PROBLEM TO BE SOLVED: To prevent unburnt carbon from adhering to an inner surface of a pre-evaporation pre-mixture flow passage body by raising and keeping temperature of the pre-evaporating pre-mixture flow passage body to temperature at which carbon is produced or higher. SOLUTION: A gas turbine combustion device provided with the pre-evaporation pre-mixture flow passage body 15 forming a pre-evaporation pre-mixture flow passage for mixing evaporating liquid fuel and air for combustion is provided with a heating device 21 for air for combustion provided in a passage of air for combustion defined by an outer tube 4 and an inner tube 7 of a combustor, a liquid fuel supply equipment 19 supplying fuel to the heating device 21, a flow rate adjusting device 27 detecting temperature of air for combustion supplied to the heating device 21, a first temperature detector 30 detecting temperature of air for combustion supplied to the heating device 21, a second temperature detector 29 detecting temperature of the pre-evaporation pre-mixture flow passage body 15 and a control device 31 controlling the flow rate adjusting valve 27 based on detection signal from the first and the second temperature detectors.
