WNS series steam boiler adopts three-return structure, large volume design of combustor, making combustion more sufficient. The corrugated furnace tube structure not only increases the heat transfer area, but also satisfies the free expansion of the furnace tube after heating. Designed water shortage, leakage detection, flameout and other protection functions, boiler operation is safe and reliable. Energy saving steam boiler has high thermal efficiency, stable output and strong load adaptability.
This series of steam boiler smoke pipe adopts threaded structure to enhance heat transfer effect. The rear view device is designed to facilitate the observation of combustion conditions. The boiler adopts wet-back structure, full bevel butt-weld, high reliability and low maintenance cost. Equipped with imported burner with good automatic control, it realizes full automatic operation.
The fuel of the energy saving steam boiler is slightly positive pressure combustion in the furnace bile. The high-temperature flue gas passes back through the furnace bile and enters into the first flue tube bundle. After the compression of the front smoke box into the second tube bundle, after convection heat transfer into the atmosphere. The three-return steam boiler with large capacity is designed by using the design idea of three-return structure with symmetrical center. The design of this series of steam boilers mainly considers the principle of boiler maintenance and stability. The mixed water device installed at the inlet of the boiler feed water should first flush the smoke tube bundle and then contact the furnace bladder to improve the water temperature of the water supply contact furnace bladder.
The overall design of WNS series steam boiler is reasonable, which avoids the phenomenon of supercooled boiling locally. Steam boiler to achieve the maximum vaporization space, coupled with the use of reasonable and advanced steam separation equipment, so that the steam quality is quite stable. The steam boiler pipe is connected with tube plate by expanding first and then welding, which eliminates the corrosion problem, prolongs the service life of the boiler, and improves the heat transfer coefficient of the boiler.
WNS series industrial boilers are strictly prohibited from overload, overpressure and overtemperature use. In case of abnormal pressure, water level or temperature, stop the furnace in time for inspection. This series of steam boilers adopt imported combustion machine, complete combustion, coupled with the shape characteristics of our carefully designed corrugated furnace and the shape of the flame quite match, can be fully developed flame. Boiler adopts micro positive pressure combustion, combustion is more intense.
Energy saving steam boiler operation automation, program control ignition combustion. It also has automatic replenishment water, water level three protection, steam three-level overpressure protection, flame-out protection, gas leakage protection. The whole process is automatically controlled by computer. The operation is simple, the noise is small, deeply obtains the user favor. Zozen Boilers products specializing in the production of high quality boiler, welcome everyone to come to consult procurement, we will serve you wholeheartedly.
