The combustion chamber interior has a control means that performs control so as to form a premixed ammonia gas such that the ammonia concentration at the inner side wall surface of the combustion chamber is higher than in the center of the combustion chamber, and the control means makes adjustments so that the excess air ratio is lower than the excess air ratio during operation performed using only fuel oil.
