The present invention relates to an exhaust heat collecting device comprising: a body receiving an intake of an exhaust gas exhausted from a gas turbine; a heating tube installed in the body, collecting heat from the exhaust gas; a dispersing unit installed in an interval from the heating tube, reducing a speed of the exhaust gas; a distance adjusting unit moving the dispersing unit; and a measuring unit acquiring speed information by measuring the speed of the exhaust gas received in the body. The distance adjusting unit is characterized by moving the dispersing unit to adjust a distance between the heating tube and the dispersing unit in accordance to the speed information measured by the measuring unit. The present invention improves durability of the heating tube by preventing damage to the heating tube installed to absorb heat from the exhaust gas, thus reducing expenses for maintenance. |
