Abstract
According to one aspect of the present invention, a molten iron manufacturing facility includes: an iron ore reduction furnace, which is used to charge iron ore and introduce a reducing gas to produce reduced iron; a smelting gasifier, which is used to fill coal and charged with reduced iron discharged from the iron ore reduction furnace after being reduced to produce molten iron and reduction gas to be supplied to the iron ore reduction furnace; a gas purification filter type reduction furnace for charging sintered ore and Feed process gas discharged from iron ore reduction furnace after reduction of iron ore to reduce sintered ore; fine dust removal equipment for reduction in gas purification filter type reduction furnace and exhausted a reduced sinter to remove dust; and an oxidation burner for charging the reduced sinter from which the dust has been removed, and then burning the sinter with air to oxidize the reduced sinter.
Description
technical field [0001] The invention relates to molten iron manufacturing equipment and a method for manufacturing molten iron. More specifically, the present invention relates to a molten iron manufacturing equipment and a molten iron manufacturing method using a medium circulation process to treat flue gas. Background technique [0002] Electricity production mainly relies on fossil fuels, especially the use of heat generated by coal combustion for power generation began with the modern steam turbine invented by Parsons in England at the end of the 19th century. [0003] Steam turbines generate heat by burning coal, air, or steam in a boiler reactor, and generate electricity by converting the heat back into steam. However, although steam turbines account for most of the electricity production methods, their efficiency is low, and therefore, power generation using steam turbines is developed as hybrid power generation that removes pollution such as ash (ash) through coal g...
