Product Description
This gas boiler consists of threaded firetubes, corrugated furnace, boiler shell, insulation lay, stainless steel coat, instrument valves and an integral burner.
Introduction
WNS series horizontal internal combustion boiler is classic 3-pass wetback oil/gas fired boiler. After fuel is atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, called 1st pass; the high temperature flue gasses are collected in reversal chamber and then enter 2nd pass, which is grooved tube bundle area through heat convection, air temperature gradually falls and flows to front smoke box and enter 3rd pass, which is done in the smooth tube bundle area, and then through back smoke box lead to chimney and exhausted to the atmosphere.
Digitized manufacture
Easy operation and maintenance
Long service life
The way to weld Smoke tube and tube sheet is to first expand to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boiler service life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint are test by radiographic inspection.
Fin tube uses ND steel or stainless-steel material to avoid corrosion in the low temperature .
Inspection stops are set up to guarantee the sequence of expanding and welding to avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45ºC and reduce heat lost.
- Sufficient steam storage room and heating area to generate high quality steam and high thermal power.
Condenser is added to recycle the waste heat of the exhausted smoke to increase feeding water's temperature and reduce flue gas emission temperature and increase the thermal efficiency over 95% and save operating cost.
1.1 Long working life3-pass and wet-back are designed to avoid the damage of back tube sheet from the high temperature smoke.
1.2 Compact desegnThreaded 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 economizerIt 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 emissionsLowering 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 systemWe 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
