우회라인을 포함하는 이산화탄소 포집 저장 시스템이 개시된다. 상기 우회라인을 포함하는 이산화탄소 포집 저장 시스템은, 배기가스를 배출하는 연소부; 제1 순환수가 배기가스에 함유된 이산화탄소를 흡수하는 흡수부; 상기 흡수부로부터 공급받은 이산화탄소를 흡수한 제1 순환수와, 상기 연소부로부터 배출된 배기가스를 열교환시키는 열교환부; 및 상기 연소부로부터 배출된 배기가스의 일부 또는 전부를 상기 열교환부를 우회시켜 상기 흡수부로 보내는 우회라인;을 포함하고, 상기 열교환부 내의 제1 순환수의 온도가 일정 온도 이상이 되는 경우, 상기 연소부로부터 배출되는 배기가스를 상기 우회라인에 의해 상기 열교환부를 우회시켜 상기 흡수부로 보낸다. The invention discloses a carbon dioxide capture and storage system and method. The carbon dioxide collection and storage system includes: a combustion unit that discharges exhaust gas; an absorption unit for absorbing carbon dioxide contained in the exhaust gas by means of the first circulating water; and a heat exchange part which exchanges heat between the first circulating water which is received from the absorption part and absorbs carbon dioxide and the exhaust gas discharged from the combustion part, and the exhaust gas discharged from the combustion part is cooled by the heat exchange part and then is supplied to the absorption part. The first circulating water, which absorbs carbon dioxide and is supplied from the absorption unit to the heat exchange unit, is heated by the heat exchange unit and carbon dioxide is separated.
