Diesel Condensing Hot Water Boiler

1.Long working life 

3-pass and wet-back are designed to avoid the damage of back tube sheet from the high temperature smoke.

2.Compact desegn

Threaded firetube and corrugated furnace are used to increase the heating area. That allows over 30% of the energy to be absorbed in the furnace. This means a shorter boiler overall. Definitely, it can save your boiler room construction costs.

3.Ease of maintenance

Everything is up front,adjustable and accessible.

4.New type economizer

It is made by finned steel tubes. The material is ND steel (09CrCuSb), which is corrosion-resistant at low temperature. It is smaller but the heat exchanging area is bigger than normal. By calculation, It can save around 5% fuel.

5.Low emissions

Lowering emissions in the ZOZEN-WNS series of boiler involves two key factors: 

(1) advanced burner solution; 

(2) the proper sizing of furnace to minimize nitrogen oxides and other contaminants from forming during the combustion process.
