Abstract

Изобретение может быть использовано в топках котлов и промышленных печей дл сжигани газообразного и жидкого топлива и позвол ет повысить экономичность путем улучшени смесеобразовани и увеличени надежности розжига. Циклонна камера 1 снабжена тангенциальным воздуховодом, лопаточным завихрителем 3 и выходным соплом 4. К камере 1 примыкает топливопод- вод щий канал 6 в виде кольцевого коллектора с выходными отверсти ми 13. Канал 6 раз7 , мещен вокруг выходного участка цилиндрической смесительной камеры 8, снабженной газоподвод щим патрубком в виде перфорированной трубки 9 и тангенциальным патрубком подвода воздуха и сообщенной со стабилизатором 7, имеющим свечу 14. Стабилизатор 7 вместе с камерой 8, трубкой 9 и патрубком 12 образуют блок розжига. В камеру 8 через трубку 9 подаетс газ, а через патрубок 12 - воздух. Часть образовавшейс смеси поступает в стабилизатор 7 и воспламен етс свечой 14, что обеспечивает воспламенение оставшейс части смеси. Основное топливо поступает через отверсти 13 канала 6 в циклонную камеру 1, куда через тангенциальный воздуховод подводитс воздух. Смесь основного топлива и воздуха воспламен етс за счет пламени блока розжига, в котором обеспечиваетс надежный розжиг, что позвол ет повысить экономичность работы горелки. 1 з.п.ф-лы, 2 ил.The invention can be used in furnaces of boilers and industrial furnaces for burning gaseous and liquid fuels and allows for greater efficiency by improving formation and ignition reliability. Cyclone chamber 1 is equipped with a tangential air duct, blade swirler 3 and outlet nozzle 4. Chamber 1 is adjacent to fuel supply channel 6 in the form of an annular manifold with outlet openings 13. Channel 6 times7, placed around the outlet section of cylindrical mixing chamber 8 equipped with gas supply a connecting pipe in the form of a perforated tube 9 and a tangential pipe for supplying air and communicating with a stabilizer 7 having a candle 14. The stabilizer 7 together with the chamber 8, the tube 9 and the nozzle 12 form an ignition unit. Gas is supplied to chamber 8 through pipe 9, and air is supplied through pipe 12. A part of the resulting mixture enters the stabilizer 7 and is ignited by the candle 14, which ensures the ignition of the remaining part of the mixture. The main fuel enters through the openings 13 of the channel 6 into the cyclone chamber 1, where air is supplied through the tangential duct. The mixture of main fuel and air is ignited by the flame of the ignition unit, in which reliable ignition is ensured, which makes the burner more economical. 1 hp ff, 2 ill.

Claims

Claim

1. A vortex burner containing a cyclone chamber with a fuel supply channel and an ignition unit located on its end wall, including an ignition stabilizer adjacent to a cylindrical mixing chamber equipped with a gas supply pipe and an air supply channel, characterized in that, in order to increase efficiency by improving mixing and increase the reliability of ignition, the fuel supply channel is made in the form of an annular collector placed around the output section of the mixing chamber, the supply channel ear is located in the inlet portion of the mixing chamber and provided with a tangentially mounted nozzle, and the gas supply pipe is configured as a perforated tube disposed in the cavity of the mixing chamber along its axis.

2. The burner according to claim 1, characterized in that the perforated tube is curved in the form of a spiral with the direction of the turns coinciding with the direction of the air flow formed by the tangential pipe.
