PLC Automatic Control 4000kghr Diesel Oil Fired Steam Boiler for Corrugator Machine

I Brief intrduction 

Diesel oil fired boiler is Yuanda WNS series oil gas fired boiler, It’s adaptable for wide ranges of fuels such as natural gas, LPG, biogas, methane gas, diesel heavy oil etc. The boiler has a large corrugated furnace which have big radiate heating area and we adopted threaded smoke tube which greatly increased the boiler heat transfer efficiency. The boiler burners and valve groups are world famous brand from Italy and German, quality is stable and reliable.

2. Quick Details of buker oil steam boiler

3. WNS diesel oil 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 sheet to prevent cracking. And also extend boiler life and reduce maintenance costs.

.

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;

8. Yuanda boiler 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.
