METHOD AND DEVICE FOR CATCHING CHIMNEY EMISSION Russian patent published in 2007 - IPC F23J15/00 

FIELD: heat power engineering.

SUBSTANCE: device comprises housing covered with a conical shield and provided with bottom conical chamber for collecting condensate, air heat exchanger coaxially mounted inside the housing, and base mounted on the head of the chimney shaft and provided with the air heat exchanger. The housing is provided with the cylindrical funnels for sucking cold air and discharging cleaned gases, the shell of the air heat exchanger provided with straight flow pipe bank with transverse supporting cross-pieces made for permitting change of the direction of air sucking into the interpipe space and mounted with a minimum space 1-3 mm in the oval opening in the sloping plate welded to the housing. The edge of the plate is flanged upward to define a sloping chute for descending the contaminated condensate. The base is shaped into the ring and provided with oval ports inclined to the side and receiving tips made of magnetic steel sheet and used for control of the magnetic field. From one side of the base, there is a cooled magnetic catcher connected with the space and branch pipe for collecting and removing condensate. In front of the catcher, there is a funnel for sucking a part of the hot chimney gases with dust from under the bottom tube bank of the air heat exchanger to the system for recirculation of the chimney gases. The method for catching emissions is also described.

EFFECT: expanded functional capabilities.
