Description
(54) УСТАНОВКА ДЛЯ НАГРЕВА ВОЗДУХА(54) AIR HEATING INSTALLATION
1one
Изобретение относитс к теплообменной технике и может быть использовано в тепловых установках, например, котлах.The invention relates to heat exchange technology and can be used in thermal installations, such as boilers.
Известны установки дл нагрева воздуха , содержащие снабженный дымососом газоход с установленными в нем по крайней мере двум ступен ми воздухоподогревател и размещенный за ним золоуловитель 1.Installations for the heating of air are known, which contain a flue gas pipe fitted with an exhaust fan with at least two stages of an air preheater installed therein and a ash collector 1 arranged behind it.
Недостатком указанной установки при сжигании серосодержащего топлива, например мазута, вл етс низка теплова эффективность и ненадежна защита золоуловител от низкотемпературной коррозии.The disadvantage of this installation when burning sulfur-containing fuel, such as fuel oil, is the low thermal efficiency and unreliable protection of the ash collector from low-temperature corrosion.
Наиболее близкой к предлагаемой вл етс установка дл нагрева воздуха, содержаща снабженный дьщососом газоход с установленными в нем по крайней мере двум ступен ми воздухоподогревател , между которыйи размещен золоуловитель 2.Closest to the present invention is an installation for air heating, comprising a gas flue gas pipe provided with at least two stages of an air preheater installed, between which the ash collector 2 is located.
В известной установке золоуловитель защищен от коррозии, но ее недостатком вл етс сравнительно невысока эксплуатационна надежность, св занна с коррозией второй ступени воздухоподогревател по ходу газов и золовым заносом этой ступени, аIn the known installation, the ash collector is protected from corrosion, but its disadvantage is the relatively low operational reliability associated with the corrosion of the second stage of the air preheater along the gases and the ash drift of this stage, and
также коррозии и золовому заносу дымососа и газохода перед ним.as well as corrosion and ash drift of the smoke exhauster and gas duct in front of it.
Цель изобретени - повышение эксплуатационной надежности.The purpose of the invention is to increase operational reliability.
Дл достижени поставленной цели дымосос включен в газоход между золоуловителем и второй ступенью воздухоподогревател , а перед дымососом дополнительно установлен аппарат дл ввода присадок в дымовые газы.To achieve this goal, the exhaust fan is connected to the gas duct between the ash collector and the second stage of the air preheater, and an apparatus for introducing additives into the flue gases is additionally installed in front of the exhaust fan.
Q Кроме того, втора ступень воздухоподогревател выполнена из стекл нных или тепловых труб.Q In addition, the second stage of the air preheater is made of glass or heat pipes.
На чертеже схематически показана предлагаема установка.The drawing schematically shows the proposed installation.
Установка содержит снабженный дымо15 сосом 1 газоход 2 с установленными в нем ступен ми 3 и 4 воздухоподогревател , между которыми размещен золоуловитель 5, причем дымосос 1 включен между золоуловителем 5 и второй ступенью 4 воздухоподогревател по ходу газов, а перед дымососом установлен аппарат 6 дл ввода присадок в дымовые газы. Втора ступень 4 воздухоподогревател изготовлена из стекл нных или тепловых труб, а газоход 2 после нее подключен к дымовой трубе 7.The installation contains a flue 2 supplied with a smoke exhauster 1 with steps 3 and 4 of an air preheater installed between it, between which a dust collector 5 is placed, with the exhaust fan 1 connected between the dust collector 5 and the second step 4 of the preheater along the gases, and in front of the exhauster an apparatus 6 for injecting additives is installed into flue gases. The second stage 4 of the air preheater is made of glass or heat pipes, and the gas duct 2 after it is connected to the chimney 7.
