Description
Przedmiotem wynalazku jest sposób zmniejszenia zużycia koksu w wielkim piecu przez zastosowanie tlenu technicznego w nagrzewnicach dmuchu.The present invention relates to a method of reducing coke consumption in a blast furnace by using technical oxygen in blast heaters.
Obecnie wysokie temperatury podgrzania dmuchu wielkopiecowego w nagrzewnicach wielkopiecowych uzyskuj e się za pomocą opalania nagrzewnic wielkopiecowych mieszanką gazu wielkopiecowego i gazu bogatego (gazu koksowniczego lub gazu ziemnego).Currently, high temperatures of heating the blast furnace blast in blast furnace heaters are achieved by firing blast furnace heaters with a mixture of blast furnace gas and rich gas (coke oven gas or natural gas).
Sposób według wynalazku polega na tym, że paliwo bogate używane do wzbogacania gazu wielkopiecowego w nagrzewnicach wielkopiecowych zastępuje się w całości lub w części przez dodatek tlenu technicznego do powietrza spalania, a zwolnione z nagrzewnic paliwo bogate wprowadza się do dysz wielkiego pieca jako paliwo zastępcze w procesie wielkopiecowym.The method according to the invention consists in that the rich fuel used to enrich the blast furnace gas in blast furnace heaters is replaced in whole or in part by the addition of technical oxygen to the combustion air, and the rich fuel released from the heaters is introduced into the nozzles of the blast furnace as a substitute fuel in the process. blast furnace.
Istota wynalazku polega na zastąpieniu paliwa bogatego (gazu koksowniczego lub gazu ziemnego) w całości lub w części przez dodatek tlenu technicznego do powietrza spalania nagrzewnic wielkopiecowych zachowując na tym samym poziomie temperaturę dmuchu wielkopiecowego. Zwolnione z nagrzewnic wielkopiecowych paliwo bogate zostaje wprowadzone do strefy dysz w wielkim piecu jako paliwo zastępcze. Na skutek efektu zastępowania uzyskuje się zmniejszenie zużycia koksu w wielkim piecu.The essence of the invention consists in replacing the rich fuel (coke oven gas or natural gas) in whole or in part by adding technical oxygen to the combustion air of blast furnace heaters, keeping the temperature of the blast furnace at the same level. The rich fuel released from the blast furnace heaters is introduced into the nozzle zone of the blast furnace as a substitute fuel. The replacement effect reduces the coke consumption in the blast furnace.
Rozwiązanie techniczne wynalazku polega na tym, że pozostający do dyspozycji tlen techniczny wprowadza się za pośrednictwem stacji redukcyjnej do przewodu powietrza spalania nagrzewnic wielkopiecowych. Impuls o wielkości strumienia tlenu technicznego i impuls o aktualnej wartości opałowej gazu wielkopiecowego służą do sterowania ilością zwolnionego gazu bogatego, który jest kierowany do instalacji wdmuchiwania paliw zastępczych do strefy dysz w wielkim piecu.The technical solution of the invention consists in the fact that the available technical oxygen is introduced through a reduction station into the combustion air conduit of blast furnace heaters. The pulse of the technical oxygen stream size and the pulse of the current calorific value of the blast furnace gas are used to control the amount of released rich gas, which is directed to the installation for blowing alternative fuels into the nozzle zone of the blast furnace.
Wynalazek ma szczególne uzasadnienie do praktycznego zastosowania w warunkach istnienia nadmiarowych ilości tlenu technicznego w dwuetapowej technologii produkcji stali wielki piec - konwertor.The invention is particularly justified for practical application in conditions of existence of excess amounts of technical oxygen in the two-stage steel production technology - blast furnace - converter.
