An exhaust gas cooler includes: a steam drum containing first water; an economizer for heat exchange between exhaust gas and the first water supplied from the steam drum; and a feedwater pipe for supplying the first water with second water having a lower temperature than the first water. The exhaust gas cooler is configured such that the first water flowing out of the economizer is introduced into the steam drum. The second water is divided and supplied to the first water flowing out of the economizer and the first water flowing into the economizer.
