High-Power Electrode Boiler
Rated Steam:
4 - 90 ton/h
Rated Hot‑water:
1.4 - 42 MW
Design Pressure:
≤ 6.3 Mpa
Voltage:
6 - 22 KV
Thermal Efficiency:
99%
Application Industries:
Widely to district heating, power‑grid peak‑valley regulation, new‑energy heat storage, industrial heating, public buildings, clean‑energy retrofit and emergency heat‑supply.
Technological Advantages:
Intelligent unattended operation, wide load regulation, off‑peak heat‑storage, compact structure, easy installation.
Product Introduction
High-power electrode boilers include two types: electrode steam boiler and electrode hot water boiler.

The high‑voltage electrode boiler series immerses high‑voltage electrodes (6‑25 kV) into conductive water. Leveraging water’s conductivity and thermal‑resistance properties, it directly converts electric energy into thermal energy at efficiency above 99%.
Core Advantages
- Ultra‑high Efficiency: 99% energy conversion, zero pollution & noise‑free.

- Peak‑valley Shaving: Off‑peak heat‑storage mode for automatic grid peak‑load adjustment.

- Compact Structure: Small footprint, light weight, ample output & high safety.

- Unattended Operation: Fully‑automatic on‑demand heating, no staff on duty required.

- Cost‑effective Deployment: Easy installation, simple foundation, low investment & easy maintenance.
