Apparatus (1) for reducing the temperature of flue gases adiabatically in a flue gas stream comprises a duct (3) for the flue gas stream having an upstream flue gas inlet (20) and a downstream flue gas outlet (23). Nozzles (28) in the duct (3) adjacent the inlet (20) deliver a cooling water spray of droplet size which is not greater than 50 microns into the flue gas stream. An upstream baffle (35) formed by parallel spaced apart tubular baffle members (40) causes the water droplets to merge with the flue gases of the flue gas stream. The baffle (35) may comprise six baffle members (40) which form a baffle with a porosity of 50% and which occludes approximately 60% of the area of the flue gas inlet (20). Further baffle portions (36, 37) may be provided. <IMAGE> |
