METHOD FOR AUTOMATICALLY CONTROLLING OPERATION OF ELECTRIC FILTER OF BOILER AGGREGATE

摘要

FIELD: power machine engineering, possibly electric filters for heat and power plants. SUBSTANCE: method comprises steps of using system for removing dust out of discharge hole of hopper when predetermined level of filling discharge hole of hopper is exceeded; determining dust content in flue gases according to its concentration in discharge hole of electric filter; using transporting sectional pipeline for removing dust out of hopper; performing dust fluidizing in each section and then moving dust together with rising flow formed in rising portion of said pipeline; removing part of fluidizing agent out of upper cavity of rising portion of pipeline to upper cavity of hopper and moving dust along inclined portion to next section of pipeline; determining value of predetermined level of filling discharge hole of hopper and effective cross section of inclined portion of transporting pipeline with use of relations given in description of invention for such calculations. EFFECT: enhanced efficiency, improved reliability of electric filter. 3 dwg
