Industrial Low Pressure Fire Tube 4 Ton Bunker Oil Steam Boiler for Carton Factory

I Brief intrduction

bunker oil fired boiler is Yuanda WNS series oil gas fired 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 buker oil steam boiler

3. WNS bunker oil steam boiler design features:

1. package type boiler, integrated structure, short installation time, .

2. High efficiency, the thermal efficiency can reach up to 96%-98% after install economizer.

3. low NOx 30mg emission, low pollution

4. PLC control, intelligent control, safe and easy operation,

5. Advanced CNC machining process for material cutting, rolling, drilling.reduce the assemble stress and extend boiler working lifetime.

6. Less fuel consumption, energy saving 20%.

7. Double layer 12cm aluminum silicate insulation , reduce heat loss, control the boiler body temperature below 40 ℃.

4. Safety System each part of the diesel oil 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. Minor but important detail designs:

• Designed with special steam water separator,reduce steam humidity and improve steam quality.
• Designed solid steel rod tension bars, increasing the tube plate strength, preventing cracking.
• Industrial packaging design, stainless steel outer packing, elegant and anti-corrosion.
• Low Dropout explosion proof door design, prevent explosion, reduce the damage to the boiler, improve the safety of boiler.
•  Double open door design at the front and back smoke box, beautiful appearance and convenient maintenance.
• Quick-setting high-strength fire-resistant refractory casting material with strong coagulation force, long service life and not fall off.
• Large volume for water, stable steam generation and high steam quality.
• Flow type intelligent water treatment equipment,automatic and microcomputer operation, prevent the hurt from boiler.
• Vertical type stainless steel water pump, delicate and compact structure, low power consumption, can save 50% energy than horizontal type. 

6. Diesel oil boiler auxiliary machines:

7. 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;
