Claims

[Scope of utility model registration request]

Both the upper header 1 and the lower header 2 are formed in an annular shape, and the upper and lower headers 1 and 2 are connected by a number of vertical water pipes 3, and these water pipes 3 are arranged as an annular wood pipe wall with a slight gap. The boiler outer wall 4 is installed with a space on the outside of the wood pipe wall.
An annular combustion gas passage 5 is formed between the water tube wall and the boiler outer wall 4, a combustion device 6 is provided inside the lower header 2, and the inside is horizontally positioned above the water tube wall. A partition wall 7 is provided, and the space below the partition wall 7 is formed into a combustion chamber 8, and the space above it is formed into a flue 9, and a water pipe 3 is formed.
A heat transfer promoting plate having a substantially V-shaped cross section is installed in the valley of the portion of the finned water tube 3 facing the boiler outer wall 4 by attaching a fin 11 that is circumferentially or spirally formed and substantially annular to the fin 11 . 12, these heat transfer promoting plates are arranged so as to have a slight gap between them and the finned water pipe 3,
A multi-tube once-through boiler characterized by forming a forced gas flow path between the upper and lower fins.
