10KV Electrode Phase Transition Boiler Hot Water 1.4MW 497m3/h

Operation principle -Electrode phase transition boiler for hot water, is a type of electrode vacuum / micro pressure phase transition boiler, it can produce hot water or steam. The input high volt power: 10 kV.

Operation principle
The electrode phase transition boiler (hot water), is a type of electrode boiler. The phase transition happens
inside the boiler to realize heat exchange. It consists of: electrode tube, media tank, heat exchanger, and
control cabinet. The 3PH electrodes are fixed in the electrode tubes, which are immersed into media water
with minimal conductivity. When the electricity is power on, the media water will be directly heated. The
current is transformed into thermal, so media water is quickly gasified and function as media steam, which will
rise to heat exchanger, so the thermal is transferred to the thermal supply water inside the heat exchanger
tube. Simultaneously, the media steam will be condensed then drop back to media water tank. One complete
process has been finished. The media water will repeat this phase transition process:
gasification-condensation-gasification during the boiler running time, to realize the transition from electricity
into thermal. The thermal supply power is decided by the immerse depth of electrode into the media water,
whose adjustable range: 1%-100%.
Temperature of thermal supply water(≤110ºC): electrode micro-pressure/phase transition boiler(free
from supervision and inspection); Temperature of thermal supply water(>110ºC): electrode pressure
transition boiler.Key features
1. Constant conductivity simplified
The media water is filled in one time, circulating in the closed chamber, no contact with external. Consequently, there is no electrochemical corrosion, hence constant conductivity can be ensured; No needs of conductivity adjusting system, on-time monitor. More easily operation.
2. Fixed electrode modular safe and reliable
Innovative electrode design, be made of composite materials, precisely laser positioned. No moving parts, only a small canned pump for adjusting media water level, super reliable.
3. Phase transition heat exchange simplified
Built-in heat exchanger, directly connected to the thermal supply system, no need external heat exchanger. Save the cost of one-time circulation pump, plate heat exchanger, greatly simplify the system, minimize initial investment and floor area, much higher efficient.
4. Thermal store system freely switch
The two built-in heat exchangers for the thermal supply or thermal store, can freely switch among: supply thermal, store thermal, or simultaneously supply and store thermal even without electric valve.
Technical dataNote:
1. High voltage: 10kV/50Hz/3PH. Cable specification: ZR-YJV-8.7/15-1*X(single core: X sectional area), should be ready to be connected to boiler's electrode and prepared by client.
