product description


WNS series full-automatic fuel (gas) steam boiler (utility model patent) adopts a horizontal three-return wet back structure, which improves the boiler operating environment and the boiler combustion efficiency and service life.

All the flue gas channels of the boiler are placed in the water, and the tail is equipped with a waste water tank and a perfect thermal insulation outsourcing design. The sealing of the smoke box adopts a labyrinth structure, which avoids the occurrence of smoke leakage from the smoke box.

The boiler thermal efficiency is as high as 90% or more, and a combination of a corrugated furnace tube and a conical furnace tube with good expansion performance is adopted. The size of the furnace bladder matches the flame, and the area of flue gas flow is reduced in turn, so that the flue gas flows at the same speed, which ensures the heat exchange time of the high temperature flue gas in the furnace and achieves excellent heat transfer effect.

High-performance burner with fully automatic adjustment fully matched to the boiler. The burner burns fully and saves fuel, thereby effectively reducing the pollution caused by the combustion of the boiler to the environment.

The use of ultra-fine glass wool with high thermal insulation performance reduces heat loss.

Using intelligent energy-saving control system, the boiler and steam supply (water supply) system can combine different loads to adjust the fuel supply to achieve more energy-saving purposes.

The installation of the boiler adopts the overall quick installation method, which has no special requirements on the foundation, does not require anchor bolts, and is easy to install.

Adopting the movable burner structure, not only can match various burners, but also it is more convenient and quick to replace the burner and repair the furnace body.

The front and rear smoke boxes adopt removable removable structure, which can conveniently inspect, maintain and maintain the interior of the boiler.

This type of boiler is a newly developed new automatic fuel (gas) steam boiler with novel product design, reasonable structure and good process performance.

working principle

WNS series full-automatic fuel (gas) steam boiler (utility model patent) adopts a horizontal three-return wet back structure to improve the boiler operating environment, improve boiler efficiency and service life; all flue gas channels are placed in water, and the tail is equipped with residual hot water The design of the box and the perfect thermal insulation outsourcing, and the sealing of the cigarette box adopts a labyrinth structure to avoid the leakage of smoke from the cigarette box. The working principle is shown in the following figure:

Performance advantage

1.The design, production and supervision of boilers are strictly in accordance with the "Steam Boiler Safety Supervision Regulations", JB / T 10094-2002 "General Technical Conditions for Industrial Boilers", and JB / T 1609-2002 "Technical Conditions for the Manufacture of Boiler Shell Boilers" 》 Implementation to ensure long-term safe and stable work of the boiler.

2. The body is a pan-shell type full-wet back-flow three-pass pyrotechnic tube structure. The flame is burned in a large positive combustion chamber with slightly positive pressure, fully extended, and the combustion heat load is low. Low NOx emissions of harmful substances.

3. The structure of the corrugated furnace tube and the threaded flue pipe not only improves the strength, but also meets the needs of thermal expansion of each part.

4. The main welds are welded using butt joints, and no damage is detected by X-ray and ultrasonic to ensure that the welding quality meets national requirements.

5. The boiler has a large water capacity and a strong ability to adapt to loads. The reasonable design of the boiler device ensures that the water content of the steam is lower than 4%, which meets the higher requirements of users for the quality of steam.

6, using new type of thermal insulation materials, light weight, less heat loss, good thermal insulation performance.

7. The water level alarm uses stainless steel as the electrode rod and polytetrafluoroethylene as the insulating material. Inserted from above, not easy to hang dirt, reliable performance and long service life.

8. The front and rear smoke boxes are hinged, which can be easily opened, and convenient for maintenance.

9. Oxygen content adjustment (optional): The system can successfully detect the oxygen content in the flue gas and transmit the data to the control system in real time. Through the intelligent analysis of the computer, the proportion of the combustion equipment can be automatically adjusted to make it real time. In excellent working condition, the combustion efficiency is greatly improved, which can greatly reduce the fuel consumption.

10. Automatic control level The leading boiler controller adopts Siemens and Delixi electrical components, which not only has reliable performance, but also realizes man-machine dialogue and remote control.
