horizontal cyclone furnace.

The utility model relates to the field of c: burning fuel and can be used in the energy sector and in hghi with c: kngan1sh technological substances: sulfur, hydrogen sulfide, etc.

Known cyclone furnace containing 1; il1shdrichvsku1a liningHHjTto combustion chamber with an air jacket and an exit window, a device for supplying fuel and primary air mounted on the front end of the combustion chamber, and a swirl secondary air | 1.

A disadvantage of the known furnace is the high heat stress, which makes high demands on the quality of the lining and creates favorable conditions for the formation of K / 0 oxides.

To eliminate this drawback, two-stage cyclone furnaces have been created.

A horizontal cyclone furnace is known, consisting of cylindrical lined forkaglers and two chambers with an air jacket separated by clamps sj. Nozzles for supplying fuel and primary air are tangentially installed in the middle part of the prechamber. In the first afterburning chamber, nozzles for supplying fuel and secondary air are also installed tangentially.

A disadvantage of the known furnace is the increased complexity of the design.

The purpose of the utility model is to create a cyclone furnace, which increases the outfit of work and reduces the yield of oxides 0.

This goal is achieved by the fact that in the horizontal cyclone furnace the outlet window is made in the form of a nozzle in front of which secondary air nozzles are installed on the side surface of the combustion chamber.

In FIG. I schematically shows a cyclone furnace, a longitudinal section; on f11G. 2- sections BB and 3 - In FIG. I.

The horizontal cyclone furnace contains a cylindrical lined chamber I with an air jacket 2, a blind front spherical end 3 and an exit window 4 in the rear end 5. In the middle part of the combustion chamber I 3, fuel supply nozzles 6, for example, hydrogen sulfide 2 with primary air 7, are installed. 7. On the lateral side The combustion surface I in front of the rear end 5 has tangential nozzles for supplying secondary air 8.

Into the combustion chamber I through nozzles 6 and 7, tangentially to its wall, hydrogen sulfide and primary air are supplied. The vortex formed during the kx movement during rotation splits into two, one of which moves to the exit 1–1 window 4, and the other to the front front spherical at the end 3. On the wall of the latter, this angle, deviating to the longitudinal axis of the furnace, makes the degree of twist, so as the radius decreases, it concentrates and, reflected from the wall, moves to the outlet at the window inside the primary vortex. In this case, the combustion process is extended, as it were, along the combustion clasher, the electrical stresses are aligned, and since only part of the air necessary for the combustion of sulfur is supplied through the nozzle 7, the combustion level in the combustion chamber I is not maximum. This leads to an increase in the lining resistance and a decrease in the formation of oxides / 0 .. For the combustion products to burn two vortices before entering them in the nozzle 4 (as well as cooling the rear end 5 and the nozzle 4 itself), secondary air is introduced into them through the nozzle 8. The process of vigorous mixing of gases and burning out of sulfur takes place in nozzle 4. From the cyclone furnace, the gases enter the boiler for cooling and then to the subsequent apparatus.
