Abstract: Wash liquor/ suspension is sprayed at a velocity of at least 8 m/s, such that the atmosphere above the sump liquid surface contains at least 0.5 % wash suspension. Cleaned gas is discharged via a side outlet (13). An Independent claim is also included for a scrubbing tower having a sump of greater cross sectional area. The sump may be provided with a propeller agitator (15) for turning-in gas to the sump liquid in order to further increase gas-liquid contact time.

Abstract: 92/078 In a secondary burner for a gas turbine combustion chamber, a fuel feed (2, 3) arranged in a combustion chamber wall (1) is surrounded by an annular air duct (4). The air duct (4) communicates, by means of at least one supply tube (5), with a through-flow Helmholtz resonator (6). The outlet from the Helmholtz resonator damping tube (7), which is configured as an annular duct, is located in the region of the burner mouth (8) in the secondary combustion space (9). (Fig. 1)
