Изобретение относитс к области черной металлургии, в частности к способам домен ной плавки с/ применением сомбинированного дуть .The invention relates to the field of ferrous metallurgy, in particular, to the methods of domain smelting with / using a combined blow.

Однако при сатурации жидкого топлива Ю восстановительными газореагентами в цвеТ| ном способе, возникает опасность преждев. ременного загорани топлива. Кроме того, использование окислительных газореагентов приводит к быстрой электрокимической корроч зии топливной арматуры и ёмк(зстей.fuel before its introduction into the blast furnace by saturation (gas saturation) of the liquid fuel with predominantly oxidizing components (air, oxygen). . However, with the saturation of liquid fuel, Yu with reducing gas reagents in the color of | In the conventional method, there is a danger of premature. belt light up the fuel. In addition, the use of oxidizing gas reagents leads to a rapid electro-acoustic corrosion of fuel fittings and containers.
Цель изобретени - ; интенсифицировать. процесс горени ,повнсить полноту сгорани топлива и увеличить удельный расход его.The purpose of the invention is; intensify. the combustion process, to increase the completeness of the combustion of fuel and increase its specific consumption.
Сущность предлагаемого способа заклю- 20 чаетс в том, что жидкое топливо, (например мазут, нефть, каменноугольна смола) перед вводом в фурменный прибор подвергают са турации (насыщению газами) под давлением газа от 0,5 до 2О ати и со степенью насы 25The essence of the proposed method lies in the fact that liquid fuel (for example, fuel oil, oil, coal tar) before entering into the tuyere apparatus is subjected to saturation (saturation with gases) under a gas pressure of 0.5 to 2 O mp and 25% sat.
щени газом от 0,3 до 15% в зависимости от вида топлива, его расхода, температуры и давлени . Предусматриваетс сагурацн, газообразиым , топпгшом восстановителем, в качестве которсго используетс колошни, ковый газ доменных печей, природный и коХ- совы и газы.Gas from 0.3 to 15% depending on the type of fuel, its consumption, temperature and pressure. Sagurats, a gaseous, toppings reducing agent is envisaged, using kolosni, bovine blast furnace gas, natural gas and natural gas and coke ovens.
Насыщение газом осуществл етс в cetm тураторах или в смесителе инжекционного типа, а также путем барботажа газа черва слой жидкого топл1гоа.Gas saturation is carried out in cetm turators or in an injection-type mixer, as well as by sparging a gas to the worm of a liquid fuel layer.
Благодар насыщении} жидкого топлива газом улучшаетс перемещивание топлива с потоком дуть , ускор ютс процессы газифим кации топлива и его горени , повышаетс полнота сгорани жидкого топлива и эффектив ность использовани его в доменной плавке, Применение данного способа позволит увели чить расход лащкого топл1юа на 100-200 кг/т чугуна без ухудшени коэффициента замены кокса жидким топливом.Due to the saturation} of liquid fuel with gas, the movement of fuel with the flow of blowing is accelerated, the gas-hydrogenation and combustion processes of the fuel are accelerated, the full combustion of the liquid fuel and the efficiency of its use in blast-furnace smelting increase. kg / t of pig iron without degrading the rate of coke replacement by liquid fuel.
