-backed structure design, and the fuel is fully burned. The environmental protection index of the boiler reaches the national tourist area emission standard.
Eliminate complicated procedures for approval:
The vacuum boiler unit operates under vacuum, which simplifies the procedures of pressure vessel approval, annual review and other procedures, and does not require a certificate for operation.
