📘 Product Description
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 (1st pass). High temperature smoke is collected in reversal chamber and enters the 2nd pass (grooved tubes bundle area). After convection, air temperature falls and goes to the front smoke box for the 3rd pass (smooth tubes bundle area), then exhausts to the atmosphere via the chimney.
