Overview

WNS gas/oil fired hot water boiler is a kind of safe and high efficiency heating equipment from Yuanda with full automatic control system, It can also be regarded as fire tube boiler, packaged boiler, three pass design boiler and eco-friendly boiler. 

This series oil gas fired boiler is horizontal structure with three pass structure, fast assembly fire tube boiler, it has compact structure, small volume, strong load adaptability and low water quality requirement. This boiler adopts wet wet back structure, it can adapt to the high temperature, and increase the radiation heat transfer area and improve the heat transfer efficiency (up to 99% thermal efficiency).

Our gas/oil fired boiler normally suitable for 300kg/h to 40ton/h, use all kinds of fuels, such as natural gas, LPG, LNG, CNG, city gas, biogas, diesel oil, heavy oil.

Advantages of Gas/Oil Hot Water Boiler:

Features of Gas/Oil Hot Water Boiler:

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.Automatic PLC control, Automatic Alarming system

Independently developed PLC control panel, better match our boiler operation, the electrical cabinet receives signals from all gauges and control the whole working system, including burner set on/off, water pump set on/off, water softener, etc.

3.Wet back structure

Wet-back smoke chamber,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.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.

5. Three-pass exhausted gas flow design

Ensure high temperature exhausted gas contacting with boiler tubes adequately, reduce exhausted gas temperature and increase boiler efficiency.

6. Double layer 12cm aluminum silicate insulation, seal tight and avoid gas leakage and minimize heat loss.
