Abstract

Горелката ще намери приложение в металургията, по-спецално в топилните пещи, изискващи висока температура на загряване. С нея се постига висока стабилност на пламъка за широк диапазон на промяна на работните условия. Горелката съдържа смесителна камера (2) с присъединени към нея тръбопроводи за газ (18) и окислител (20), както и цилиндрична горивна камера (4), които са свързани последователно, а между тях е фиксирана пламъчна камера (3), чийто изход е с кръгло напречно сечение, а към нея е монтирано запалващо устройство (7). Горивната камера (4) е с вътрешен диаметър d и ефективна дължина l , а изходът на пламъчната камера (3) е с диаметър d . Горивната камера (4) е разположена в огнеупорен муфел (23) с габаритна дължина l . Отношението d /d е между 1,35 и 1,70, отношението l /d е между 1,2 и 3,7. Отношението l /l е между 1,2 и 2,0.The burner will find application in metallurgy, more specifically in melting furnaces requiring a high heating temperature. It achieves high flame stability over a wide range of changing operating conditions. The burner contains a mixing chamber (2) with gas pipelines (18) and oxidizer (20) connected to it, as well as a cylindrical combustion chamber (4), which are connected in series, and between them is a fixed flame chamber (3), whose outlet has a round cross-section, and an ignition device (7) is mounted to it. The combustion chamber (4) has an internal diameter d and an effective length l , and the outlet of the flame chamber (3) has a diameter d . The combustion chamber (4) is located in a refractory muffle (23) with overall length l. The d / d ratio is between 1.35 and 1.70, the l / d ratio is between 1.2 and 3.7. The ratio l /l is between 1.2 and 2.0.
