Introduction:  

YLL(YGL) series of organic heat-medium boiler is the vertical assembly forced circulation coal-fired boiler.The compact 

heating area comprises of inner and outer closely-aligned round coils.Inner coils are the radiation heating area and outer 

coils serve the convection heating area with external surface of inner coil. Boiler is structured into the body drum on the 

combustion chamber,which shall be assembled on site.Fuel burns thoroughly in the combustion chamber.Most heat is absorbed by 

the radiation heating area and residue hot fume flows in the convection in the air preheater. Finally it exhausts outside 

through chimney via the dust collector and draught fan.

Simple installation and short installation period, just need to combine the upper body and lower combustion chamber.
