WNS hot water boiler is a kind of horizontal type internal combustion three return boiler with wet back structure, the combustion chamber adopts lower-position arranged corrugated furnace,which can increase the radiation heating surface and enhance the boiler efficiency to maximum degree.Oil/gas fired boiler is equipped with superior performance burner,which can realize automatic combustion proportion adjustment, automatic feed water regulation, automatic program start-up and shut-down, in addition,it has automatic protection functions of high/low water level,ultra low water level, high pressure, automatic flameout,etc.

Production advantage:

• Three return structure and large volume combustion chamber design make sure the combustion more sufficient.

• Advanced corrugated furnace structure increases the heat transfer area and satisfies free expansion of the furnace after being heated.

• Large diameter corrugated furnace provides large combustion space,sufficient fuel combustion,effective absorption of heat and thermal expansion and large radiation heating surface.

• Adopt wet-back structure with butt weld,which provides high reliability and low maintenance costs.

• Explosion-proof door offers higher safety guarantee and easier observation of combustion status.

• Protective functions of over temperature, over pressure, water shortages, leak detection, flame out to ensure safe and reliable operation of boiler.

• Equipped with imported burner with superior self-control performance,which can achieve fully automatic operation.
