An apparatus for cooling hot gas, for instance stack gas from combustion of solid, fluid or gaseous fuels, which can comprise water insoluble and/or insoluble pollutants, wherein the gas is cooled by being saturated with atomised water in at least one step, so that heat is transferred to the water and steam in the gas condenses and brings pollutants if present, which are separated from the water, whereafter the water is returned to the cooling apparatus as cooling water, said apparatus comprising: at least one U-shaped cooling chamber (4) provided with cooling means (2), for instance spray nozzles for adding cooling water in atomised form, at least one outlet for liquid from cooling chamber (4) and a thereto connected container (9) for collecting cooling water from the cooling chamber (4) and a heat exchanger (14) connected to the container (9); wherein the heated cooling water is cooled prior to being returned to the cooling means (2), wherein the apparatus forms a closed re-circulating system. |
