20140252696 | METHOD OF OPERATING REGENERATIVE HEATERS IN BLAST FURNACE PLANT - In a blast furnace plant, at least three regenerative heaters are cyclically operated on blast and on gas: while a regenerative heater is operated on gas, hot flue gas is produced and caused to flow through the regenerative heater so as to heat the heat storage elements; and while a regenerative heater is operated on blast, process gas, i.e. a CO-rich fraction of the top gas, is blown through the regenerative heater so that the process gas takes up heat from the heat storage elements. During, such that during a changeover of a regenerative heater from on-blast to on-gas operation, the regenerative heater is purged from process gas using flue gas collected after having flown through at least one of the regenerative heaters. | 09-11-2014 |
