ELECTRODE BOILERSWITH JET-FLO TechnologyVAPOR POWER INTERNATIONAL
Electrode Steam BoilersELECTRODE boilersSteam from: 3000 kW to 34,000kW (10,000 to 113,000 PPH)Pressure from: 100 – 500 PSIGVoltages from: 4160 – 14,400 VoltsHot Water Boilers with similarcapacities are also availableADVANTAGES High efficiencyGreater than 99% High turndown & QUICK RESPONSETO LOAD CHANGESSafely operate as low as 1% of outputThe Electrode Steam Boiler withJet-Flo technology consistsof an insulated pressure vesseland is fully enclosed in 18 gaugeenameled steel panels. There is noheat transfer through tube walls andthere will never be tube failures fromexcessive wall temperature, poor watertreatment, or fireside corrosion, sincethere are no tubes to fail! Heat transfertakes place directly in the water in thesteam chamber, thus producing highquality steam of 99.95% purity throughoutthe operating range.A Vapor Power electrode steam boiler offersa great hybrid boiler room solution, takingadvantage of off peak power rates. Fossilfuel fired boilers and the electrode boilerare automatically rotated based on real timepower costs, maximizing steam plant efficiency.Electrode steam boilers are available in sizesfrom 3,000 to 34,000KW, 10,000 to 113,000 PPH, Reliable source of steamFor areas affected by oil and/or gas shortages, orwhere coal is either low grade or not available No moving partsEliminates downtime due to packing leaksaround the hydraulically-operated shieldpositioning system that is present on otherdesigns. No risk of failure of internalmechanical shields. No hydraulicsystem required. LOW INSTALLATION COSTEliminates need for special boiler room, fuelhandling and storage equipment, air handlingequipment, preheaters and/or economizers,stacks, flues and emission control equipment,ash handling and disposal facilities, combustionsafety systems, noise abatement equipment,plus space and installation costs associatedwith aforementioned equipment. No EmissionsMakes for an easy installation becauseno air permits are required LABOR SAVINGSElectric boilers in most states areclassified as “unfired steamgenerators” and as such do notrequire full operator attendance No dielectric barriersneeded No special watertreatment Industrial GradecomponentsApplications Brewery & Distillation Container & Paper Processing Healthcare Facilities Power Plant Process Steam & Heat University & Institutional Facilitiessupply voltage of 4,160 to 14,400 volts, and offerefficiencies greater than 99%.23
electrode boilersThe Vapor Power electrode boiler creates operatingadvantages from its unique design which results in a highefficiency, high quality steam boiler. Using electricity as aclean, efficient and easily controlled fuel, all the energy inputto the boiler is converted to steam with 99% efficiency.Vapor Power’s electrode boiler output is controllablefrom 0-100%, with neither the limited turndown ratiosnor the increasing inefficiency at low output conditionsControlsAVAILABLE POWER: With theelectric boiler set at a slightly higherpressure than parallel fossil fueledboilers, sensing plant demand, andlimited to a maximum plant demandset point, competitively pricedavailable power can be consumed toeffect a flat demand curve.characteristic of fossil-fired boilers. There are no stacksThe electrode boiler is locally managed by a PLCbased system that controls every aspect of theboiler which includes control of water level, steampressure and KW limit. All safety devices willalso be monitored by the PLC. Interface to thePLC by an operator is accomplished throughan HMI device that communicates directly withthe boiler PLC. Remote data acquisition andcontrol is available via ModBus, Ethernet,Bacnet, or other communication protocol.Built to Meet Standardsto purchase and there are zero pollutant emissions.The simplicity of electrode controls and engineeredEvery unit is built to ASME Standards,Hartford inspected and National Boardregistered. Other approvals are alsoavailable upon request.boiler design results in significantly reducedmaintenance. With no moving parts within the boiler,there is less maintenance associated with our units.Even under the conditions of feedwater loss, forexample, the electrode boiler is fail-safe as lowwater in itself affects boiler shutdown, precludingcatastrophic failure. There is no heat transferthrough tube walls and there will never be tubefailures from excessive wall temperature, poorwater treatment, or fireside corrosion, since thereare no tubes to fail. Heat transfer takes placeBy using a 2-element control system, theelectric boiler would either generate as muchsteam as allowed by the demand controlsystem or, when steam demand is below whatthe electric boiler is allowed to generate, belimited by the steam pressure control to apreset steam pressure.directly in the water in the steam chamber, thusproducing high quality steam of 99.95% puritythroughout the operating range.4Using electricity as a clean,efficient and easily controlledfuel, all the energy inputto the boiler is converted tosteam with 99% efficiencyHot Water OptionTo generate hot water, Vapor Poweroffers a steam-to-water heatexchanger attached directly to theboiler. Outputs available range up to170,000 MBTU/Hr. The advantage ofthis system is that the condensatefrom the heat exchanger flows bygravity back to the boiler eliminatingthe need for a condensate returnor deaerator system, which alsoimproves the system efficiency.5
