PURPOSE: A fluidized bed combustor is provided to minimize corrosion caused by combustion gas by directly installing a water pipe capable of collecting heat in an inner wall of a fluidized bed combustion furnace which combusts a refuse derived fuel (RDF) and to collect the heat from the combustion gas in the fluidized bed combustion furnace. CONSTITUTION: A fluidized bed combustor comprises a fluidized bed combustion furnace (10), a first exhaust pipe (20), a cyclone (30), a roof chamber (40), a second exhaust pipe (50), and a heat recovery tower (60). The cyclone is connected to the first exhaust pipe and separates a flow medium from combustion gas. The roof chamber is connected to the cyclone and circulates the separated flow medium to the fluidized bed combustion furnace. The second exhaust pipe is connected to the cyclone and exhausts the separated combustion gas. The heat recovery tower is connected to the second exhaust pipe and collects heat of the combustion gas. A first water pipe (100) collecting the heat inside the fluidized bed combustion furnace is built in an inner wall of the fluidized bed combustion furnace.
