| 摘要 |
<p>The invention relates to a device for purifying and recovering energy of flue gases from a boiler (2). The device comprises a quench unit (1) adapted to receive the flue gases from the boiler, and to add water to the flue gases in order to achieve cooling and higher moisture content of the flue gases, a condenser unit (9) adapted to receive flue gases at from the quench unit, to condense the flue gases to a liquid and thereby recovering energy from flue gases, and a purifying unit (10) adapted to receive the liquid from the condenser unit, to purify the liquid and separate it into a purified part including essentially purified water and a contaminated part including contaminated water. The device comprises means (18) for supplying at least a fraction of said contaminated part of the liquid to the quench unit, and the quench unit comprises means (5,4) for adding said contaminated part of the liquid to the flue gases in order to achieve cooling and higher moisture content of the flue gases.</p> |
