The fire holes are communicated with the containing cavity and used for spraying out fuel gas. The first connecting structures and the edge of the combustor are arranged at intervals, and at the connecting position of the first body and the second body, the first connecting structures block communication of the fire holes and the containing cavity, or the first connecting structures are located at the edge of the combustor, and the first connecting structures are located between every two adjacent fire holes. The first connecting structure is arranged close to the position of the fire hole, so that the situation that the combustor deforms after being used for a long time is reduced, and it is guaranteed that the combustor can stably and safely operate.
