Description

The invention relates to the field of heat exchange and can be used in regenerative heat exchange devices, in particular for high-temperature heating of gas in the iron and steel industry.

The purpose of the invention is to intensify the heat exchange between the gas and the nozzle, as well as to increase the strength of the latter.

FIG. 1 shows the nozzle element; on

the grooves 4 range from 0.05 to 0.4 times the thickness h of the element 1.

The nozzle works as follows.

Combustion products (smoke) with a temperature of 1300 ° C and above, as well as slag particles, enter the nozzle from above and pass through vertical channels 2, give off heat to refractory elements 1. Due to the semi-cylindrical shape of the upper part of elements 1, slag dust does not settle on them and

FIG. 2 - nozzle assembly, longitudinal fold-U does not overlap the cross-section of channels 2. Through

rez; in fig. 3 - the same, axonometrics. A certain period, the flow of combustion products is turned off and through the nozzle from the bottom.

The nozzle of the regenerator contains refractory-upward air is passed through or another heated element 1 (bricks), installed gas.

over each other by horizontal rows. As shown by comparative tests,

to offset by 90 ° in each subsequent relative volume coefficient of heat and the formation of vertical channels 2 and horizontal aisles 3. Each element 1 in the upper part is made semi-cylindrical with transverse grooves 4,

repeating the shape of the lower part of the size-20 0.05 to 0.4. In addition, the adjacent elements of the adjacent upper ridge have a lower hydraulics. The lower parts of the elements 1 are made of resistance, as well as a larger procprismatic form (in particular, due to the shape of the lower part of the element of the parallelepiped), and the depth C (Fig. 1) of the cops is 1.

the lot of the proposed nozzle exceeds that for a nozzle of cylindrical elements in the interval of the depth of the grooves and the height of the refractory element from
