Introduction
WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
- Smoke Box
- Adopting hinged structure with good sealing effect
- Easy maintenance, inspection, and cleaning
- Corrugated Furnace
- Strong flue gas disturbance and good heat transfer effect
- Enhancement of furnace strength and elasticity
- Economizer and Condenser
- Improve the thermal efficiency to more than 95%
- Finned tubes for enhanced heat transfer efficiency
- Threaded Smoke Tube
- Extending flue gas residence time for enhanced heat transfer
- High-efficiency heat transfer element, 1.4 times more efficient than regular smoke tubes
