YYW/YYL Liquid Phase Furnace Oil Burning

  YYL(YYW)series of organic heat transfer oil boiler is packaged forced circulation oil/gas fired boiler. This series of 

boiler body has a compact heating surface, consisting of inner,middle and outer(or inner and outer)closely aligned round 

coils. Inner coils are radiation heating area and middle and outer coils serve the convection heating area with external 

surface of inner coil. Fuel burns and generates heat in the combustion chamber of inner coils. Most heat is absorbed by the 

radiation heating area and residue hot fume blows in the convection heating area for heat exchange. Finally low-temperature 

fume exhausts outside through the chimney via the fume outlet of boiler.
