This gas boiler consists of threaded firetubes, corrugated furnace, boiler shell, insulation lay, stainless steel coat, instrument valves and an integral burner.
1.1 Long working life
3-pass and wet-back are designed to avoid the damage of back tube sheet from the high temperature smoke.
1.2 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.
1.3 New type economizer
It is made by finned ND tubes. It is smaller but the heat exchanging area is bigger than normal. By calculation, It can save around 5% fuel.
1.4 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.
1.5 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
