A kind of carbon dioxide application device includes: that high/low temperature side flow path (20H) heat exchanger (20) receives exhaust gas that supply burning generates by combusting heavy oil in heater (10) and will be in burning waste gas In a kind of reduction burning waste gas of the low high temperature side flow path (20C) for the relative humidity of heat exchanger (20) It includes in burning waste gas that oxysulfide is removed in filter (40) A part of oxidation catalyst (50), in the burning waste gas including oxidizing carbon monoxide With a carbon dioxide adsorption equipment (70), first absorbing carbon dioxide includes the burning and gas-exhausting flow path (20C) of gasoline, which supplies heat from the cooling heat exchanger (20) by high/low temperature side flow path (20H) of heater (10) heating burning and gas-exhausting using from burning and gas-exhausting.
