Description

Известен способ применени  природного газа с подачей его через фурмы в горн доменной печи.There is a known method of using natural gas with feeding it through tuyeres into a blast furnace hearth.

Однако такой способ приводит к пониженню температуры горна вследствие затрат тепла на р азпожение метана и его подогрев. Установлено, что при вдувании до 5ООО М7ч природного газа температура в горне снижаетс  на 8О100°С , что ухудшает его работу, не позвол ет плавить гор чие марки литейного чугуна, ограничивает увеличение расхода газа,сдерживает рост производительности доменной печи из-за расхода кислорода дуть  на сжигание углерода метана и уменьшени  количества сжигаемого кокса.However, this method leads to a lower temperature of the hearth due to the cost of heat for the dissociation of methane and its heating. It has been established that when blowing natural gas up to ОО M7h, the temperature in the furnace decreases by 8 8100 ° C, which impairs its operation, does not allow hot brands of cast iron to melt, limits the increase in gas consumption, and hinders the growth of blast furnace productivity. burning carbon methane and reducing the amount of coke burned.

Предложенный способ позвол ет осуществл ть конверсию природного газа бе каких-либо капитальных затрат и использовать существующие воздухонегреватели обеспечить вдувание газов-восстановитепей (со и Hg), подогретых до , повысить производительность доменныхThe proposed method allows the conversion of natural gas without any capital costs and the use of existing air heaters to ensure the injection of gas-reducing gases (with and Hg), heated up to, increase the productivity of blast furnace gas.

Сущность способа состоит в следующем .The essence of the method is as follows.

После подогрева воздухонагревател  до температуры выще в поднасадочное пространство при помощи горелки в необходимом соотнощении с воздухом ИЛИ) перегретым паром подают природный газ. При прохождении через нагретую до ук анной температуры насадку воздухонагревател  газ будет подвергатьс  конвертированию при участии кислорода воздуха или вод ных паров поAfter heating the stove to a temperature above, a natural gas is supplied with superheated steam by means of a burner in the required ratio with air OR) with superheated steam. When passing through the air heater nozzle heated to the specified temperature, the gas will be converted with the participation of air oxygen or water vapor.
