FIELD: mechanical engineering. SUBSTANCE: washable unloading chute-type device for impact-type solid particles separator is used in circulating fluidized bed boilers; it includes set of funnel-shaped chutes 36 located on lower end of each baffle member 38 of impart-type solid particles separator 16. Funnel-shaped unloading chutes 36 interfere with accumulation of entrapped particles letting particles entrapped by baffle members 38 fall through them excluding flowing of flue gas around lower ends of impact-type solid particles separator 16. outlet parts 42 of funnel-shaped unloading chutes 36 have the same area of open surface for through falling of entrapped particles as that of baffle member 38 connected with it. EFFECT: reduction of flow of gas around separator; reduction of corrosion of convective heating surfaces. 17 cl, 10 dwg
