| 摘要 |
The invention relates to a method and a device for treating fluid streams produced during the combustion of carbon- and ash-containing fuels. The aim of the invention is to optimally utilize the heat content present in the system as well as the amount of water for cooling and condensation required during the recirculation of the latter. The method according to the invention is characterized in that the suspension withdrawn from the mixing vessel is expanded in at least one subsequent step during the evaporation of at least part of the water and reduction of the temperature and in that the vapor produced is cooled by direct contact with water and at least partially condensed out. The device according to the invention is characterized in that a line (6) between a lower section of the mixing vessel (1b) leads to a first expansion vessel that is designed as a scrubber tower (7a), the scrubber tower being provided with a condensate collection bottom (8a) and a recirculation line (10a) towards the mixing vessel (1b) for the forming condensate, which mixing vessel is equipped with spray heads. |
