Package Type Industrial Fire Tube Riello Burner Gas Steam Boiler 2000kg

I Brief intrduction of gas steam boiler

Gas fired steam boiler is Yuanda WNS series boiler, it is package type full automatic horizontal three pass fire tube wet back structure boiler. The boiler can produce hot water, saturated steam or superheated steam. It’s adaptable for wide ranges of fuels such as natural gas, LPG, biogas, methane gas, diesel heavy oil etc.

2. Quick Details of WNS gas steam boiler

5.Design fuel:natural gas, lpg,lng,cng,city gas,biogas, diesel oil,heavy oil

6.Structure: three pass fire tube wet back

7.Application: boiler for textile mill, milk pasteurization,corrugated machine, sugar factory,pringting dyeing mill,medicine industry, food & beverage industry, chemical industry, garment industry, food processing industry, and wood processing industry, etc.

3. WNS gas steam boiler design features:
1. Big corrugated furnace

Adopt the advanced corrugated furnace design, the combustion chamber with large volume. It enlarged the furnace diameter and create a bigger radiant heat exchange area, so increased the boiler thermal efficiency.

2. The boiler is equipped with world famous brand burners and valves groups such as Baltur, Riello, Weishaupt, Oilon etc. , 80% configuration, making the combustion more sufficient with lower failure rate.

3. thread smoke tube technology

Strengthen the heat transfer and reduce the number of smoke tubes and boiler shell size.Reduce the thermal stress at the tube end to prevent cracking of tube sheet.

4. Wet back structure

Wet-back smoke chamber, the whole smoke chamber is inside boiler proper, directly heating water in boiler proper, greatly increase boiler heating efficiency. It can also lower the temperature of back tube

4. Safety System each part of the fired steam boiler is designed based on the safety.

1. Independently developed PLC control panel, better match our boiler operation. Siemens PLC with 10 inch touch screen and frequency transformer, more safety and easy operation.

Safety control system:

1.1 Control the burner, water feeding, pressure, exhaust gas temperature

1.2 Control the burner ignition and flame-out automatically; The burner can switch over from large fire to small fire.

1.3 Control the water feeding:

Automatic Alarm when the water level is higher or lower than normal water level, safety interlock when the water level is over-high or over-low.

When the water level is low, the boiler system will feed water automatically, when the water level is high, the boiler will stop feeding water. When the water level lower than 0 or over-high, the boiler burner flame out.

1.4 Pressure control: Safety interlock for over-high pressure.

1.5 Control the exhaust gas temperature

when the flue gas temperature is over-high, it will control the boiler alarm firstly and then the burner flame out, the boiler shutdown.

5. WNS diesel gas steam boiler system and auxiliary list:

6.Economizer

Aluminium-steel Fins with high conductivity co-efficient.

ND steel sheel to prevent the corrosion of sulfur

Aluminium Silicate insulation, release heating loss, reduce economizer outer cover temperature.

Large size heating area, adequate heating exchange area, greatly make use of heat energy of exhausted gas to heat feed water, increase boiler efficiency;

7.After-sale service:

1. provide full range of original spare parts.

2. We will send engineers to your local project site to guide the installation and commissioning.

3. Our engineers will held a training for boiler workers to ensure the safe operation.

4. Free maintenance and repair for one year and lifelong service.
