Claims

[Scope of utility model registration request]

Both the upper header 1 and the lower header 2 are formed in an annular shape, the upper and lower headers are connected by a large number of inner water pipes 3, and these inner water pipes are arranged as an annular water pipe wall with a slight gap A, Furthermore, the upper and lower headers are connected by a large number of outer water pipes 4, and the pitch angle A of the inner water pipes and the pitch angle B of the outer water pipes are the same, but the pitch angles are shifted from each other. While forming a slight gap, the outer wall 5 closely surrounds the outside of the outer water pipe 4,
A burner 6 is provided inside either the upper header 1 or the lower header 2 to form a space surrounded by the inner water pipe wall in the combustion chamber 7, and each of the inner water pipes 3 is provided with an adjacent outer water pipe. The outer wall 5 extends vertically over almost its entire length on the outer surface of the side, and maintains a slight gap between it and the outer surface of the adjacent outer water pipe.
By fixing two plate-shaped fins 8 in contact with each other, a vertical combustion gas flow path 9 is created within the plate-shaped fins 8.
and a communication path that communicates the vertical combustion gas flow path 9 with a gap flow path 10 formed between the outer water pipe 4, the plate-like fin 8, and the outer wall 5 at the burner side end of the plate-like fin 8. A multi-tube once-through boiler characterized by forming 11.
