Package Type Industrial Fire Tube Riello Burner Gas Steam Boiler
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
2.Steam Capacity: 0.5 ton/h 1 2 3 4 5 6 8 10 12 15 20 ton per hour
3.Design pressure: 0.4Mpa to 2.5Mpa. 0.7Mpa(7bar)1.0Mpa(10bar),
4.Stem temperature: 151℃, 170℃,184℃, 194℃, 204℃, 226℃
5.Design fuel:natural gas, lpg,lng,cng,city gas,biogas, diesel
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
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
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
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
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
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

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;
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.
