Abstract
An exhaust gas flow regulator and a heat recovery steam generator including the same are provided. The exhaust gas flow regulator includes a plurality of first tubes spaced apart from each other in a vertical direction, a support plate disposed in a direction perpendicular to the extension direction of the first tubes and through which the plurality of first tubes penetrates, and a second tube disposed at one or both ends of the support plate so as to be coupled to the support plate and extending parallel to the first tubes, wherein the second tube is provided with a guide plate disposed to redirect exhaust gases flowing adjacent to the second tube toward the first tube.
Claims17
An exhaust gas flow regulator comprising:
- a plurality of first tubes spaced apart from each other in a vertical direction;
- a support plate disposed perpendicular to an extension direction of the plurality of first tubes and through which the plurality of first tubes penetrates;
- and
- a second tube disposed at one or both ends of the support plate, configured to be coupled to the support plate, and extending parallel to the plurality of first tubes, wherein the second tube is provided with a guide plate configured to redirect exhaust gases flowing around the second tube toward the plurality of first tubes.
A heat recovery steam generator (HRSG) designed to facilitate the recovery of heat from high-temperature combustion exhaust gases discharged from a gas turbine, the HRSG comprising:
- at least one stack;
- a heat transfer tube unit disposed on a lower side of the stack;
- an air duct including a plurality of flow paths having different cross-sectional areas and through which the exhaust gases flow from the gas turbine to the stack;
- and
- an exhaust gas flow regulator disposed in the air duct, the exhaust gas flow regulator comprising:
- a plurality of first tubes spaced apart from each other in a vertical direction;
- a support plate disposed perpendicular to an extension direction of the plurality of first tubes and through which the plurality of first tubes penetrates;
- and
- a second tube disposed at one or both ends of the support plate, configured to be coupled to the support plate, and extending parallel to the plurality of first tubes, wherein the second tube is provided with a guide plate configured to redirect exhaust gases flowing around the second tube toward the plurality of first tubes.
