Insufficiency of hk (hm of such heat exchangers is the uneven distribution of velocities in air chambers and, as a result, reliability of operation.

A heat exchanger is also known), containing a dead end pipe installed in a gas duct, divided by a longitudinal partition into the water supply and discharge compartments connected to each other and connected to the outlet and the second branch pipes 2.

A disadvantage of the known recuperators is the 1P13KY heat transfer coefficient when using them in bell-type chambers, equipped with vertical flue gas channels with small channels.

 of the invention is intensification 1. and those of loobla.

Delivered 1el is achieved by the fact that the heat exchanger, containing 1. installed the first pipe to the flue, divided the 1st i-long-SINGLE WATER into 1 DRAIN, IJ and waste compartments, communicated with N K between them and connected to the inlet and outlet nozzles, fitted with a casing with transverse rings, partitions, enclosing a dead-end pipe with formation of ring cavities, against which opposite by-pass openings are made in the dead-end pipe in the zone of inlet and outlet compartments.

The drawing shows the heat exchanger, obn1.iy view.

The recuperator contains the installation of a flue gas pipe 1, a split pipe 1, divided by a partition 2, a conduit 2 and a discharge pipe 4, respectively, connected to each other and, respectively, to the inlet 3 and B) 1 to 6 1 tubes.

The device works as follows.

The heat exchanger is installed in the bell-flue of the bell-type furnace so that the hot smoke is evenly washed over the casing 7. The dead-end pipe 1, the radiation in the heat exchange with the casing 7, is intensely heated.

Cold air through pipe 5 enters compartment 3 and through openings 10 exhausts into ring hollow 9. As it leaves cavity 9, cold air is distributed into two uniform streams and then each stream follows a circular path along the dead-end pipe

I in the direction of the holes 11.

The movement of air along a circular path is provided by the transverse annular hedge walls 8. 0. A path equal to half the circumference is now complete, the air is heated and through the holes

I1 enters compartment 4, and from there through pipe 6 to the burners of the bell-type furnace.

The main features of the offered recuperator are compactness, it is very necessary in the conditions of a bell furnace; a high degree of development of heat transfer surfaces of 1) with relatively low metal consumption (the heat transfer process involves the internal surface of the casing and both upper surface of the dead-end pipe); high ko: those transfer from the walls of the cylinders to the air, since it has a favorable place combining 1 slit effect, a circular trajectory of air movement (centrifugal effect) and a small thickness of the moving air layer, which intensively mixes with the movement; The entire surface of the heat exchanger is efficiently used to transfer heat to the heated air, since with the adopted pattern of its movement, the heat transfer process takes place with a large temperature difference between the wall of the heat exchanger and the air, as in the well-known slot recuperators with longitudinal air wash and heat transfer surfaces the temperature is reduced due to the preheating of the air as it moves 0 long distance; small aerodynamic CO2) since all the heated air, ro, rushes through the heat exchanger 1 in parallel with the multitude of short flows.
