Product Detail:

This is a gas/oil-fired steam & hot water boiler. My main structure is the below:

 

Boiler shell

Corrugated furnaceThreaded firetube

Intergrated burner

Insulation materialStainless steel coat

Instrument valves

Double insulation jobDebugging job

 

Boiler features


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 acid-resistant and 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.

 

6.High Efficiency

Attaining high fuel to steam/water efficiency in a boiler today requires a highly engineered package from a single source who is providing integrated burner, controls and the heat exchanging vessel. Zozen WNS series of boilers is the premier package in the domestic Industry guaranteeing the highest efficiencies.

 

7.Safety control system

We design the safety interlock system with multiple protection and alarm functions

- Protection program of automatic ignition

- Locking and protection program of operation

- Protection program of extinction

- Protection program of completion

- Protection program of water pumps (pressure loss)

- Protection program of ignition failure

- Protection program of combustion engine malfunction

- Protection program of combustion engine flameout

- Sound-light alarm of high pressure 

- Sound-light alarm of high limit water level

- Sound-light alarm of low limit water level 

- Sound-light alarm of super-high temperature of hot water
