ーにおける二列水管式缶体の改良。 The upper header 1 and the lower header 2 are connected by two concentric water tube rows 3 and 4, and the combustion chamber 6 is located inside the inner water tube row 3, and the inner water tube row 3 and the outer water tube In a multi-tube once-through boiler, an annular first combustion gas passage 8 is provided between the outer water tube row 4 and the boiler outer wall 5 on the outside of the outer water tube row 4. The first combustion gas passage 8 and the second combustion gas passage 9 are connected by forming an annular second combustion gas passage 9 between them, and by providing an opening 13 extending over the entire length of the tubes in the outer water tube row 4. Connect the inner water tube row 3 with a slight gap 33
It consists of a water tube row section 31 with a water tube row section 31 and a water tube row section 32 with no gaps, and a fin 10 is attached to each water pipe of the former water tube row section 31 over its entire length.
These fins 10 are arranged with an extremely small gap 34 between adjacent water pipe circumferential surfaces, while openings 1 of the latter water pipe row portion 32 with no gap are provided.
3. An improvement of a double-row water tube type body in a multi-tube once-through boiler, characterized in that the body is located on the side facing the water tube and is composed of water tubes without fins.
