The Horizontal Electric Steam Boiler is an industrial electric steam generation system designed for facilities requiring clean, stable, and continuous steam without combustion emissions. Available in capacities from 0.5 to 10 t/h, it is widely used in food processing, pharmaceutical manufacturing, electronics, chemical production, hospitals, and other industrial processes where precise steam control and high steam quality are essential.
Key Technical Advantages
Stable High-Dryness Steam Output
The horizontal vessel provides a larger steam-water separation space than vertical designs, producing saturated steam with a dryness fraction of up to 99% for process applications requiring consistent steam quality.
High-Efficiency Electric Heating
Immersion heating elements transfer electrical energy directly into the water, eliminating combustion losses and achieving thermal efficiency of up to 98.5%.
Automatic Output Matching
Independent heating groups are automatically switched according to real-time steam demand, helping maintain stable pressure during changing production loads.
Service-Friendly Heating Elements
Flanged heating element assemblies can be removed individually for inspection or replacement without dismantling the pressure vessel, simplifying scheduled maintenance.

Operating Performance
Designed for industrial production environments, the boiler delivers stable steam pressure under fluctuating process loads while requiring no combustion air system, chimney, or fuel storage. Automatic PLC control enables unattended operation and continuous steam supply for 24-hour production schedules.
Installation Requirements
The boiler is designed for indoor industrial installation and can be integrated into new or existing steam systems. Customers should prepare electrical power, feedwater supply, steam piping, drainage, and adequate maintenance clearance before commissioning.
Optional skid-mounted systems are available for simplified site installation

FAQ
Q: How do I select the right steam capacity?
A: The required steam capacity depends on your production process, operating pressure, and peak steam consumption. We can recommend an appropriate model based on your process requirements.
Q: Can this boiler replace an existing gas or diesel steam boiler?
A: Yes. Electric steam boilers are commonly used to replace fuel-fired boilers in facilities with sufficient electrical capacity, particularly where clean operation or emission reduction is required.
Q: Does the boiler require a chimney or exhaust system?
A: No. Because no combustion takes place, the boiler operates without flue gas, burners, fuel storage, or chimney systems.
Q: What utilities are required before installation?
A: Typical requirements include electrical power, treated feedwater, steam piping, drainage, and sufficient maintenance access around the boiler.
Q: What maintenance is normally required?
A: Routine maintenance mainly includes heating element inspection, water level control checks, safety device testing, and periodic blowdown according to operating conditions.
Q: Can the boiler operate continuously?
A: Yes. The system is designed for continuous industrial steam generation and automatically adjusts heating output according to steam demand.
Q: Can the boiler connect to our factory control system?
A: Yes. Standard communication protocols allow integration with PLC, DCS, or SCADA systems for centralized monitoring and operation.
Q: What documents are supplied before shipment?
A: Each boiler is delivered with operating manuals, electrical drawings, inspection reports, pressure test certificates, material certificates, and other documents specified in the purchase contract.
