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.
The installation is very convenient and flexible, just need to place the boiler on the foundation.
