FIELD: heating.SUBSTANCE: invention relates to devices for heating of domestic and industrial premises, in particular, to design of furnace flues. The flue-heat exchanger comprises a hollow body with inlet and outlet nozzles, inside of which there is a braking device for braking of smoke gases and heat exchange, besides, the braking device is made in the form of gates with slots, at the same time gates are installed inside the body and are fixed on transverse axes capable of rotation so that in the position, when the gates are arranged across the body, their slots form a zigzag gas duct, and on the axes outside the body there are levers fixed, free ends of which with the help of hinged joints are connected to a common rod for installation of the gates into the specified position.EFFECT: increased effectiveness of heat exchange by regulation of gates position for selection of optimal ratio of draught in a flue and effective heat exchange in a braking device, with preservation of high safety.7 dwg |
