PURPOSE: A device for collecting waste water heat of a steam boiler is provided to reduce energy consumption and costs because water supplied to a boiler unit is heated by using waste water heat remained after using for a heat exchange in a heat using unit. CONSTITUTION: A device for collecting waste water heat of a steam boiler comprises a boiler unit(110), a facilities unit(120), and a waste heat pipe(130). The boiler unit heats the water and generates steam. The facilities unit heat exchanges by receiving steam of high temperatures. The waste heat pipe supplies water to inside an exhaust pipe in the state of being installed in the inner circumference of the exhaust pipe as a coil form, thereby preheating the water by using the steam of high temperature flowing inside the exhaust pipe. An auxiliary tank stores the waste heat remained after using for a heat exchange in the heat using unit in a fluid type.
