Description

I

The invention relates to burners and can be used in industrial heat and power.

Known burner devices containing enclosed in a casing with an annular gap for the air outlets, covered with a refractory mass of the combustion chamber with an inlet section in the form of a diffuser, have an annular air channel at the outlet, and an inlet channel for supplying primary air with a swirler installed on the nozzle axis and a peripheral gas manifold.

The purpose of the invention is to increase the completeness of the combustion of high viscosity sulfur fuel oil. For this, the entrance section of the combustion chamber is made narrowed with a water-cooled diaphragm. There are radial holes in the middle part of the diffuser for air supply, and a swirler is installed in the annular air channel.

The drawing shows a predlozhenny device, a longitudinal section.

The burner device contains a small-volume combustion chamber, the working volume of which is limited by the output diaphragm /, the cylindrical body 2 and the diffuser. The diaphragm / consists of an inner ring 4, an outer ring 5, an infrequent wall 6 and a back wall flange 7. The fittings 8 and 9 are welded to the bottom and top of the outer ring 5

respectively for the entry of cooling water and its withdrawal. Cylindrical cornea 2 is attached to flange 7. From within, cornea 2, diaphragm I and diffuser 3 are welded with steel tires and they have a refractory mass 10. They are welded to the body 2 by longitudinal ribs 11, which are fitted with shell 12. Casing 13 with nipple 14 serves for air supply. A diffuser 15 is welded to the diffuser 3, which has radial holes a, and a gas collector 16 with fitting m. 17 and outlets b. At the entrance to the diffuser 5 is installed swirl containing the lap 18, ring 19, the bottom 20 and

a sleeve 21 into which a centrifugal mechanical nozzle 22 is inserted.

The air from the blower fan with the outside air temperature enters through the pipe 14 into the space between the skins: ear 13 n shell 12 and is directed towards the exit diaphragm /, rotates 180 ° and enters the space between the cornea 2 and the shell 12, heat up and cooling the casing 2. Next, the air is divided into three streams. The first stream enters the sealer 15, twists and enters the combustion chamber. This air flow} is maintained due to the centrifugal effect of the particles of the tonnes that fall into the near-wall region, and afterwards

The second stream of air enters his chamber

Runs radially in the form of a jet through the holes a, mixes the top.tivo with air and saturates the central zone of the torch with oxygen. The third tray of air enters the chamber swirled through the tilts 18. This stream plays the role of primary air. The fuel is fed into the chamber by a centrifugal spray nozzle 22. The chamber evaporates, gasifies the fuel, mixes it with air, burns out a significant part of the gasified fuel, the remainder of which burns completely into the boiler furnace, thereby preventing the formation of secondary soot. The output diaphragm / keeps large particles of fuel that have not passed gasification out of the chamber. To prevent overburning, the exit orifice plate is cooled by mains water.

Subject invention

The burner contained in the enclosure with an annular gap for

passage w; ha. or a combustion chamber with an opaque mass and with an inlet section in the diffuser's zide, which has an annular air channel at the outlet, and an inlet channel for the primary air with a swirler installed on the axis of the nozzle and a peripheral gas collector at the inlet, characterized in that it is Combustion of high-viscous sulfur fuel oil, the entrance section of the chamber has been narrowed with

water-cooled diaphragm, in the middle part of the diff | (|); pattern. Radial holes for air supply are provided, and a swirler is installed in the annular air channel.
