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.
Performance advantage
1. Boiler design
Horizontal internal combustion three return journey full wet back design, 100% corrugated furnace, with good thermal retrability, water cooled retrorse chamber, retrorse chamber and back tubeplate butt joint, lowest stress, more reliable quality.
2, large diameter corrugated furnace
The boiler combustion chamber is composed of a large diameter full ripple furnace with large combustion space, complete fuel combustion, effective heat absorption and thermal expansion, and large radiation heating surface.
3. Sufficient heat
The heating area of the boiler is designed to be more than 25 square meters/ton, fully absorbing effective heat, low smoke exhaust temperature, small heat loss, ensuring sufficient output and high efficiency.
4. Steam quality
Pot shell diameter, large water capacity, strong adaptability to load changes, stable output, steam space volume, soda interface and steam outlet net distance is high, low steam humidity.
5. Multi-functional safety and explosion protection device
The back plate of the boiler is equipped with the explosion-proof device which is connected with the furnace to prevent the high energy of the discharge moment when the fuel is violently deflated in the furnace, and it can automatically reset. Meanwhile, it has the function of the fire-viewing mirror and the maintenance channel. It makes use of the adjustment of the burning flame in operation, and makes the furnace inspection and maintenance convenient.
