700kw 1400kw 2800kw 4200kw oil or gas fired hot water boiler

1. Introduction of 700kw 1400kw 2800kw 4200kw oil or gas fired hot water boiler

Automatic WNS boiler is a kind of horizontal, three-pass, wet back, fire tube boiler. Wet back means the back of furnace is surrounded by water, then the temperature of tube plate will be much lower.  Normally the rated capacity of WNS series boiler is less than  or equal to 20tons and  rating pressure is less than 2.0MPa.

3. Advantages of 700kw 1400kw 2800kw 4200kw oil or gas fired hot water boiler    

1).Adopt the latest international technology of big volume combustion design and deploy world famous burner, making the boiler has more fully burning, higher efficiency and lower failure rate.

2).Adopt the advanced structure of corrugated furnace. On one hand, it increases the heat-transfer area. On the other hand, it can bear the free expansion of furnace after heating. 

3).Adopt thread smoke tube, which can enhance heat-transfer and eliminate welding stress. 

4).Adopt double seal structure with the back of inner seal surrounded by water, which makes the boiler more reliable and maintenance costs lower.

5). All kinds of protective functions, such as over-temperature, over-pressure, water shortage, leak checking, flame-out and so on,ensuring safe and reliable operation of boiler.

Our products are not only well-known in China, but also well sold in more than 50 countries all around the world.
