Patent abstract
Heat recovery equipment recovers heat from flue gas. The heat recovery equipment includes a power generation plant that drives a steam turbine by superheated steam produced in a boiler, and an exhaust-gas treatment line that treats flue gas output from the boiler. The exhaust-gas treatment line includes a first air preheater, a heat extractor unit, and a dry electrostatic precipitator. The power generation plant includes a condensed water line. The condensed water line includes a condenser, a condensed water heater, and a low-pressure feedwater heater. The condensed water heater heats water condensed by the condenser with the heat recovered by the heat extractor unit.
