1.Brief Introduction:

WNS series oil and gas steam boiler adopts shell type full wet back type fire tube structure. the structure adopts three return journeys, in which the oil or gas is well atomized by the burner and fully mixed with the air, and is completely burned in the corrugated furnace bile, and then turns from the rear smoke chamber into the return smoke pipe, turns to the front smoke box into the return smoke pipe, enters the back smoke box, and is discharged by the chimney.The size of the furnace liner we choose is large, which provides conditions for the full combustion of fuel, so this packaged steam boiler can burn heavy oil, light oil, natural gas and city gas. In addition, our company adopts threaded smoke pipe in the design, and the relative flow rate can control low smoke resistance, low power consumption and large load regulation ratio under the guarantee of sufficient heat transfer.

3.Performance features:

1. the overall structure is reasonable and compact, belonging to the packaged steam boiler which meets the delivery conditions of quick installation.this steam boiler is composed of three parts when it leaves the factory;the main steam boiler, chimney and piping system, in which the main engine and chimney parts have been manufactured in the factory, and the piping valves and instruments supporting the main boiler have been installed randomly, and then transported to the site to assemble the main engine and chimney.On the spot connect the air source, power supply and water pipeline to start the test.Greatly shorten the installation cycle, and can guarantee the quality of products.

2. Advanced design performance.the main boiler is of integral structure, the burner is assembled on the cover of the front smoke box, and the main body is arranged with heating surface and combustor.with reasonable structure, compact, low steel consumption, furnace with offset waveform furnace, thermal insulation layer choose new lightweight heat insulation material, outer packing USES color sheet, appearance packaging for cuboid, the boiler performance, weight, structure size and appearance modelling and compared with the capacity of the domestic product has obvious advancement and the look and feel.The boiler feed water equipment is arranged on the boiler base on the right side of the boiler so that it can be integrated with the main engine without having to make another foundation.

3. Our packaged steam boiler is simple water circulation, reasonable structure of pressurized parts, safe operation under the condition of ensuring water quality.

4. Complete auxiliary equipment and advanced comprehensive technical performance.
