The model CEJS High Voltage Electrode Steam Boiler is the proven leader with more hours of operating experience over a wide range of applications than any competitor. The CEJS electrodes are vertically mounted around the inside of the pressure vessel which enables the CEJS to produce maximum amounts of steam in a minimum amount of floor space.The CEJS operates at existing distribution voltages, 4.16 to 25 KV with exceptional efficiency - up to 99.9% efficient! Models are available to produce steam in capacities to 270,000 pounds per hour. Pressure ratings range from 75 psig to 500 psig. All CEJS boilers are designed to ASME Sec. VIII Div.1 and are certified and registered pressure vessels.

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 of one phase, through neutral, to an electrode of another phase using the water as a conductor. Since the water has electrical resistance, the current flow generates heat directly in the water itself. The more current (amps) that flows, the more heat (BTUs) is generated and the more steam produced. Nearly 100% of the electrical energy is converted into heat with no stack or heat transfer losses.

A.E.P. Thermal is offering an ACMETHERM design High Voltage Jet Type Electrode Steam Boilers for direct connection from 4.16 to 25 KV supply circuits (3 PHASE - 4 wire, grounded neutral).

  • Ratings from 2000 kW to 65000 kW (at various operating pressures)
  • 100 psig to 500 psig operating pressures available
  • Do not require step-down transformers if used at 25 KV or other H.V. line voltages
  • Simplified electrical installation through elimination of a number of components
  • Substantial final cost savings through elimination of step-down transformer, wherever possible, structure, components and associated labour costs.
  • Backed by prompt and comprehensive assistance at all levels.

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 of one phase, through neutral, to an electrode o' another phase using the water as the conductor.

Since the water has electrical resistance, this current flow generates heat directly in the water itself. The more current (amps) that flows, the more heat (BTU's) generated and the more steam produced. 100% of the electrical energy is converted into heat with no stack or heat transfer losses.

Low water protection is absolute since the absence of water prevents current from flowing and the electrode boiler from producing steam.

Unlike conventional electric boilers or fossil fuel boilers, nothing in the electrode boiler is at a higher temperature than the water itself.

If scaling should occur in the boiler, it will electrically insulate the electrodes, which reduces current flow and boiler output. There is no loss in conversion efficiency however, and, simply cleaning the electrodes will restore full boiler capacity. There can be no heat buildup in the electrodes, therefore, no electrode burnout, and no danger to the boiler itself.

The Model CEJS High Voltage Electrode Steam Boiler, is the proven leader with more hours of operating experience over a wide range of applications. The CEJS electrodes are vertically mounted around the inside 1 of the pressure vessel which enables the CEJS to produce maximum amounts of steam in a minimum amount of floor space.

The CEJS operates at existing distribution voltages, 4.16 to 25 kv with exceptional efficiency—up to 99.9% efficient! Models are available to produce steam in capacities to 270,000 pounds per hour. Pressure ratings range from 75 psig to 500 psig. All CEJS boilers are designed to A.S.M.E. Boiler and Pressure Vessel Code, and are certified and registered pressure vessels.

Water from the lower pan of the boiler is pumped by the circulation pump (1) up the collection pipe (2) to the nozzle stock (3) The water is forced through the jets of the nozzle stock to strike the electrode plate (4) creating an electrical current path (R1). The unevaporated water flows from the electrode through the nozzle plate (5) to strike the counter electrode (6). creating a second current path (R2). Control of the boiler output is accomplished by raising of lowering the control sleeve (7) which diverts the water from the covered jets directly back to the lower portion ot the boiler. I he control sleeve is moved hydraulically by the control cylinder (10) wnich, in turn, is positioned by the electronic processor boiler pressure and load control system. This control system will hold steam pressure and match boiler output to system requirements.

The stand-by heater (14) is used to maintain water temperature at a pre-set level in order to reduce start up time.

A proportioning feedwater regulator (not shown) maintains a constant water level in the boiler A load monitoring system prevents the electric demand from exceeding boiler capacity and enables the boiler to be manually set at levels lower than its full kw rating. The boiler may also be controlled by an automatic demand control system.

To shut off the boiler simply stop the circulation pump.
