To provide heat recovery equipment capable of improving power generation efficiency in power-generating facilities by effectively utilizing heat of a power generation plant.
This heat recovery equipment includes: the power generation plant 10 driving a steam turbine 13 by superheated steam 12 from a boiler 11, and having a low-pressure feedwater heater 16 applying low-pressure extraction steam from the steam turbine 13 as a heating source, and a high-pressure feedwater heater 18 heating the feedwater superheated by the low-pressure feedwater heater 16 while applying high-pressure extraction steam from the steam turbine 13 as a heating source through a boiler water feed pump 17; an exhaust gas treatment line 20 including an air preheater 21 for recovering heat of the exhaust gas from the boiler 11, and a dry electric dust collector 22 for collecting power dust in the exhaust gas; a heat recovery unit 31 disposed between the air preheater 21 and the dry electric dust collector 22 disposed in the exhaust gas treatment line 20; and a condensed-water heater 32 disposed between a condenser of a condensed-water line and the low-pressure feedwater heater 16 of the power generation plant 10, and heating the condensed water by the heat recovered by the heat recovery unit 31.
