PURPOSE:To permit a circulatory use of carbon dioxide and contrive the reduction of a global greenhouse effect by a method wherein carbon dioxide in exhaust gases is absorbed by water, this water is supplied into a culture basin to cultivate algae by fixing the carbon dioxide in the water thereto and such algae are separated from the alga contg. water for use as a fuel. CONSTITUTION:The exhaust gas generating by burning a fuel 9 in a combustion furnace 1 is sent out from a blower 2 and thereafter discharged partially from a smoke stack 10 and the great portion thereof is sent into an absorption tower 3, whereby carbon dioxide in the exhaust gas is absorbed by sea water and this liq. is supplied into a culture basin 5 by a pump 4. In the culture basin 5, algae are cultured with the carbon dioxide fixed thereto by the photosynthetic reaction as a structural source of the algal components. The sea water contg. the algae thus cultivated in the culture basin 5 is sent by a pump 6 into a dehydrator 7 to separate the sea water from the algae and such algae are dried in a frying furnace 8 and the dried algae are supplied into a combustion furnace 1 for use as a part of the fuel. On the other hand, the sea water produced in the dehydrator 7 is sent into the water absorption tower 3, thus a circulation of the water being produced for its repeated usage. |
