Introduction

WNS series steam boiler is a kind of all wet-back, horizontal, internal combustion boiler with three return structure. Its main structure consists of boiler shell, furnace, smoke chamber, smoke tube, etc. Thanks to the design of wet back structure and corrugated furnace, symmetrically arranged heating surface, WNS steam boiler receives more reasonable strength and expansion, which ensures a good water circulation and heat exchange, achieve the best condition of the heat transfer effect, improve the thermal efficiency of the boiler; thermal efficiency can be as high as 92%.

The boiler combustion chamber of oil/gas fired steam boiler has a reasonable design, and it is fully applied to city light oil, heavy oil, natural gas, liquefied gas, city gas and other fuels, the fuel is completely burning inside the furnace in a micro positive pressure condition, which brings small flue gas pollutants, meanwhile, the flue gas blackness, boiler smoke concentration, noise and other technical indicators are superior to standards of national A class area. Moreover, the control system adopts mechatronics equipment and programmable logic controller (PLC). Furthermore, this series steam boiler is equipped with well-known Italy Riello/Baltur brand burner.

HTS steam boiler is widely used in hospitals, schools, textile factory, garment factory, printing and dyeing factory, hotels, canteens, restaurants, food plants, beverage plants, soybean plants, meat products, canned food factory, brewery, pharmaceutical factory, packing factory, building materials factory, etc.

Features

1.The unique welding technique of smoke pipe and pipe plate, it adopts the advanced technology of pre expanding before fully welding, then expanded connections, not only prevent the tube gap corrosion, but also enhance the welding strength.

2.Adopt thread smoke tube with high heat transfer coefficient, not only enhance the heat transfer effect, but also decrease the exhaust gas temperature and increase the thermal efficiency.

3.Symmetrical movable hinged front and rear smoke doors, which is convenient to open, inspect, maintain and clean.  

4.Steam boiler adopts wet back structure, full butt welding seam, high reliability, low maintenance costs.

5.Steam boiler is provided with rear view device design, which is easy to observe the combustion condition.

6. A variety of protection functions are provided with steam boiler, such as over temperature, over pressure, water shortage, leak detection, flame out and so on, hence ensures the boiler safe and reliable.

7.Steam with 1-20 ton output to meet different requirement and fit in various application range.

8. Large volume and low level layout design of boiler combustion chamber, not only improves fuel combustion efficiency, but also increases the safety water level range, minimizes the possibility of accidents caused by water shortage.

9. Steam boiler thermal insulating layer adopts aluminium silicate, which has advantages of high thermal resistance and good thermal insulation effect.
