The fuel pipe 7 is bonded to the fuel inlet 8 by an elastic link 19. The exit nozzle 9 in the rear end wall 10 can be blocked by a flat ceramic plate with outlet openings (BO). The VC has contact with the CS in the zone of wall 10. In the internal cavity of the heat exchanger, in the zone of the VC and around the CS, water cooling is installed, the annular tube 22 is priced. 17 is made of ceramic, the COP is thin-walled and removable. When the burner is operating, gas and air are supplied to the nozzle 9 or to the VO, as well as to the openings 18, at a speed of about m / s. The total passage area of the openings 18 for secondary air to the total cross-section of the nozzle 9 and the hole is 10-50%.

The invention relates to a power system, namely to the combustion of gaseous or liquid fuels in industrial burners for heating the working space of industrial furnaces. : The aim of the invention is to reduce the content of nitrogen oxides in combustion products.
Figure 1 shows the proposed burner, a longitudinal section; in figure 2; the same example of implementation; figure 3 -; view along arrow A in FIG. 2; 4 - I, the combustion chamber with a fan-like position of the outlet openings in the ceramic plate; FIG. 5 is a view along arrow R in FIG. 4.
The burner contains an air supply housing 1 placed in the housing 1 with an annular gap 2 pipe 3 primary
air, a combustion chamber 4, to the front end wall 5 of which, having evenly spaced apertures 6, are connected a fuel pipe 7 connected to the fuel pipe 8, and confused output nozzle 9, made in the rear end wall 10 of chamber 4, as well as shell 11 with the outwardly bent outward edge 12 and inwardly bent outward edge 13 installed in the annular gap 2 around chamber 4 with the formation of the inner and outer annular cavities 14 and 15 of the recuperator.

The internal cavity 14 has an outlet nozzle 16.
The output edge 13 of the shell P is installed in contact with the outer wall I7 of the chamber 4 and is pressed against the wall 17 by an elastic force acting on the chamber 4. The exit nozzle 16 of the internal cavity 14 is formed in the form of a system of holes 18 located circumferentially in the outlet edge of the shell P.
The fuel pipe 7 is bonded to the fuel pipe 8 by an elastic link 19.
The exit nozzle 9 in the rear end wall 10 may be blocked by a flat ceramic plate 20 with outlets 21.
The output edge 13 may have contact with the camera 4 in the area of the rear end wall 10.
In the inner cavity of the heat exchanger in the area of the output edge 13 of the shell I 1 and around the chamber 4 a water-cooled annular pipe 22 is installed.
The exit edge 13 may be provided with a ceramic reflecting screen 23 with apertures 24 coinciding with the apertures 18 in the edge 13.
Wall 17 is made of ceramic.
Chamber 4 is thin-walled and removable.
The holes 6 in the wall 5 have a total cross-sectional area,
the excess area of the flow area of the outlet nozzle 9 of the chamber 4.
Inlet openings 21 of the plate 20 are evenly spaced around the circumference, with the smallest distance between the edges of the adjacent pin holes 21 being larger than the nominal diameter of each of these holes 21.
The smallest distance from the edge of each hole 18 in the output edge 13 to the edge of the nearest outlet hole 21 of the plate 20 is more than three times the nominal diameter of the hole 18 in the edge 13.
The axes of the outlet openings 21 can be parallel to the axis of the openings 24 or intersect them, and with respect to the axis of the chamber 4, the axes of the openings 21 are fan-shaped.
During the operation of the burner to the outlet nozzle 9 (Fig. 1) or to the openings 21 (Fig. 2), as well as to the openings 18, with a speed of about 100 ,, .., 150 m / s, which corresponds to a pressure drop from 1 up to 2 kPa, preferably 1.5 kPa, enters the gas and air. The proportion of the total flow area of the holes 18 for secondary air to the total cross section of the outlet nozzle 9 and the hole 21 is 10-50%, preferably 30%. In order for the torch to be stable, the inner diameter of the chamber 4 and its length must be equal to 2, ..., 4 diameters, preferably three diameters of the nozzle 9.
