METHOD AND DEVICE FOR CHECK OF INNER CIRCULATION IN FLUIDIZED-BED REACTOR AND FLUIDIZED-BED REACTOR USED FOR REALIZATION OF THIS METHOD

摘要

FIELD: check of consumption of solid particles in the course of inner circulation in fluidized bed of reactor. SUBSTANCE: reactor has lower zone to which fluidizing gas is injected and upper zone bounded by walls. Device has tank for taking 100 solid particles from flow of inner circulation; tank is secured to wall 4 of reactor and is provided with fluidizing units 1-2, pipe line 110 for discharge of solid particles from tank 100 in way of device 130 used for measuring the consumption of solid particles and pipe line 120 for return of solid particles to inner cavity of reactor. EFFECT: possibility of checking the flow rate or inner circulation through continuous measurement of this flow rate. 15 cl, 8 dwg
