(54) ПОГРУЖНАЯ ГОРЕЛКА(54) SUBMARINET BURNER

II

Изобретение относитс к области тепртотехники , а именно к погружным горелкам и может примен тьс на различных энергетических установках дл вьтаривани дл нагрева жидкостей.The invention relates to the field of heat engineering, in particular to immersion burners, and can be used in various power plants for heating for liquids.

Известна погружна горелка, содержаща камеру сгорани с .запальником, подключенную 1орцом к выхлопному патрубку , по периферии которого размещена соосно с образованием кольцевого зазора циркул ционна обечайка .A well-known submerged burner containing a combustion chamber with an igniter, connected by means of an end cap to an exhaust manifold, on the periphery of which is placed coaxially with the formation of an annular gap circulating shell.

Недостаток тсазанной горелки заключаетс в низкой эффективности из-оа того , что зона теплообмена продуктов сгорани с жидкостью ограничена кольцевым зазором между циркул ционной обечайкой выхлопным патрубком.The disadvantage of the tsazannaya burner lies in its low efficiency due to the fact that the heat exchange zone of the products of combustion with the liquid is limited by the annular gap between the circulation shell of the exhaust pipe.

Цель изобретени - повышвкке эффективности .The purpose of the invention is to increase efficiency.

Это достигаетс тем, что погружна горелка снабжена пучком параллельных труб, установленных поперек выхлопног патрубка и шфкул шионной обечайкл с наклоном относительно их продольной осиThis is achieved by the fact that the submerged burner is provided with a bundle of parallel pipes installed transversely to the exhaust pipe and to the shfkule of the shion shell with a slope relative to their longitudinal axis.

а торцы труб пучка закреплены в стенке обечайки.and the ends of the beam tubes are fixed in the wall of the shell.

На чертеже дана погружна в разрезе.The drawing given is submerged in section.

Горелка содержит сгорани I с запалышком 2, подключенную торцом к выхлопному патрубку 3, по периферю которого размешена соосно с образованием кольцевого зазора циркул ционна обечайка 4. Поперек выхлопного патрубка 3 и циркул ционной обочайки 4 с наклоном относительно их продольной оси установлен пучок параллельных труб 5, причем торцы этих труб закреплены в стенке обечайки 4.The burner contains combustion I with a torch 2, butt-connected to the exhaust pipe 3, the periphery of which is placed coaxially with the formation of an annular gap circulating shell 4. A beam of parallel pipes 5 is set across the exhaust pipe 4 with a slope relative to their longitudinal axis 5 and the ends of these pipes are fixed in the wall of the shell 4.

Горелка работает следующим образом.The burner works as follows.

Claims

The flow of combustion products comes from the combustion chamber I to the exhaust pipe 3 and, passing through its intertubular space, transfers some of the heat to the liquid through the walls of the exhaust pipe 3 and pipes 5. At the same time, the pipes 5 receive the liquid outside the circulation 3 shell 4 and by heating moves along them from below, going beyond shell 4. Then the partially cooled products of combustion. flow from the exhaust pipe 3 into the annular gap between the circulation shell 4 and the exhaust pipe 3, mix with the liquid, and with it rise up, heat and evaporate the liquid. The heated fluid flows through the upper end of the shell 4 to the outside, and the vapor gas formed is separated from the liquid. Installing a bundle of parallel pipes 5 across the exhaust pipe and the circulating shell with an inclination relative to their longitudinal axis and fixing their ends in the wall of the shell makes it possible to increase the efficiency of the burner by organizing an additional zone of heat exchange with fluid jugging through the pipes. Intensive heating of the liquid is carried out not only in the annular gap between the circulation shell 4 and the exhaust pipe 6, but also additionally in pipes 5. The invention The immersion burner containing The spherical chamber is a ignition burner connected by an end to an exhaust branch pipe, on the periphery of which is placed coaxially with the formation of a ring gap, a circulation shell, characterized in that, in order to increase efficiency, it is equipped with a bundle of parallel tubes installed across the exhaust port and a circulation tube. shells are inclined with respect to their longitudinal axis, and the ends of the tubes of the beam are fixed in the wall of the shell. .Sources of information taken into account in the examination I.
