high pressure 3 tons Gas/Oil fired steam boilers for sale
Steam boiler is a closed vessel in which water is heated. The
heated water exits the boiler for use in various process or heating
The pressure vessel in a boiler is usually made of steel (or alloy
steel), or historically of wrought iron. Stainless steel is
virtually prohibited (by the ASME Boiler Code) for use in wetted
parts of modern boilers, but is used often in superheater sections
that will not be exposed to liquid boiler water. In live steam
models, copper or brass is often used because it is more easily
fabricated in smaller size boilers. Historically, copper was often
used for fireboxes (particularly for steam locomotives), because of
its better formability and higher thermal conductivity; however, in
more recent times, the high price of copper often makes this an
uneconomic choice and cheaper substitutes (such as steel) are used

1. Reliable three-pass and fully wet back structure.
2. Lateral-cut tube technology: increase heat efficiency.
3. Big combustion room design: increase radiated area, decrease
emission of NOx, and reduce boiler cubage.
4. Big flue gas tube: reduce the resistance of smoke flow and
consumption of electricity.
5. Intelligent control system: PLC and 5.7 touch panel, multi-level
6. Fiberglass heat preservation: low surface temperature and heat
7. Corrugated hearth: more safety and increase heat convection.
8. Multi-level sealing for flue gas chamber: no flue gas leakage.
9. Each boiler is subject to strict inspection and testing before
delivery, including hydraulic pressure testing and X ray
10. Selecting the most suitable burner to match the boiler so as to
guarantee safety and reach rated output.
11. Main components, such as burners, pumps, water level meters,
valves are limited to renowned brands.
12. Stainless steel plate protective cladding for surface: fine
appearance and effective protection.
