Title:

HEAT EXCHANGER, BOILER, AND SETTING METHOD FOR HEAT EXCHANGER

Document Type and Number:

Japanese Patent JP2019128107

Kind Code:

A

Abstract:

To provide a heat exchanger capable of reducing a heat absorption amount from combustion gas without requiring a lot of manhours.SOLUTION: The present invention provides an economizer 70 including: a plurality of cylindrical heat transfer tubes 71a-71d extending along a crossing direction crossing a flowing direction of combustion gas and disposed at predetermined disposition intervals P along the flowing direction, where the combustion gas and fluid flowing in the heat transfer tubes perform heat exchange; and a swirl preventing section 75 disposed in contact with a downstream side outer circumferential surface 71Aa-71Ad in the flowing direction of each of the heat transfer tubes 71a-71d and configured to prevent a swirl of the combustion gas from occurring near the downstream side outer circumferential surface 71Aa-71Ad.SELECTED DRAWING: Figure 3
