Provided is a combustion control device (50) that is equipped to a gas turbine that comprises a compressor (2), a combustor (3), a turbine (4), extraction piping (12) that returns extracted air to the inlet of an intake apparatus (7), and an extraction valve (22) that regulates the extracted amount of extracted air. The combustion control device (50) comprises: a combustion distribution setting unit (70) that, on the basis of input data, sets a turbine inlet temperature or a control variable that corresponds to turbine inlet temperature, and sets a fuel distribution ratio on the basis of the turbine inlet temperature or the control variable that corresponds to turbine inlet temperature; and a fuel-valve opening angle setting unit (81) that sets the valve opening angle of a fuel regulation valve. The fuel distribution setting unit (70) includes a correction means that modifies the fuel distribution ratio.
