MULTISECTION UNIT OF HEAT GENERATOR FUME GAS TREATMENT AND UTILISATION IN INDEPENDENT HEAT SUPPLY SYSTEM Russian patent published in 2009 - IPC F23J15/00 

FIELD: heating.

SUBSTANCE: invention concerns thermal power industry, particularly heat supply, and can be applied in heat and condensate treatment and utilisation of fume gas generated by thermal generators of independent heat supply systems. Multisection treatment and utilisation unit for fume gas of heat generator in independent heat supply system includes input gas collector with bottom holes featuring sectional sliding gates, to which sections are attached. Sections include ridged vertical cooling and condensation columns separated by air gaps and connected to each other and to treatment column with removable sideboard by collectors. Removable perforated flanged chutes are installed in checkerboard order inside treatment column and filled with hydrated lime (Ca(OH₂)) chips. Treatment column features conical bottom and removable sideboard, column top is connected to gas outlet collector and to funnel with deflector, and column bottom is connected to purified condensate collector by a slit. Columns of all sections are placed inside housing covered at opposite ends by removable cap with ventilator and by cap with hot air pipe.

EFFECT: improved economical and environmental efficiency of multisection unit of fume gas treatment and utilisation.
