WNS系列水平ntal型内燃锅炉是典型的三通湿式燃油/燃气锅炉.燃料被燃烧器雾化后，火焰充满了波炉，通过炉壁传递热量，称为第一道；高温烟道气体被收集在反转室，然后进入第二道道，通过热对流进入沟槽管束区，空气温度逐渐下降，流向前烟盒，进入第三道道，进入光滑管束区，再通过后烟盒进入烟囱，排放到大气中。
-
The key processes including material cutting, rolling, drilling are made by advanced CNC machining process to reduce the assembly stress and extend boiler working lifetime.
- The front and back smoke chamber plates are cut by CNC plasma cutting machine with tidy and beautiful look.
-
Fully intelligent operation, with automatic adjustment and protection of burning, water level, temperature and steam pressure. The smoke box door uses the hinge structure for easy inspection, inventory and cleaning.
-
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.
-
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ 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 98% and save operating cost.
