WNS series gas-fired(oil-fired) hot water boiler

WNS series gas-fired(oil-fired) hot water boiler


1, WNS series automatic fuel, gas hot water boiler adopts international classic structure. The combustion chamber adopts a corrugated furnace and is arranged at a low position, which effectively increases the heat exchange area and enhances the turbulent heat transfer of the high temperature flue gas. It also mitigates the shortevity of equipment life caused by thermal expansion and contraction.

2, the three-return structure of the pipe is symmetrically arranged to ensure the best heat exchange area and heat transfer efficiency, and the whole wet back arrangement ensures the safe operation of the boiler equipment and reduces the loss caused by maintenance.

3, boiler control uses fully automated operation, computer program control combustion automatic adjustment. The steam boiler has the functions of self-controlled ignition and flameout of water level, automatic protection of high and low water level steam overpressure. The hot water boiler has functions such as over-temperature, over-pressure and ultra-low-pressure alarm protection to ensure safe operation of the boiler combustion.

4, The boiler is equipped with internationally advanced imported burners, which have high combustion efficiency (more than 86%), and the smoke and dust emission meets the requirements of the national environmental protection category I area (landscape protection area). Regardless of all types of industrial and mining, hotels, hospitals, enterprises or shipping, the company's products will meet your needs.


Oil and gas fired boilers are both oil and gas fired boilers. The WNS horizontal full-automatic oil and gas fired hot water boiler is a horizontal fast installed internal combustion three return fire tube boiler. It adopts a wet-back structure of bias furnace gallbladder. The high-temperature flue gas washes the second and third return flue pipes in turn, and then discharges into the atmosphere through the chimney through the back flue chamber. The boiler is equipped with movable front and rear smoke box cover, which makes the boiler easy to maintain. The boiler is equipped with an industrial burner with good technical performance. It adopts advanced technologies such as automatic combustion proportional regulation, automatic feed water regulation, program starting and stopping, automatic operation and so on. It also has automatic protection functions such as high and low water level alarm, ultra-low water level, ultra-high steam pressure and flameout.

This type of boiler realizes the advantages of sufficient combustion, no pollution, convenient operation and convenient installation. This type of boiler has high thermal efficiency, large output, strong load adaptability, high degree of automation, convenient operation and safe operation. It is an ideal green product with high efficiency, low consumption and low pollution.
