Description
Известны способы восстановлени железной руды, нагретой до 850-950с, смес ми нефт ного газа и вод ного пара в шахтных печах. Однако применение известных способов сопровождаетс выделением сажистого углерода.Methods are known for reducing iron ore heated to 850-950s with mixtures of petroleum gas and steam in shaft furnaces. However, the application of known methods is accompanied by the release of black carbon.
Предлагаемый способ отличаетс тем, что с целью устранени выделени сажи и более тонного поддержани оптималь-г ной температуры в слое руды, восстановление железа осуществл етс в атмосфере факела горени смеси нефт ного газа с воздухом и вод ным паром.The proposed method is characterized in that in order to eliminate the release of soot and to maintain a more tonne optimum temperature in the ore layer, the iron is reduced in the atmosphere of the flame of the mixture of oil gas with air and water vapor.
Сущность способа заключаетс в том, что восстановление железной руды производитс в шахтной печи при 8ОО1100 С. Руда на восстановление поступает в виде гранул, брикетов иди окатышей .The essence of the method lies in the fact that the reduction of iron ore is carried out in a shaft furnace at 8OO1100 C. The ore is sent to the reduction in the form of pellets, briquettes or pellets.
Восстановление происхо/цит в восстановительной атмосфере факела горени па ровоздухогазовой смеси (нефт ной газ с паром и воздухом) с наиболее выгодным коэффициентом избытка воздуха в пределе 0,05-0,25. Состав паровоздухогазовой смеси дл факела устанавливаетс с расчетом получени бессажисто- го губчатого железа. Дл предупреждени выделени сажистого углерода, в зависимости от состава нефт ного газа, в газовую смесь ввод т 3-54% вод ного пара .Restoration took place in the reducing atmosphere of the flame of the gas-air mixture (oil gas with steam and air) with the most favorable air excess factor in the range of 0.05-0.25. The composition of the vapor-air mixture for the plume is determined with the expectation of production of bespistye sponge iron. To prevent the release of black carbon, depending on the composition of the petroleum gas, 3-54% water vapor is introduced into the gas mixture.
