According to the present invention, a waste heat recovery device comprises: a hot water generating unit which includes an upper housing into which waste heat is transferred, and an economizer of generating hot water by heating cold water coming from the outside using waste heat by being accommodated on an upper housing; a preheating unit which includes a lower housing of being installed in a lower part of the hot water generating unit and allowing waste heat to be transferred inside, and a preheating pipe of being accommodated on the lower housing and preheating hot water supplied from the economizer using waste heat; a dehydration unit installed in a ring shape on a combining part between the hot water generating unit and the preheating unit, and removes moisture included in steam supplied from the preheating pipe by a rotational centrifugal force; an overheating unit installed inside the upper housing or the lower housing in order to overheat steam supplied from the dehydration unit using waste heat; first, second, and third connection pipes which form a passage such that moisture and steam moves by connecting the economizer, the preheating unit, and the overheating unit; and a discharge pipe which discharges steam overheated in the overheating unit to the outside. The waste heat recovery device of the present invention like the above is able to improve efficiency when performing heat exchange with waste heat by securing the expanded length and area of heat exchange as fluid sequentially passes through the economizer, the preheating pipe, and the overheating unit. |
