Description

(54) BURNER

The invention relates to heat engineering, in particular, to devices for burning gaseous fuels, and can be used in all branches of the national economy under conditions of application in burners of gases and blast air with a high content of mechanical moisture and dust.

A known burner comprising a housing formed in the form of a tee, which consists of an upper branch pipe of the body serving to supply gas to the burner, a cylindrical part attached through a shut-off valve to the combustion chamber of the air heater and a horizontal pipe connected through a branch pipe on the opposite side of the air heater. Body with blow air fan. From the bottom, on the front of the housing, there is a valve with a vent hole for venting condenser tl from the housing.

However, in a known burner, when a blast furnace gas is supplied with an increased

by keeping mechanical moisture and blast air with a high content of dust, due to the direct flow of gas and air into the combustion chamber of the air heater, only a small part (O, 3%) of mechanical moisture is captured and discharged through the pocket with a drain hole. Dust and moisture of the blast air are not trapped at all and enter directly into smoke gases passing through the air heater nozzle. The entry of dust from the blast air and mechanical moisture into the combustion of the air heater reduces the efficiency of the use

15 and leads to the overgrowing of the air heater nozzle, and consequently, the reduction of its service life.

Closest to the proposed, the top 20 contains a case with a spout pipe dispersed in iieM, equipped with gas air-nozzles with swirls. G2, 396 Nedbigakkom this burner is low efficiency due to the presence of a large number of mechanical impurities in the initial agents. The purpose of the invention is to increase the efficiency of the device by cleaning the source from 1D) 1X agents from mechanical impurities. This goal is achieved by the fact that in the burner in the inlet areas of the gas and air supply nozzles behind the swirlers, annular collection pockets of impurities, communicated with each other through the water seal, are additionally integrated with them. Fig, I shows the burner, section; Fig. 2 shows the arrangement of the gas and air swirl blades and the water seal, the burner holds the housing 1 with a pipe 2 placed in it with a gap, equipped with a gas guide 3 and air supply 4 pipes with swirlers 5. In the inlet sections of pipes 3 and 4 for the swirls In addition, the circular pockets 6 of the collection of pipes, connected to each other through a hydraulic lock 7, are in line with them 5 coaxially with them. The gas burner works in the following way. The gas containing droplet moisture unwinds in the swirler 5 pipe 3, Concentrated on the outer ring of the swirler 5 moisture, mixing along the axis of the pipe 3, is trapped in the pocket 6 and discharged through the air trap 7 into the swirl 5 blast air. In the swirler 5 of the nozzle 4 moisture condensate from the blast furnace gas forms, with air dust, an annular mass exchange layer, in which the air is cleaned from dust. Moisture from trapped dust enters pocket 6 and is discharged into the sewer. Thus, the installation of pockets for trapping mechanical impurities from the initial agents supplied for combustion increases the efficiency of the proposed burner compared with the known I, Invention Burner, comprising a housing with a pipe placed in it with a gap, equipped with gas and air inlets with swirlers, characterized in that, in order to increase the efficiency by cleaning the initial agents from mechanical impurities, in the inlet areas of the above-mentioned pipes for swirling ™ and coaxially with them are further integrated. collecting mana impurities communicated between them through the water trap.
