MULTICLONE Russian patent published in 2003 - IPC

FIELD: gas cleaning equipment; preparation of atmospheric air for delivery to compressor of gas- turbine engine. SUBSTANCE: proposed multiclone protects blading system against abrasive wear and inlet members of gas-turbine engine and inner surface of cleaned air passage against icing. Multiclone includes air intake chambers arranged in tiers with cyclone components, precipitation baffles, clean gas discharge manifolds, dust collectors of tiers and air heating system with gas ducts for delivery of hot air. Gas ducts of air heating system are located horizontally on outer sides of rear walls of air intake chambers below outlet section clean air discharge manifolds; they have holes directed to side opposite to rear wall of air intake chambers; these holes may be made in form of slots. Icing of suction passage is excluded due to change of heating zone. EFFECT: enhanced efficiency; reduced consumption of hot air from engines. 2 cl, 2 dwg
