Coal-Fired or Biamass-Fired Chain Grate Thermal Oil Boiler(Ylw

RUNLI YLW series organic heat carrier boiler is the packaged forced circulation chain glare boiler.
Front section of boiler body is the hearth radiation heating area consisting of closely aligned double square coils.
The rear section is the convection flush heating area of S shaped tube bank.
Boiler is structured into the body drum on the combustion chamber, which shall be assembled on site.
Air preheater is mounted at the rear of boiler.
Some heat of combustion hot fume is absorbed by the hearth and residual fume flows in the convection heating area for heat exchange via diversion fume chamber. Heat from the boiler is used to heat the air required for the boiler combustion in the air preheater.
Finally fume exhausts outside with chimney vie the dust collator and draught fan.


Featrures of Coal/Biomass Fired Chain Grate Thermal Oil Boiler 

1. Simple installation and shod installation period Just combine the upper body with lower combustion chamber
2. Hearth consists of double closely aligned coils to ensure the sufficient heating area and reduce heat load of pipe and handle the heat conduction oll safely.
3. Reasonable medium flow Heat conduction oil flows from the lower inlet to the upper outlet 
4.Gas generated during the operation hardly stays in the boiler and can exhaust easily
5. Fume can stay in the hearth long enough for better combustion due to the sound design of furnace arch.
6.Heating area in the diversion fume chamber will avoid the partition being directly flushed from hot fume to effectively prevent the fume shot1 circuit from the falling partition debris
