<p>The smoke gas is treated with washing liquid in a desulphurisation device (6). A part quantity of the heat energy is, via a heat exchanger (2, 5) lying in the smoke-gas flow (A), extracted from the smoke gas entering the desulphurisation device (6). This part quantity is supplied by a heat transfer medium in a closed circuit (3, 4) to a further heat exchanger (9, 8) which is acted upon by the smoke-gas flow leaving the desulphurisation device (6). The departing smoke-gas flow (B) then reabsorbs this part quantity of the heat energy. By means of such an arrangement, the heat quantity of the smoke gas necessary for the lift can for the most part be maintained, even if said smoke gas runs through the desulphurisation device (6) which works at a lower temperature. <IMAGE></p> |
