(54) ТОПЛИВО-КИСЛОРОДНАЯ ФУРМА(54) FUEL OXYGEN FURM
1one
Изобретение относитс к металлургии и может быть использовано в сталеплавильном производстве.This invention relates to metallurgy and can be used in steelmaking.
Известны газокислородные горелки, которые снабжены камерой сжигани , что позвол ет обрабатывать расплав окислительной и восстановительной смесью и обеспечивает гибкость проведени процесса 1.Gas-oxygen burners are known, which are equipped with an incineration chamber, which allows the melt to be treated with an oxidizing and reducing mixture and provides the flexibility of the process 1.
Наиболее близкой по технической сущности и достигаемому результату к предлагаемой вл етс топливо-кислородна фурма внутреннего смешени дл нагрева шихты и продувки жидкого металла, содержаша водоохлаждаемый корпус, головку с соплами и камеру сжигани со стабилизатором горени топливо-кислородной смеси, соединенную с трубами подвода кислорода, мазута и природного газа 2.The closest in technical essence and the achieved result to the proposed is an oxygen-oxygen tuyere of internal mixing for heating the charge and blowing the liquid metal, containing a water-cooled body, a head with nozzles and a combustion chamber with a combustion stabilizer of the oxygen-oxygen mixture, connected to oxygen supply pipes, fuel oil and natural gas 2.
Однако возможность внутреннего прогара и нестабильность горени при обогащенной или обедненной топливо-кислородной смеси приводит к срыву горени и хлопкам.However, the possibility of internal burnout and the instability of burning with an enriched or depleted fuel-oxygen mixture leads to a breakdown of burning and clapping.
Цель изобретени - повышение стойкости камеры сжигани и стабилизации горени в режимах обогащенной и обедненной топливо-кислородной смеси.The purpose of the invention is to increase the durability of the combustion chamber and stabilize the combustion in the modes of enriched and lean fuel-oxygen mixture.
Поставленна цель достигаетс тем, что стабилизатор горени выполнен в виде нескольких телескопически установленных в камере сжигани труб из жаропрочной стали .The goal is achieved by the fact that the combustion stabilizer is made in the form of several telescopically installed pipes from heat-resistant steel in the combustion chamber.
На чертеже изображена предлагаема фурма, продольный разрез.The drawing shows the proposed tuyere, longitudinal section.
Фурма состоит из водоохлаждаемого корпуса 1, сваренного с головкой 2, сопел, которые соединены сваркой с камерой 3 сжигани . В камере 3 свободно размещены несколько жаровых труб 4, выполненных из The lance consists of a water-cooled body 1, welded to the head 2, nozzles, which are connected by welding to the combustion chamber 3. In the chamber 3 freely placed several flame tubes 4, made of
to жаропрочной стали. Между стенкой камеры и жаровыми трубами выполнен зазор, по которому поступает больща часть кислорода к . В верхнюю жаровую трубу 4 введены трубы 5, 6 и 7 подвода соответственно мазута, природного газа и кислорода.to heat resistant steel. A gap is made between the wall of the chamber and the flame tubes, through which most of the oxygen is supplied to. Into the upper flame tube 4, tubes 5, 6, and 7 are introduced to supply, respectively, fuel oil, natural gas, and oxygen.
Устройство работает следующим образом .The device works as follows.
В камеру 3 сжигани подают кислород, а затем топливо. При малом расходе горючей смеси фронт пламени вт гиваетс в жа20 ровую трубу 4, где сохран етс при любых соотнощени х топлива и окислител , так как необходима дол кислорода дл горени поступает через кольцевые каналы вOxygen is supplied to the combustion chamber 3, and then fuel. With a small consumption of the combustible mixture, the flame front is drawn into the burning pipe 4, where it is maintained at any ratios of fuel and oxidant, since the necessary fraction of oxygen for combustion flows through the annular channels into
