WNS gas (oil) steam boiler

Conden gas-steam boiler is a wok shell type with three backflow downstream pyrotechnical tube structure.The flame burns under micro-positive pressure in the corrugated furnace with high combustion thermal efficiency. The corrugator can be fully extended according to the temperature and the heat transfer area can be increased at the same time. The second return journey adopts the thereadded pipe structure,which improves the heat absorption intensity of the boiler effectively reduces the smoke exhaust temperature,saves energy and reduces consumption, and is economical to use, The third return journey adopts the ligth smoke tube,which can effectively reduce the smoke resistance of the boiler,improve the combustion efficiency and reduce the operating noise on the burner ,There is enough steam space in the upper part of the boiler,coupled with the use of advanced and reasonable steam separation device, the steam quality is quite stable.

WNS series boiler are widely used in textile industry,chemical,oil,petrochemical, printing and dyeing,plastic, fiber,carbon, papermaking,wood, food, brewing, heating and air-conditioning industries.lt is characterized by fast steam output,stable operation, convenient installation and use, low operating cost and long service life.
Characteristic description
1. lt has high/low water level alarm and low water level interlock protection function,steam pressure overpressure alarm and overpressure interlock protection function. At the same time, the drum is equipped with a verified safety valve to improve safety.
2. A waste heat recovery device is installed at the end of the boiler to further reduce flue gas temperature, realize the release of sensible heat of flue gas and latent heat in water vapor, and further improve boiler efficiency.
3. Compact structure,convenient installation and transportation. The front/rear smoke doors are symmetrically movable hinged, which is convenient for opening, maintenance and cleaning. The rear smoke box has two doors, a fire hole and an inspection hole for easy inspection and the climbing ladder is convenient for installing auxiliary machines.

Advanced technology utilization

1．Add water separation partition in the second and third return of WNS boiler

The flue gas temperature of the outlet of the third pass can be decreased from 217℃ to 196℃ with the water separator.

2. Smoke chamber door adopts three layers of heat preservation, double sealing structure, which can ensure good heat preservation and sealing effect.

The surface temperature of the smoke chamber is controlled below 40℃.
