PROBLEM TO BE SOLVED: To provide a tornado-type wind mill device which increases the output of a wind mill by improving the speed-increasing effect of the air flow working on blades of the wind mill by the tornado effect. SOLUTION: In the tornado-type wind mill device having a wind force increasing means to increase the wind force on an air passage of the wind mill, the wind force increasing means comprises a combustion chamber provided on a wind mill outlet side of the air passage, and a burner device which ejects the fuel and combustion air into the combustion chamber to burn the fuel, and the flow speed of the air flow working on the wind mill via the air passage by the tornado effect of the combustion gas flow in the combustion chamber is be increased. |
