METHOD AND DEVICE FOR PROVIDING PLANTS AND/OR ALGAE WITH HEAT AND CARBON DIOXIDE WITH APPLICATION OF POWER PLANT FLUE GASES Russian patent published in 2015 - IPC A01G9/24 

FIELD: chemistry.

SUBSTANCE: method includes supply of flue gases into primary heat exchanger (5) to realise first heat exchange with air and supply of hot air into greenhouse with plants (6) and/or installation for algae cultivation (9). After that, part of flue gases, cooled in primary heat-exchanger, is supplied into secondary heat-exchanger (12) to carry out second heat exchange with air and cool flue gases to temperature, required for additional intake of carbon dioxide. After that, the process of obtaining carbon dioxide from flue gases and supply of carbon dioxide into greenhouse with plants and/or tank for carbon absorption of installation for algae cultivation is realised. Device consists of main pipe for carbon dioxide supply (4), connected with exhaust fan (3), primary heat exchanger (5), main pipe for flue gas discharge (1), connected with flue, secondary heat exchanger (12), device for CO₂ absorption under alternating pressure (14) and reservoir for CO₂ storage (16).

EFFECT: device construction reduces energy loss and environment pollution, caused by direct emission, due to considerable utilisation of flue gases, increases plant or algae yield in winter time period.
