ことを特徴とする、多管式貫流ボイラ。 It has a large number of inner row heating tubes and a large number of outer row heating tubes that are arranged upright around a combustion chamber and arranged in an annular shape, and the combustion gas coming out of the combustion chamber is connected to the inner row heating tubes. The gas passage of the contact bath part flows along the annular shape between the outer row heating tubes, and the gas inlet of the combustion gas passage is provided toward the inner row heating tube, and In a multi-tube once-through boiler with a double-tube can structure, in which a gas outlet portion of the combustion gas passage is provided on the side of the outer row heating tube opposite to the gas inlet portion, the combustion gas in the combustion gas passage is The annular center position of the inner row heating tube is set so that the combustion gas passage near the gas inlet is larger than the combustion gas passage near the gas outlet so that the flow velocity of the inner heating tube is approximately constant. A multi-tubular once-through boiler, characterized in that the row heating tubes are eccentrically located toward the gas outlet section with respect to the annular center position of the row heating tubes.
