1. A method comprising:
passing air through an air flow path of a combustion device, wherein the air flow path communicates with an opening of a liner, the opening is at an end of the liner, the liner defines a combustion chamber, and the air flow path is a path for supplying the air to the combustion chamber;
flowing ammonia through a space defined by and inside an ammonia supply pipe of the combustion device, wherein the ammonia supply pipe is inserted through the opening of the liner, and the ammonia supply pipe is a pipe for supplying the ammonia to the combustion chamber; and
flowing starting fuel through a space defined by and between the ammonia supply pipe and a starting fuel supply pipe of the combustion device, wherein the starting fuel supply pipe is disposed between the ammonia supply pipe and the air flow path, wherein the starting fuel supply pipe covers a curved surface of the ammonia supply pipe, and the starting fuel supply pipe is a pipe for supplying the starting fuel to the combustion chamber,
wherein the ammonia supply pipe is inserted in the starting fuel supply pipe.
 
2. A combustion device comprising:
a liner including an opening at an end, wherein the liner defines a combustion chamber;
an air flow path communicating with the opening of the liner, wherein air passes through the air flow path, wherein the air flow path is a path for supplying the air to the combustion chamber;
the air that passes through the air flow path, wherein the air is within the air flow path;
an ammonia supply pipe inserted through the opening of the liner, wherein the ammonia supply pipe defines a space through which ammonia flows inside the ammonia supply pipe, wherein the ammonia supply pipe is a pipe for supplying the ammonia to the combustion chamber;
the ammonia that flows through the space defined by the ammonia supply pipe, wherein the ammonia is within the ammonia supply pipe;
a starting fuel supply pipe disposed between the ammonia supply pipe and the air flow path, wherein the starting fuel supply pipe covers a curved surface of the ammonia supply pipe, wherein the starting fuel supply pipe defines a space through which starting fuel flows between the ammonia supply pipe and the starting fuel supply pipe, wherein the starting fuel supply pipe is a pipe for supplying the starting fuel to the combustion chamber; and
the starting fuel that flows through the space defined by and between the ammonia supply pipe and the starting fuel supply pipe, wherein the starting fuel is within the starting fuel supply pipe,
wherein the ammonia supply pipe is inserted in the starting fuel supply pipe.
