構造。[Claims for Utility Model Registration] (1) 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 water pipes, and these water pipes are spaced apart in the radial direction. are arranged as two concentric annular water tube rows 3 and 4, and a combustion chamber 7 is formed within the inner annular water tube row 3,
The inner and outer water tube rows 3 and 4 form an annular combustion gas passage 5, and the inner water tube row 3 is provided with an opening 9 to the outer annular combustion gas passage 5. A multi-tube is provided with an opening 10 communicating with a flue 11 provided in the boiler outer wall 8, and has flat plate-shaped fins 12 arranged in multiple stages in the tube axis direction on the outer surface of the water tube facing the combustion gas passage 5. In a once-through boiler,
The flat fin 12 is provided so as to form an inclined surface with respect to the flow of combustion gas in such a manner that it gradually moves away from the central extension line (reference level) of the flue as it goes downstream of the combustion gas. Heat transfer surface structure of a multi-tubular once-through boiler. (2) An appropriate number of slits 1 are formed so that the flat fins substantially intersect with the flow direction of the combustion gas.
3. A heat transfer structure for a multi-tubular once-through boiler as set forth in claim 1 of the utility model registration claim.
