FIG. 7

And og) |) eteiiie refers to heat г ех ии ке ии ке исп and can be used in heat and power plants operating with persistent pressure in the combustion chamber or on gas 11e) emenio | -o pressure.

The aim of the invention is to, 1, expand the range of the regulating parameters of the flame.

On fi1. 1 shows a burner, a longitudinal section; on fis. Figure 2 shows the layout of the reflector in front of the radial holes; in fig. What is the location of the reflectate? 1 behind the radio holes.

, - | ka contains a housing 1, a central fuel-dispensing pipe 2 with radial ohrang 3 and a rotary displacement () reflector 4 with slots 5. () trashy. 1 4 is spaced to the zone of radio (pierstey 3 pipes 2, and its section 6, adjacent to pipe 2, discharge loifipnpoitanHbiM, and the number of corrugations 7 is equal to the number) holes 3.

The burner works as follows; c) m.

Air is supplied to Kcjpnyc 1, then passes through the slots 5 of the disk reflector 4 and, mixed with gas, coming out of the radio, 1H 51x holes 3, forms a gas-fired mixture, which, at the exit of the burner, burns.

By changing the position of the reflector 4 relative to the answer, step 3 (1 regulates the process of mixing.

FIG. 2

When the reflector is set to the position shown in FIG. 2, hectares; and) the outgoing jets are supplied through the openings 3 behind the reflector 4, i.e. the fuel is supplied to the recirculation zone of the combustion products with a small amount of air. The main amount of air to burn comes through the slots 5. At this m., The process of mixture formation slows down and the length of the flame increases.

When installing the reflector in the position shown in FIG. 3, i.e., when the reflector 4 is rotated on the corrugation 7, gas jets are supplied through the openings 3 into the channel in front of the reflector 4 and, spreading along the grooves formed by the corrugations 7, are evenly distributed, 1 in the air flow. The process of mixing is intensified, gas-flow is fed through the slits 5 to the mixture, and the length of the plume is shortened.

Claims (1)

Invention Formula The burner containing the cornea, the central fuel-discharging pipe with radial holes and the rotary disk reflector with slots, is characterized in that, in order to expand the range of control of the torch parameters, the reflector is spread in the area of the radial holes of the pipe and its section adjacent to the pipe corrugated, and the number of corrugations is equal to the number of these holes.
