The structure of Sitong WNS Series steam boiler is compact and reasonable. This boiler is composed of three parts: boiler body, chimneys and piping systems. Boiler body and chimney are manufactured in our factory, and piping systems are installed when the boiler arrives at the destination, the technical team could help to install the boiler or offer the technical support if necessary. Moreover, the quality of the boiler can be guaranteed.

Application 
Packaged fire tube boiler has compact structure and small size, it is usually used for heating and industrial process applications with small steam capacity. According to the characteristics of compact structure, safe operation, convenient installation, low pollution and low noise, the steam boiler could be used for medicine, chemical, light industry, textile, building material, cultivation, food and beverage, plastic foam, printing,dyeing and washing, rubber processing, paper products, wood processing, hotel, clothing and leather manufacture etc.

Advantages
1. Sitong patented technology
100% completely butt welding, minimum stress, and the quality is more reliable.
2. Large diameter corrugated furnace
Combustion chamber is composed by large diameter full corrugation furnace, large combustion space, sufficient combustion.
3. Enough heating power
Boiler heating area is >25㎡/ton, it can absorb effective heat sufficient, low exhaust gas temperature,small heat loss,ensure enough heating power and high efficiency.
4. High steam quality
Large steam space volume and enough height of the net distance between steam water interface and steam outlet.
5. Multi-function safety explosion proof equipment
Equipped with explosion proof equipment, which can prevent fuel occur deflagration in furnace, discharge high energy. Moreover, it has the fire sight glass and inspection gallery,
it is convenien for furnace checking and maintaining.
6. Advanced automatic control
Boiler controller use Siemens/Delixi electrical element, reliable property. Automatic control on pressure, water temperature, and smoke temperature, etc, ensure safe operation.
7. Convenient to maintenance
There is a manhole on the top of the boiler,and some special hand hold device at middle and lower position of boiler front and back end, it’s convenient for boiler
internal installation, inspect and clean.
