Electrode Steam Boiler
What is Electrode Steam Boiler – HTE Series
Hi-Therm Non-IBR Electrode Steam Boiler HTE series is a packaged compact steam generator for high pressure steam applications in small-medium scale industrial process heating.
The Hi-Therm electrode steam boiler generates steam by passing electricity through specially designed electrodes which are directly immersed in water. This passage of current through water which has certain conductive and resistive properties, causes a rise in the temperature of water. This steam generator delivers a cleaner, safer and an exceptionally high efficiency alternative for steam-based heating applications.
The packaged unit has an insulated SS boiler pressure vessel with special alloy electrodes, feed water pump, ampere-pump controller, pressure and temperature controllers, steam valves, safety valves, drain valves and electrical accessories. All these components are packaged together on a common skid, prewired, mechanically complete and tested making it ready-for-operation.
Why Choose Electrode Steam Boiler HTE Series
Zero Combustion, Zero On-site Emissions
Suited for small-medium scale applications without the hassles of pollution norms
Non-IBR design with smaller volumetric capacity
Designed for low volume, high pressure industrial processes where IBR certifications are to be avoided
Lower maintenance & safer compared to fuel-based boilers
These steam generators removes combustion related maintenance & hazards
Packaged compact design & silent operation
Simply keep it next to the point of use with no dedicated boiler room requirement
High working pressure & adequate steam output
Delivers up to 185°C temperature steam at 10 bar working pressure and up to 200 kg/hr steam flow rate
Exceptionally high efficiency with rapid response
Converts >99% of electrical energy into heat with instant full load steam within 5 mins from cold start
Steady dry steam supply
Excellent steam dryness with consistent steam output is achieved through vertical design and a large steam space
ELECTRODE STEAM BOILER – CONSTRUCTION & OPERATION
The HTE series electrode steam boilers are designed and manufactured for high pressure steam with SS 304 MOC pressure vessels. The heavy duty electrodes are of SS 316 MOC, designed for long life.
The pressure vessels are designed for 1.5x rated working pressure as per standard engineering practices and are subjected to hydrostatic pressure test under a quality control inspection to ensure strength and no leaks.
Hi-Therm’s microprocessor based Pump-Ampere Controller makes the boiler fully automatic and ensures safe operating conditions. This serves a dual function, that of controlling the water level inside the steam generator and of limiting the maximum current being drawn by the unit. The controller can be set at desired level of operating current in steps of 20%. Unlike conventional water level controllers which work within two fixed water levels inside the steam generator, the ampere controller has a unique design and works on the basis of the total current being drawn by the steam generator, irrespective of the level of the water inside the steam generator.

An electrode boiler differs in its operating principle from any other method of heating water or producing steam. The passage of electricity through any resistor causes a rise in the temperature within the material. The electrode boiler applies the same principle. The passage of electricity through water causes a rise in the temperature of water.
The electrode steam boiler generates heat inside the water. This is different from immersion heater boilers wherein the resistive heating element transfers heat to the water. The heat generated in this boiler is equal to the electricity consumed. Therefore, there is no energy loss in this process.
