WNS type automatic horizontal steam boiler is a horizontal quick - mounted internal - burning three - return - trip fire tube boiler.The bifurcated flue gas is used to wash the second and third return flue gas pipes successively, and then the flue gas chamber is discharged into the atmosphere through the chimney.The boiler is fitted with movable front and rear smoke box covers to facilitate boiler maintenance.

WNS series is a classical shell type boiler, with classical design: firetube+ wetback+ 3pass. Its average thermal efficiency >95%, design working life span more than 15 years. Equipped with well-known auxiliary parts, such as BALTUR/RIELLO- burner, DANFOSS- pressure controler, SIEMENS- PLC cabinet, LEO- multistage pump, etc. to ensure the steady performance.

Unique technical expression:

Unique technical design	Function
1.Spirally corrugated tube	it can strengthen heating transfer,lessen fire tube and the shell size can be narrowed
2.Wet back smoke chamber	reduce high temperature of tube plate
3.Flat tube plate&tilted tension brace	enlarge tube plate area,increase the strength of tube plate
4.European style steam and water separator	to separate steam and water effectively
5.Anti-explosion door	guarantee boiler safety
6.Double deck aluminum silicate heat preservation	reduce heat loss,increase heat efficiency
7.Fast hardening casting material of front and rear smoke box	high temperature resistance,high coagulability,long service cycle
8.Double-deck asbestos heat preservation	enhance air-tightness,prevent smoke leakage
9.Integrated junction box design	connect wire standard
10.Corrugated furnace	enhance the boiler heat surface
11.Independent front and rear smoke box	form independent space to achieve smoke transfer or accumulation
12.Two sides bottom blow-down	achieve bottom blow-down of the boiler
13.Surface blow-down	let boiler surface blow-down
14.Platform ladder	offer the boiler maintenance platform

FAQ:

1. What are the available fuel for the oil gas fired boiler?

Oil gas fired boiler could burn both liquid fuel and gaseous fuel. The liquid fuel could be heavy oil, light oil, diesel, furnace oil, bunker oil, LPG (liquefied petroleum gas), etc. The gaseous fuel could be natural gas, city gas, bio-gas, etc.

2. Whether the boiler can burn dual fuel or multi-fuel?

boiler have oil burner, gas burner, and oil&gas dual fuel burner, we can offer the specific burner based on customers’ requirement.

3. What is the thickness of combustion chamber?

the thickness of corrugated furnace is different based on working pressure and furnace diameter, generally, the thickness is between 10~18mm, large combustion space, and combustion sufficient.

4. What is the inlet pressure of gas burner?

The inlet gas pressure is different for different capacity boiler, for example, the pressure for 2 ton steam capacity boiler is about 8~10KPa, while for 4 ton steam capacity boiler is about 18~20KPa.

5.The brand of burner?

The brands of burner are Italy Baltur, Rellio, Elco, etc.
