WNS Gas(or oil) Fired Boiler

Boiler with oil / gas burner | Oil gas fire tube boiler | Oil gas fire tube boiler

WNS oil/gas boiler series is the packaged 3-pass wet back fire tube boiler, can produce steam or hot water. This boilers are fully automatic, safe and designed to operate on a wide range of liquid and gaseous fuels like heavy oil, light oil, gas, and dual fuel options.

Output: steam
Thermal Capacity: 0.2-40 ton/h, 15hp-2500hp
Styles: horizontal
Available Fuel: natural gas, LPG, heavy oil, diesel, dual fuel etc
Applied Industries: food, beverage, feed mill, textile mill, paper mill, packaged, refinery, chemical, pharmaceutical


  • WNS series boiler is a horizontal type industrial boiler, equipped with world famous burner, can using natural gas, LPG, biogas, diesel oil or waste oil as fuel to power boiler, then generat steam for factory use.

  • WNS steam boiler capacity from 0.3t/h to 40 t/h. It has high steam quality with wetness below 1%. Steam pressure from 0.4mpa to 2.5mpa.


  • WNS gas/oil boiler is the packaged type steam boiler. It has advantages: "first furnace tube pass" "second fire tube pass" "three fire tube pass", "fully wet back & reversal chamber", "large corrugated furnace" and "patented thread pipe" technology. It equipped with  famous valve groups, and independently developed high-matching PLC control system to realize muitiple linkages. Over pressure, over temperature, low water level, air ignition alarm interlock. The lock protection function ensure the equipment running 100% safety.

  • Most Importantly, WNS fire tube boiler has unique advantages that it could powered by biomass burner, wood chip burner, pellet burner. Customer is easy to replace the burner type according to the local fuel prices.

  • wns gas oil dual fuel fired boiler



Spirally Corrugated Furnace & Wet Back Structure

1. Bigger corrugated furnace design, increased 10% heating area and avoid damaged by heat expansion; 2. Wet back stucture reduce the back tube sheet temperature and protect it from cracking


3-Pass Spiral Fire Tubes (smoke tube) Technology

Use the advanced technology which is our patent to design the spiral tubes, to enhance the boiler thermal power 10-15% higher than normal, and avoid the spiral tube from ash deposition and wearing


Easy Operation, lntelligent Monitoring, 100% Safe

100% safe and easy to operate. Abnormalities such as steam temperature, water level, differential pressure, smoke temperature and flow can be interlocked and alarmed.


Economizer/Condensor Design, Energy Saving

Recycle exhausted smoke to heat feed water, reduce exhaust smoke temperature below 95 ℃, increase feed water temp then save fuel cost at least 6% per hour
