E-BOILER IMMERSION-TYPE ELECTRODE STEAM BOILERS

HIGH ELECTRICAL STABILITY

· e-Boiler Electrode Steam Boilers have no problems with foaming and arcing, because of the design, the requirement for demineralized make-up water, the strict control of boiler water conductivity and chemical additives. 

· e-Boiler’s Electrode Steam Boilers have an electrically insulated neutral point (the inner vessel), with a high resistance to earth, which limits  the current  to earth at a short circuit between a phase and neutral point to approximately 5A, therefore allowing our boilers to be connected directly to the common electrical grid -  without using a dedicated, directly earthed,  transformer.

HIGH STEAM QUALITY AND PURITY

· e-Boiler’s boilers are designed with steam quality in mind, with a large steam space and water surface (similar to fire-tube boilers) and low steam velocity that minimizes water droplet formation.

· The steam’s quality and purity are high enough to be used as gland sealing steam in turbines in Nuclear Power Plants with a requirement for a sodium content of less than 5 ppb.

· Due to our strict control in boiler water quality, we can assure a high steam purity with a low salt content in the steam (which otherwise can cause corrosion, coatings and other problems in connected equipment).

HIGH RELIABILITY

· The only major moving parts in our system are our circulation pumps and we can provide redundancy in the circulation system to maintain a near 100% uptime.

· Immersion-type Electrode Steam Boilers are simple in concept and in operation and do not have complicated nozzle arrangements present as in jet-/spray-type boilers that quickly wears out and require frequent maintenance to function optimally.

· e-Boiler meet the strict reliability requirements as dictated by Europe’s largest nuclear power plant operators.

EASE OF MAINTENANCE

· e-Boiler has long-life and low-maintenance electrodes and ceramic insulator designs and do not require external cranes to remove and service the boilers.

HIGH EFFICIENCY

· e-Boiler utilize blowdown recovery device to minimize energy loss due to blowdown. The overall efficiency, including blowdown losses, is more than 99.9%.

· Immersion electrode boilers can operate from 2% to 100% power level with the same efficiency of close to 100%.
