What is a Jet Type Steam Boiler?
A Jet Type Steam Boiler is an advanced industrial electric steam boiler that generates steam by directing precision-controlled water jets between energized electrodes. As electrical current passes through the conductive water, heat is produced instantly, converting water into steam without burners, heating elements, or combustion.
Unlike traditional steam boilers, Jet Type Steam Boilers convert electrical energy directly into usable steam with exceptional efficiency while providing rapid response to changing production demands.

Frequently Asked Questions
How does the CEJS jet-type electrode steam boiler achieve up to 99.9% efficiency compared to conventional fire-tube steam boilers?
The CEJS series passes electrical current directly through feedwater via vertically-mounted electrodes, converting energy into steam through resistive heating with virtually zero thermal losses. Unlike fire-tube boilers where flue gases carry away 10–20% of combustion energy, the CEJS has no flue, no exhaust, and no combustion process — making near-total energy conversion physically achievable. For high-volume steam users, this efficiency advantage compounds significantly over a full operating year.
What steam pressures and output capacities does the CEJS handle?
The CEJS series operates across a pressure range of 75–500 psig and can generate up to 270,000 lbs/hour of steam — covering the full spectrum from small process steam loads to large-scale industrial and district energy applications. All units are built to ASME Section VIII Division 1 standards and are available in configurations matched to your site’s voltage, grid connection, and steam demand profile.
Why is the CEJS particularly suited for healthcare and pharmaceutical facilities with stringent process steam requirements?
Sterile process steam in healthcare and pharma environments demands consistent quality, zero combustion byproducts, and reliable uptime. The CEJS produces clean electrical steam with no risk of combustion contamination, operates silently, and eliminates the need for flue routing or gas supply infrastructure — simplifying compliance with Joint Commission standards and GMP requirements. The absence of combustion also removes CO2 and NOx from occupied spaces, a critical safety factor in clinical settings.
Does AEP Thermal’s CEJS design eliminate the electrode burnout risk seen in older electric steam boilers?
Yes. The CEJS jet-type configuration continuously cools electrodes through circulating water flow, preventing the localized overheating that causes electrode degradation in rod-type designs. This is a deliberate engineering improvement over legacy electrode boiler designs. The result is a significantly extended electrode service life, reduced cleaning frequency, and lower unplanned downtime — a meaningful operational advantage in 24/7 industrial environments.
