STEAM PROVIDING SYSTEM AND CO2 RECOVERY FACILITIES PROVIDED WITH SAME

摘要

This steam supply system includes a reboiler (130) that raises the temperature of absorbing liquid contacted with exhaust gas discharged from a boiler to absorb CO 2 in the exhaust gas and heated to eliminate CO 2 . The reboiler (130) includes a heat exchanger tube (130a) to which steam for heating is supplied and a condensed water drum (5) that recovers condensed water (6) of the steam introduced from the heat exchanger tube (130a) as steam drain, and the condensed water drum (5) is provided with decompression unit that lowers pressure in the condensed water drum (5).
