WNS series steam boiler is a kind of horizontal,  gas & oil fired, 3-pass, wetback type, fire tute type , forced circulation and low pressure steam boiler. The fuel could be LPG gas, natural gas, diesel, waste oil, heavy oil...etc. This WNS series steam boiler is an enegy saving , environment friendly, high efficiency and high safety boiler for chemical, oil, textile, petrochemical, synthetic chemical fiber, wood, food, plastics, rubber, building material industry..etc. 

General features of WNS series boiler:

1.    horizontal , gas & oil fired , fire tube, industrial and low pressure;

2.    wetback and three-backhaulstructure design;

3.    With high efficiency economizer, the thermal efficiency can reach more than 90%.

4.    The spring-loaded type explosion door ensures the boiler safety

5.    The removable smoke boxfacilitates the maintenance

6.    Internal micro positive pressure combustionreduces the low temperature corrosion.

7.    Equipped with protection devicesfor overheating, overpressure, lacking water, leak detection, flameout, etc. This ensures the boiler to operate safely and efficiently.

The product advantage:

1.    Subulate furnace and corrugated furnace combination

Function: (1) Make the structure more compact; (2) improve the thermal efficiency; (3) relieve the expansion and contraction

2.    Smooth tube and spirally corrugated tube combination

The smooth tube

Function: Prevent the exhaust from condensing inside the boiler to prolong its service life ;

The spirally corrugated tube

Function: (1) relieve the expansion and contraction; (2) Heat transfer enhancement;; (3) clean groove by itself.

3.    The furnace sits in line with the combustion

Function: (1) Make the structure more compact; (2) prolong its service life;

Mark:

The combination of our gas fired boiler, imported burner and economizer are the perfect match, which is high-efficient, environment-friendly and energy-saving.

The measures of quality assurance as follow:

1. Strength calculation report with applied materials information;

2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod;

3. 100% X-ray inspection report (welding seam): to ensure the quality of the entire boiler;

4. Hydraulic test report: ensure the standard working pressure and safety;
