PURPOSE: A fire-tube boiler including a rotary roaster is provided to promote the efficiency of a boiler by processing foreign materials using a reprocessing unit. CONSTITUTION: Fuel is automatically ignited by an electric heater(22). The generated heat and gas are supplied to a first combustion chamber(30). The heat and the gas are ignited in a second combustor(40), a third combustor(50), and a fourth combustor(60). A waste gas is discharged through an exhaust pipe(61). The heat and the gas heats a heat exchange pipe(42). Foreign substances of the ignition process is gathered in the reprocessing unit(51) of the third combustor. Foreign substances generated from an ignition unit(20) is gathered at the bottom of the reprocessing unit(24). |
