PROBLEM TO BE SOLVED: To provide an exhaust heat recovery system which achieves a combined power generation system achieving both an increase in the power-generating capacity of an exhaust heat power generation facility and recovery of cold by an absorption refrigerating machine and which has higher efficiency by using an exhaust heat recovery boiler with middle/low-temperature exhaust gas as a heat source.SOLUTION: In the exhaust heat power generation facility, hot water generated by an economizer 11 is sent to a flasher 16 to recover steam and high-temperature water, the recovered steam is supplied to the low-pressure stage of a steam turbine 21, and also the recovered high-temperature water is used as feed water for the economizer 11. A part of or the whole high-temperature water recovered in the flasher 16 is supplied as the heat source to the absorption refrigerating machine 31, and circulating hot water whose temperature is lowered by the absorption refrigerating machine 31 is added to the feed water to lower the temperature of the feed water to the economizer 11. Thereby, the amount of heat recovered in the economizer 11 is increased, the amount of steam and high-temperature water recovered in the flasher 16 is increased, and electric-generating capacity and the amount of cold water obtained by the absorption refrigerating machine 31 are increased. |
