High Voltage Immersed Electrode Steam Boiler
Electrode boilers utilize the conductive and resistive properties of water to carry electric current and generate steam. An A.C. current flows from an electrode to one phase to the ground using the water as the conductor.
These Electrode Boilers have unlimited application possibilities wherever a need for process or space heating exists.
A partial list of possible uses includes:
- Hospitals, schools, hotels
- Caterings and Food processing
- Clothing and textiles plants
- Industrial plants
- Plastic and Chemical Plants
- Washing Utilities
- Power plants
Electrode boilers utilize the conductive and resistive properties of water to carry electric current and generate steam. An A.C. current flows from an electrode to one phase to the ground using the water as the conductor.
Electrical Requirement
CEJWS boilers are designed for use on 3 phases, 4 wires distribution (or 3 phases 3 wires with special grounding connection) to the circuit breaker. The boiler shell and cage must be grounded to the building steel and ground mat.
Key Advantages and Features
Using the water as the conductor
Electrode boilers utilize the conductive and resistive properties of water to carry electric current and generate steam. An A.C. current flows from an electrode to one phase to the grounded counter electrode using the water as the conductor.
100% of the electrical energy is converted into heat
In the section view of the boiler, water cooling flow is provided by the recirculation pump and is forced up through three jet guide pipes around the electrodes. Since the water is the electrical resistance, this current flow generates heat directly in the water itself. The more current (amps) that flows, the more heat (BTU) is generated, and more steam is produced. Almost 100% of the electrical energy is converted into heat.
The amount of the steam generated is compensated
The amount of the steam generated is compensated by the feedwater system which is added to the recirculation water flow to have more cooling effects on the electrodes. An electronic driving system is used to interpose a concentric insulating shield between the electrode and the neutral counter electrode. The movement of the shield increases the exposure between the electrode and counter electrode resulting in an increase of current between the two. The barrier shield can turn the boiler output down to about 10% or a 10:1 turn-down ratio. The supply power must be interrupted to turn the boiler down to below 10%.
HIGH PERFORMANCE
Converts virtually 99.5% of the electrical energy into heat. Rapid response (full load within 30-40 minutes from cold start or within one minute from hot start).
