Description
Изобретение относитс к устройствам дл высокотемпературного нагрева газов и может быть применено в металлургических и энергетических процессах.The invention relates to devices for high-temperature heating of gases and can be applied in metallurgical and energy processes.
Известны газонагреватели, содержащие коивективную и радиационную камеры, причем в последней установлены горелки.Known gas heaters containing koivektivnuyu and radiation chambers, with the latter installed burner.
Такое выполнение газонагревателей приводит к высокотемпературной коррозии поверхностей нагрева продуктами горени топлива. Such an embodiment of gas heaters leads to high-temperature corrosion of heating surfaces with combustion products of fuel.
Целью изобретени вл етс повышение надел :ности газопагревател .The aim of the invention is to increase the power of the gas booster.
Это достигаетс тем, что между двум ступен ми нагрева расположена камера дожигани продуктов неполного горени топлива. This is achieved by the fact that the afterburning chamber of products of incomplete combustion of fuel is located between two heating stages.
На чертеже схематически изображен газонагреватель , разрез.The drawing shows schematically the gas heater, the cut.
Газонагреватель содержит радиационную ступень нагрева 1, экранированную трубами 2, снабженную горелками безокислительного пагрева 3, и соединенную с конвективной ступенью 4 камеру дожигани 5 с горелками 6. Холодный воздух в камеру дожигани поступает по каналам 7.The gas heater contains radiation heating stage 1, shielded by pipes 2, equipped with burners for non-oxidizing pagreva 3, and afterburner chamber 5 with burners 6 connected to the convective stage 4. Cold air enters the afterburner chamber through channels 7.
Газонагреватель работает следующим образом .The gas heater works as follows.
окислительную среду продуктов сгорани в радиационной ступени 1.oxidizing environment of combustion products in radiation stage 1.
Продукты неполного сгорани омывают трубы 2 и поступают в камеру дожигани 5. В последней происходит их полное выгорание при добавке холодного воздуха по каналам 7. Полученные дымовые газы направл ютс в конвективную ступень 4, где подогревают среду , например воздух, двигающуюс протииоточно . Подогрета среда поступает в радиационную ступень, где обеспечиваетс ее нагрев до 1000°С и выще.Products of incomplete combustion wash pipes 2 and enter the afterburning chamber 5. In the latter, they burn out completely when cold air is added through channels 7. The resulting flue gases are directed to convective stage 4, where they heat up the medium, for example, air moving oppositely. The heated medium enters the radiation stage, where it is heated to 1000 ° C and higher.
