Beschreibung
Zusammenfassung:	This invention provides a heat recovery and utilization system for efficiently utilizing heat recovered from boiler exhaust gas with a heat recovery unit without any complicated equipment or high operation costs. The heat recovery and utilization system includes: a boiler 11 for electricity generation; a heat recovery unit 13 for recovering heat from exhaust gas of the boiler; a heat exchanger 21 for using heat recovered with the heat recovery unit as heat source for equipment other than for electricity generation; a heat accumulator 31 for accumulating heat source for the equipment other than for electricity generation; and a heat medium circulation line 22 in which heat medium circulates between the heat recovery unit and the heat exchanger to exchange the heat recovered with the heat recovery unit with the heat exchanger. Upon startup of the system, the heat exchanger 21 preheats the heat recovery unit 13 with heat source accumulated in the heat accumulator 31.
