PURPOSE: A waste recovery apparatus for a negative pressure and steam type hot water boiler is provided to be attached to or detached from a hot water boiler, thereby being easily installed in the hot water boiler being installed and operated. CONSTITUTION: A waste recovery apparatus for a negative pressure and steam type hot water boiler includes an exhaust connection unit (110), a waste heat recovery unit (120), and an exhaust unit (130). The exhaust connection unit is connected with the exhaust device (17) of a hot water boiler (10) by a flange to be attached to or detached, and the exhaust gas that is discharged from a hot water boiler is inducted into the exhaust connection unit. The waste heat recovery unit is configured by connecting to the upper portion of the exhaust connection unit, has at least waste heat recovery pipe (121) therein in a horizontal direction, and recovers the waste heat through the heat exchange between the high temperature exhaust gas induced through the exhaust connection unit and the fluid moving in the waste heat recovery pipe. The exhaust gas discharges, to the outside, the low temperature exhaust gas which is heat-exchanged in the waste heat recovery unit. |
