Operating pressure is typically ≤ 1.0 MPa, but heating temperature can reach 280-320℃ (liquid phase).
2. Wide range of fuels, environmentally friendly and cost-effective.
Fuel options include wood, sawdust, biomass pellets, rice husks, fruit shells, etc.
3. Compact structure, small footprint.
Vertical cylindrical structure, modular design, separate upper and lower sections, easy transportation and installation, short cycle time.
Smaller footprint than horizontal boilers, suitable for small spaces.
4. High thermal efficiency, energy saving.
Utilizes three-pass/S-type dense coils, ample radiant and convective heating surface.
Can be equipped with an economizer/air preheater to reduce flue gas temperature, resulting in high overall thermal efficiency.
5. Reliable operation and simple maintenance.
Sufficient expansion of the heating surface, less prone to coking, less ash accumulation.
No water treatment required for the heat transfer oil, no leaks, minimal maintenance.
Automatic temperature control, over-temperature/over-pressure/flameout protection, and comprehensive safety devices.
6. Precise temperature control and strong adaptability.
Automatic temperature control ensures uniform and stable heating.
Suitable for processes requiring 150–320℃ where open flame heating is not permitted: wood, chemical, textile, food, asphalt, rubber, etc.
