Working Principle of Vacuum Phase Change Hot Water Boiler:
Vacuum phase change hot water boiler uses water boiling at low temperature to produce steam. It works on the principle of heat output through steam-water condensation heat transfer. Inside the unit is a closed vacuum chamber. Combustion makes heat medium water boiling and vaporizing in the vacuum chamber to produce negative pressure water vapor. Steam condenses outside the heat exchanger tube and adds cold water inside the tube. Thermal heating and access to the user, water vapor condensation after the formation of water droplets regenerative medium water is reheated and vaporized, complete the whole cycle.
Advantages of Vacuum Phase Change Hot Water Boiler
Negative pressure operation, safe and reliable, never explosion
Inspection-free, can be placed on the roof, basement
Non-scaling, long service life
Vacuum phase change hot water boiler can be used in the following situations:
Heating: residential district heating office building heating business place heating Hotel Heating factory heating
Hygienic Hot Water: Hot Water for Hygienic Hot Water in Hotels, Hotels, Business Places, Hygienic Hot Water Swimming Pool, Hygienic Hot Water Factory
Advantages of Vacuum Phase Change Hot Water Boiler in Civil Heating
The system is simple and easy to install.
Safety, no explosion risk
Energy-saving, low operating costs
Placeable roof or basement
Advantages of Vacuum Phase Change Hot Water Boiler
1. Vacuum phase change hot water boiler is operated under negative pressure environment, so it will not explode and is a national inspection-free product.
2. Successful separation of high temperature zone and high pressure zone of the steel plate under the pressure of the boiler 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 area.
4. Heat exchange in the main body of the boiler, the efficiency of the whole machine is up to 91%. Hot water at 70-80 C can be provided within 2-3 minutes after start-up, which greatly shortens the preheating period and reduces energy waste.
5. Fully automatic control, which can be intellectualized, unmanned or remote network control.
6. Built-in stainless steel heat exchanger, no pollution to water quality
7. Compared with indirect heating (boiler + external heat exchanger + circulating water pump + material + installation cost), installation cost can be saved by more than 30-40%.
8. High efficiency, fast heating, good heat transfer, saving fuel costs by more than 20-30%.
The service life of vacuum phase change hot water boilers is 2-3 times that of other types of boilers. Generally, it has a service life of 20-30 years.
