Abstract

The invention relates to energy and m. used to dispense liquid fuel (T). The invention makes it possible to simplify the operation of the nozzle. The T through the central opening of the housing 1 and the openings in the swirl chamber 2 is distributed in the annular space of the latter, from where it escapes through the outlet nozzle 3 to the furnace in the drip state. When T is twisted, under the action of centrifugal forces in the ejection chamber 2, abrasive particles having a large specific gravity are collected at the periphery of the swirl chamber 2 and enter the annular gap 4 and further into the pockets 5 and the input tangential channels 7 of the centrifugal nozzle 6. the abrasive particles fly out into the firebox, while a certain amount of T flowing out with the particles dissolves. 2 Il.

Description

The invention relates to a technique for spraying liquids, is intended primarily for spraying liquid fuel in power and power plants and is an improvement of the known invention according to the authors. St. No. 937883.

The purpose of the invention is to simplify the operation of the nozzle.

FIG. 1 depicts the proposed nozzle, a longitudinal section; in fig. 2 shows a section A-A in FIG.

The nozzle includes a housing 1 with a swirl chamber 2 and an output nozzle 3, an annular slot 4 and pockets 5. An additional gun 6 is installed in the center of the swirl chamber 2, the input channels 7 of which are connected to the pockets 5.

The nozzle works as follows.

The fuel is distributed through the central opening of the housing 1 and the holes in the chamber 2 in the annular space of the latter, from where it escapes through the outlet nozzle 3 to the furnace in the drip state. When the fuel is twisted in the swirl chamber 2 under the action of centrifugal forces, abrasive particles having a large specific gravity are collected at the periphery of the swirl chamber 2 and enter the annular gap 4, further into the pockets 5 and the inlet tangential channels 7 of the additional atomizer 6. abrasive particles fly into the furnace, while

some fuel flowing with the abrasive particles is sprayed.

Post pockets 5 with input

The 5 channels 7 of the driver 6 installed in the center of the swirl chamber 2 simplify the operation of the nozzle, since the nozzle acquires the self-cleaning property and eliminates the cleaning operation of the pockets 5 and the gap A from abrasive particles. However, the atomization quality does not deteriorate. The preservation of the quality of the spray is ensured by a spray

 - 6, through which a small amount of fuel and abrasive particles are passed.

The proposed nozzle is a single circuit, and the second stage (in this case, the sprayer 6) receives fuel, which is enriched with abrasive particles, from the chamber 2 in the first stage, and cannot be used to control performance in very wide ranges.
