7 ton Light oil or heavy oil  Natural gas fired steam water boiler

Steam boiler is a closed vessel in which water is heated. The heated water exits the boiler for use in various process or heating  applications.
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 instead.

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 protections.
6. Fiberglass heat preservation: low surface temperature and heat loss.
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 inspection.
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.
13. A economizer is optional and possible to save 10% fuel and decrease noise 20dB.
14. Applicable fuels: gas, oil, dual fuel.
15. Amended dimensions for export containerization to save shipping cost.
