Изобретение относитс к области металлургии и предназначено дл нагрева шлаковой ванны, тепло которой используетс дл обогрева головной части крупных кузнечных слИтков .The invention relates to the field of metallurgy and is intended to heat a slag bath, the heat of which is used to heat the head of large forging layers.
Известны туннельные газокислородные горелки, состо щие из концентрически расположенных труб дл подачи топлива и кислорода и футерованной камеры сгорани .Tunnel gas-oxygen burners are known, consisting of concentrically arranged pipes for supplying fuel and oxygen and a lined combustion chamber.
Однако известные горелки требуют специального охлаждени камеры сгорани , так как в ней при горении температура может доходить до 3000°С и выше.However, the known burners require special cooling of the combustion chamber, since the temperature in it can reach 3000 ° C and higher.
Дл обеспечени устойчивой работы при погружении ее в шлаковую (ванну предлагаема горелка имеет концентрическую испарительную полость, расположенную вокруг внешней стенки камеры сгорани и соединенную с ней и с трубопрОВОдом подачи жидкого кислорода каналами.To ensure stable operation when immersed in the slag (bath, the proposed burner has a concentric evaporative cavity located around the outer wall of the combustion chamber and connected to it and to the piping of the liquid oxygen supply channels.
Дл улучшени охлаждени стенки камеры сгорани испорительна полость имеет сечение , увеличиваюш,еес от входных отверстий к периферии.In order to improve the cooling of the wall of the combustion chamber, the effector cavity has a cross section that increases from the inlets to the periphery.
Дл увеличени стойкости футеровки камеры сгорани суммарна площадь сечений каналов уменьшаетс от входных отверстий к периферии .In order to increase the lining resistance of the combustion chamber, the total area of the channel sections is reduced from the inlets to the periphery.
На чертеже представлена описываема горелка, состо ща из двух конценцрично расноложенных труб / и 2, наружного 3 и внутренного 4 кожухов, огнестойкой футеровки 5 камеры сгорани , крышки 6, крышки 7 с отверсти ми 8, сменного сопла 9, трубопровода 10 дл подачи жидкого кислорода, трубопровода 11 дл подачи газообразного топлива, концентрической испарительной полости 72 дл жидкого кислорода, отверстий 13 дл перехода кислорода в полость 14The drawing shows the described burner consisting of two concentrically disposed pipes / and 2, outer 3 and inner 4 casings, fire-resistant lining 5 of the combustion chamber, cover 6, cover 7 with holes 8, replaceable nozzle 9, pipe 10 for supplying liquid oxygen , pipe 11 for supplying gaseous fuel, concentric evaporating cavity 72 for liquid oxygen, openings 13 for oxygen to pass into cavity 14
футерованной камеры сгорани . Горелку устанавливают над шлаковой ванной. Включают подачу небольшого количества газообразного топлива, которое поджигают посторонним источником тепла. Затем в горелкуlined combustion chamber. The burner is installed above the slag bath. Include the supply of a small amount of gaseous fuel, which is ignited by an external heat source. Then into the burner
подают 1кислород. Футеровка 5 и внутренний кожух 4 нагреваютс до температуры, при которой происходит самовоспламенение смеси. После этого газообразный кислород постепенно замен ют жидким кислородом. Жидкийserves 1 oxygen. The lining 5 and the inner casing 4 are heated to the temperature at which the self-ignition of the mixture occurs. After that, gaseous oxygen is gradually replaced by liquid oxygen. Liquid
кислород, пройд отверсти 5 в крышке 7, попадает в полость 12. Охлажда кожухи 3 и 4, кислород из жидкого переходит в газообразное состо ние ичерез отверсти 13 проникает в полость 14 камеры сгорани . Здесь он расходуетс на окисление углеводородного топлива .the oxygen passed through the openings 5 in the cover 7 enters the cavity 12. The cooling of the covers 3 and 4, the oxygen from the liquid enters the gaseous state and through the openings 13 penetrates the cavity 14 of the combustion chamber. Here it is used to oxidize hydrocarbon fuels.
После установлени стабильного горени топливо-кислородной смеси горелку погружают в шлаковый расплав и корректируютAfter establishing a stable combustion of the fuel-oxygen mixture, the burner is immersed in the slag melt and adjusted
