| 1. Heat recovery equipment for recovering heat from flue gas, comprising:
a power generation plant that drives a steam turbine by superheated steam produced in a boiler, the power generation plant
including a condensed water line, the condensed water line including a condenser, a condensed water heater, and a low-pressure
feedwater heater in order; and
an exhaust-gas treatment line that treats flue gas output from the boiler, the exhaust-gas treatment line including a first
air preheater, a heat extractor unit, and a dry electrostatic precipitator in order, wherein
the heat extractor unit recovers heat from the flue gas, and
the condensed water heater heats water condensed by the condenser with the heat recovered by the heat extractor unit.
