DEVICE FOR CLEANING FLUE GASES Russian patent published in 2000 - IPC

FIELD: industrial furnace plants and thermal power stations. SUBSTANCE: longitudinal shutters are provided on outer surface of condenser located above smoke stack in form of dome; each element of shutters is made in form of wing whose profile corresponds to that of dome in contact zone. Lateral surface of truncated cone is provided with helical grooves in form of dovetail running from lesser base to larger one; helical grooves found at larger base of truncated cone are connected with chute of condensate trap. EFFECT: increased height of scattering contaminants; enhanced efficiency of cleaning flue gases due to intensification of heat and mass exchange under conditions of wind load. 3 dwg
