WNS type automatic horizontal steam boiler is a horizontal quick - mounted internal - burning three - return - trip fire tube boiler.The bifurcated flue gas is used to wash the second and third return flue gas pipes successively, and then the flue gas chamber is discharged into the atmosphere through the chimney.The boiler is fitted with movable front and rear smoke box covers to facilitate boiler maintenance.

Performance Features:

1. Boiler design

Horizontal internal combustion three return journey full wet back design, 100% corrugated furnace, with good thermal retrability, water cooled retrorse chamber, retrorse chamber and back tubeplate butt joint, lowest stress, more reliable quality.

2, large diameter corrugated furnace

The boiler combustion chamber is composed of a large diameter full ripple furnace with large combustion space, complete fuel combustion, effective heat absorption and thermal expansion, and large radiation heating surface.

3. Sufficient heat

The heating area of the boiler is designed to be more than 25 square meters/ton, fully absorbing effective heat, low smoke exhaust temperature, small heat loss, ensuring sufficient output and high efficiency.

4. Steam quality

Pot shell diameter, large water capacity, strong adaptability to load changes, stable output, steam space volume, soda interface and steam outlet net distance is high, low steam humidity.

5. Multi-functional safety and explosion protection device

The back plate of the boiler is equipped with the explosion-proof device which is connected with the furnace to prevent the high energy of the discharge moment when the fuel is violently deflated in the furnace, and it can automatically reset. Meanwhile, it has the function of the fire-viewing mirror and the maintenance channel. It makes use of the adjustment of the burning flame in operation, and makes the furnace inspection and maintenance convenient.

Executive Standard

1. Design, manufacture, assembly, experiment and acceptance of boilers in strict accordance with national and industrial standards, including but not limited to the following standards: GB/T16508 Boiler Shell Boiler, TSG G0001 Boiler Safety Design Supervision Code, GB50273 Boiler Installation Engineering Construction and Acceptance Code

2. The main steel used in the boiler is 20 GB/T3087, which ensures the safety and reliability of the boiler.

3. Welding materials shall be selected according to NB/T47018. Full penetration welding with argon protection shall be performed on the boiler tube.

Technical parameter

What are the available fuel for the oil gas fired boiler?

Oil gas fired boiler could burn both liquid fuel and gaseous fuel. The liquid fuel could be heavy oil, light oil, diesel, furnace oil, bunker oil, LPG (liquefied petroleum gas), etc. The gaseous fuel could be natural gas, city gas, bio-gas, etc.

Whether the boiler can burn dual fuel or multi-fuel?

Steam boiler have oil burner, gas burner, and oil&gas dual fuel burner, we can offer the specific burner based on customers’ requirement.

What is the texture of spirally corrugated tube?

The texture of spirally corrugated tube is 20#.

The brand of burner?

The brands of burner are Italy Baltur, Rellio, Elco, etc.

What is the thickness of combustion chamber?

the thickness of corrugated furnace is different based on working pressure and furnace diameter, generally, the thickness is between 10~18mm, large combustion space, and combustion sufficient.

What is the advantages of fire tube boiler?

This fire tube boiler has compact structure and convenient operation, strong load adaptability, lower water quality requirement, and the failure rate of it is lower than 0.1!

Details of electric control cabinet.

Electric control cabinet adopts PLC touch screen, display in English. It shows working condition details of boiler, such as water temperature, water pressure, exhaust gas temperature, and over-pressure alarm, etc. In addition, the cabinet is used for set up the parameter, record and analyze the operation data, etc.

What is the inlet pressure of gas burner?

The inlet gas pressure is different for different capacity boiler, for example, the pressure for 2 ton steam capacity boiler is about 8~10KPa, while for 4 ton steam capacity boiler is about 18~20KPa.

What is the combustion mode of oil gas fired boiler?

The combustion mode of oil gas fired boiler is chamber combustion. Together with air, the powered fuel (solid fuel - coal dust), atomized fuel (liquid fuel - oil), and vaporized fuel (gas fuel - natural gas) is sprayed into furnace (combustion chamber) for suspension combustion.
