WNS series gas/oil fired industrial steam boiler use international most mature three-pass all wet back structure,safety and reliable .Use waveform furnace ,strengthens the disturbance of the smoke and increases the radiation heat transfer area ;increases the stiffness of the furnace and effectively reduces the thermal stress of the furnace;enhance heat transfer and promote the combustion of fuel in the furnace.The heating surface is arranged symmetrically with solid structural strength and reasonable water circulation .Boiler up part inside has full water capacity ,big steam space and good quality steam .During procession ,the water level fluctuation is small .Big distance between two ends boiler ,big diameter of tubes ,all of these ensure good natural circulation . Steam boiler with very small heat loss  because of unique furnace and flue gas thermal surface design .
WNS type oil and gas boiler is steam boiler developed in cooperation with German technology. Its technical indexes all reach the world's advanced level.The type boiler really did clean combustion, emissions, no pollution, convenient operation, the output is enough, the ontology of pot shell all wet back downstream three return fireworks tube structure, indoor micro positive pressure combustion flame in the combustion, burning full, furnace heat load is low, the SOX. The harmful substances less NOX emissions, corrugated furnace and threaded pipe structure, which can not only improve the strength and strengthening heat transfer effect, and meet the requirements of parts heat expansion at the same time.The front and rear smoke boxes are connected by hinges, which can be opened easily and repaired quickly.
Performance advantages:
Low cost: The implementation of the West-east gas transmission makes the price of natural gas lower and fuel cost lower accordingly;This type of boiler has high combustion efficiency, fuel saving and low fuel investment cost.Full bevel butt-weld, long safety life and low maintenance cost.
High efficiency: The tail part is equipped with flue gas condensation recovery device, which can effectively control the exhaust temperature, and the boiler has high thermal efficiency;Adopt automatic burner, feed water adopt continuous electric adjustment, combustion efficiency is high.
Safe and stable: Designed over temperature, over pressure, water shortage, leak detection, flameout and other protection functions, boiler operation is safe and reliable.
Space saving: adopt quick installation structure, the whole boiler is designed on the base with strong steel, easy to install and transport, saving the space occupied by the boiler room.

Scope of application:
1. Industrial user : pharmaceutical, paper, tobacco , printing and dyeing , garment and other industries ;
2. Civil: catering , laundry, ( hospital ) disinfection, sauna , etc ;
3. By steam - water heat exchanger for heating systems ( air conditioning , radiators , floor heating , etc. ) of hot water ;
4. Provide power for the lithium bromide absorption chiller (pressure P = 0.6-0.8Mpa)
