PURPOSE: A pellet boiler and a burner structure thereof are provided to prevent unburned pellets from being fallen because an upwardly inclined stopping sill is formed on an end portion of an ash tray so that the combustion efficiency of the pellets is improved. CONSTITUTION: A burner(140) for a pellet boiler comprises an air chamber(141), a blower(142), a pellet supplying guide(144), a heater(146), and an ash tray(147). A fuel supply unit supplying pellets is attached on the upper part of the air chamber. The blower supplies air required for the combustion of the pellets. The pellet supplying guide is inclined downward in the inside of the air chamber. The pellet supplying guide provides a moving path of the pallets supplied from the fuel supplying unit. The heater is installed under a lower end of the pellet supplying guide and ignites the pellets supplied along the pellet supplying guide. The ash tray has a multi-stage downward inclined structure. The air supplied from the blower is discharged to an upper side through a plurality of air holes of the ash tray. |
