Features of 15t gas fired hot water boiler:
1. Adopting tried and tested three-pass and wet-back structure, more safe andreliable
2. Big combustion room design: Increase furnace radiant heating area,decrease the boiler size, reduce the emission of the NOx
3. Corrugated hearth make the boiler more safe
4. Threaded tube: Strengthen the heat transfer, increase the boiler heatefficiency
5. Multi-level sealing for flue gas chamber: No flue gas leakage
6. Boiler controlling system can run for a long time under high temperatureand high humidity condition
7. Multi-level protections like boiler pressure, hot water temperature, gaspressure protection and so on.
8. High efficient thermal insulation material, low boiler surfacetemperature, the heat loss can be neglected
