    • The present invention relates to a circulating fluidized bed gasifier equipped with a microwave plasma torch. More specifically, the present invention relates to a circulating fluidized bed gasifier, which immediately generates plasma flame at high temperatures corresponding to several thousand Celsius degrees by a plasma generator, and gasifies fuel while fluidizing the fuel in a reactor by supplying hydrocarbon-based fuel to the generated plasma flame, wherein a reaction chamber of the gasifier is separately composed of a first gasification chamber in which the gasification occurs with heat directly delivered from the plasma flame, and a second gasification chamber in which the gasification occurs with heat indirectly delivered through the first gasification chamber so that gasification is simultaneously conducted by direct and indirect heat transfer from the plasma flame. Also, the first or second gasification chamber is formed with multiple circular projections so that the sectional area repeatedly expands and contracts; the progress speed of the heat generated by the plasma flame is slowed down; the rate of heat transfer to the adjacent chamber or gasification materials and the detention time increase; and the production of synthetic gas by gasification is promoted. As such, the present invention relates to a circulating fluidized bed plasma gasifier with a microwave plasma torch capable of reducing the pre-heating time and promoting the production of synthetic gas.
