CHIMNEY Russian patent published in 2021 - IPC F24B7/00 F23J11/00 E04F17/02 

FIELD: residential heating.

SUBSTANCE: invention relates to the heating of premises with the help of chimneys, as well as to devices for removing exhaust chimney gases from heating devices. The chimney includes smoke elements mounted in a predominantly vertical structure from the bottom up. The chimney includes a base with a container for collecting condensate, a cleaning tee with an inspection door, at least one vertical pipe, a tee for connecting to the stove, which is connected to at least one heat exchange pipe from above. The stove connection tee on the side is connected to a horizontal pipe, which is connected to the 90° outlet for connecting to the stove. The smoke elements are made of solid cast iron and are connected to each other by cast-iron couplings, inside of which the collars protrude in the middle, equipped on both sides with a chute for laying the insulation cord on the sealant. On the outside of the heat exchange tube along its entire length, horizontal ring-shaped projecting ribs are made, which serve to increase heat transfer. The heat exchange tube is provided with a lid on top.

EFFECT: increased chimney efficiency due to higher efficiency of heat removal, increased efficiency of heat transfer to the surface of the projecting ribs by making them all cast, increased reliability of the chimney due to the use of chimney elements made of cast iron.
