Yongxing pellet fired boiler is a horizontal three-return structure.
Workflow is as follows: Coal fuel falls from the coal hopper to the grate and enters the furnace to start burning.
The flue gas after combustion enters the rear of the boiler through the rear arch (first return), then enters the front of the boiler through the convection flue (second return), and finally enters the rear smoke box through the threaded pipe (third return).
The burned exhaust gas enters the economizer, the dust collector, and the induced draft fan, and is discharged to the atmosphere through the chimney.
