Изобретение относитс к черной металлургии , в частности к нроизводству стали в мартеновских печах с отоплением их реформированным природным газом.The invention relates to ferrous metallurgy, in particular, to the production of steel in open-hearth furnaces with heating with reformed natural gas.
Известен способ реформировайи нриродного газа дл отоплени мартеновских печей, включающий подачу природного газа и гор чего воздуха и отвод воздушно-газовой смеси во взаимно перпендикул рных направлени х. Однако низкие температуры развити факела неполного горени ограничивают возможность разложени метана в зоне ввода природного газа и тем самым снижают интенсивность реформировани и удлин ют зону реформации, что требует увеличени объема реформационной камеры.There is a known method of reforming natural gas for heating open-hearth furnaces, which includes the supply of natural gas and hot air and the removal of the air-gas mixture in mutually perpendicular directions. However, the low temperatures of the development of the incomplete combustion plume limit the possibility of methane decomposition in the natural gas injection zone and thereby reduce the intensity of reforming and lengthen the reformation zone, which requires an increase in the volume of the reformation chamber.
С целью интенсификации процесса реформировани предложено природный газ подавать в реформатор двум нротивоноложно направленными параллельными в вертикальной плоскости стру ми. Это приводит к организации в реформаторе рециркул ционных газовых потоков , что повышает температуру в зоне ввода природного газа и интенсифицирует процесс разложени метана.In order to intensify the reforming process, it was proposed to supply natural gas to the reformer with two oppositely directed jets parallel in the vertical plane. This leads to the organization of recycle gas flows in the reformer, which raises the temperature in the zone of the input of natural gas and intensifies the decomposition of methane.
Способ осуш;ествл ют следуюш,им образом. Природный газ подвод т в реформатор при помощи двух горелок, размещенных, например , на противоположных стенках реформационной камеры. Перпендикул рно к направлению подачи природного газа подают воздух, например, из вертикального канала мартеновской печи. Образующийс газовый поток под вли нием двух противоположно направленных струй природного газа перед тем, как поступить в трубопровод, соедин ющий реформадионную -камеру с головкой мартеновской печи , рециркулирует в реформационной камере, за счет чего удлин етс путь реформировани газа и повышаетс в камере температура.The method is dried; it follows the same way. Natural gas is supplied to the reformer by means of two burners placed, for example, on opposite walls of the reformation chamber. Perpendicular to the flow direction of natural gas, air is supplied, for example, from the vertical channel of the open-hearth furnace. The resulting gas flow, under the influence of two oppositely directed natural gas jets, before it enters the pipeline connecting the reforming-chamber to the head of the open-hearth furnace, is recirculated to the reforming chamber, thereby lengthening the gas reforming path and the temperature in the chamber.
Количество реформированного газа составл ет 45-50% от общего расхода природного газа. Мазут может быть введен как в верхнюю горелку головки мартеновской печи, так и в обе горелки реформатора. Степень рециркул ции устанавливаетс опытным путем и должна иметь кратность рециркул ции не менее двухтрех .The amount of reformed gas is 45-50% of the total consumption of natural gas. Fuel oil can be introduced both in the upper burner of the head of the open-hearth furnace and in both burners of the reformer. The recycle rate is established empirically and must have a recycle rate of at least two-three.
Реформирование природного газа в рециркул ционном потоке, создаваемом двум противоположно направленными стру ми топлина , позвол ет уменьшить удельный объем реформатора до 0,2-0,5 мз на 100 мз/час реформированного газа, что позволит уменьшить затраты на сооружение реформаторов и более компактно размещать их на головках металлургических печей.Reforming natural gas in a recycle stream created by two oppositely directed jets of toplin reduces the specific volume of the reformer to 0.2–0.5 m3 per 100 m3 / h of reformed gas, which will reduce the cost of building reformers and more compactly accommodate them on the heads of metallurgical furnaces.
