YYL(YYW)organic heat-medium boiler is snap-type forced circulation oil gas-fired boiler.The compact heating area comprises of inner,minddle and outer or inner and outer closely-aligned round coils.Inner coils are the radiation heating area and middle and outer coils serve the convection heating area with external surface of inner coil.Fuel fires and generates the heat in the conbection chamber of inner coils.Most heat is absorbed by the radiation heating area and residue hot fume flows in the convection heating area for heat exchange.Finally low-temperature fume exhausts outside with chimney via the fume outlet of boiler.
Extremely flecible and simple installation.Just place the boiler on the foundation.
Heating area is the closely-aligned round coils.Heating area is arranged sufficiently to reduce the surface heat load of pipe and handle the heat transfer oil safely.
Size of hearth matches the combustion flame.Use the barotropic combustion to increase the radiation heating efficiency.
Compact boiler saves the space of boiler room greatly.
Air preheater is mounted at the tail of large boiler to improve the efficency.
