Fire tube condensing gas / oil boiler introduction

  WNS Series of horizontal internal combustion boiler is the boiler hull type horizontal tri-backhauling internal combustion boiler designed by our technical professionals according to the advancedtechnology from home and abroad combined with practical experiences. The boiler is fully automatic, the fuel after atomization by the burner forms the flame filling the whole waveform furnace and via furnace wall to transfer the radiant heat, this is the first backhaulting. The high temperature smog yields from combustion is concentrated inback combustion chamber and turns to the second backhauling, i.e., whole pope bundle area; After heat exchange by convection, the smog temperature gradually lowers and goes into the front smog chest, and there turning to the third backhauling i.e., bare pipe bundle area, and then passes through rear smog chest to chimney, and funally exhausts to the atmosphere

  This series of products are safe, reliable, efficient, energy-saving environmental protection, main.

Fire tube condensing gas / oil boiler advantage
Boiler manufacturing process
  • key processing technology like material preparation of steel tubes, circling, drilling of tube plate, etc are all adpot advanced CNC machining process to decrease the assemble stress and extend the boiler working life
  • The front and rear somke chamber panel adopts CNC plasma cutting machine to cut orderly and beautifully
Boiler welding process
  • The boiler vertical and circular seam adopts advanced unionmelt welding process to ensure the welding quality. All the vertical and circular seams will be done 100% radiographic Inspection
  • The weld of smoke tube and tube plate will be pre-expanded first to remove the gap between tube and tube plate. And then adopt argon arc automatic welding process. This may relief stress effeciently and extend the boiler woking life.
Furnace insulation
  • Adopt high-class aluminium silicate fibre. Use refractory mortar to keep the furnace temperature under 45℃ and control heat loss effeciently
  • Font and rear smoke chambers are filled with multilayers of aluminium silicate fibre and be insulated by high temperature refractory mortar.This may increase thermal resistance and decrease heat loss effeciently to improve heat efficienct.
