WNS automatic oil(gas)-fired steam boiler is the horizontal, three returns, fire-tube boiler, mainly consisted of shell, undee furnace, diversion smoke chamber, fire tubes ,etc. The fuel can be light oil, heavy oil, natural gas, liquefied gas, city coal gas and so on.
1. Adopt the structure of wet-back and undee furnace, effectively reduce the boiler’s thermal stress and improve the safety and service life.
2. Heating surfaces are symmetrical layout and the forces and inflation is more reasonable;
3.Reasonable decoration of heating surfaces guarantee a good heating water circulation and heat transfer. The heat transfer effect can achieve the best condition, thus improve the boiler thermal efficiency .
