ContactOct 22, 2015 With the relatively low cost of natural gas NG in North America, combining natural gas injection with PCI has become one method of significantly reducing coke use in blast furnace operation. Typically, coinjection of natural gas utilizes one of two methods, a dual lance design one NG, one PC or a tuyere port for NG injection.
ContactInjecting pulverized coal and natural gas into blast furnaces for ironmaking decreases metallurgical coke requirements, providing a net decrease in the CO 2emissions and in many cases, operating costs associ- ated with iron production.
Contact2021-6-16 Blast Furnace Gas Blast furnace gas is a by-product of blast furnaces where iron ore is reduced with coke into metallic (pig) iron. The gas has a very low heating value of around 0.9kWh/Nm 3,which on its own is typically not high enough for combustion in a gas engine.
Contact2013-7-18 Abstract. Abstract. The operation of blast furnaces using natural gas and oxygen enriched blast (composite blast technology) is being used in many iron and steel companies to reduce the consumption of coke per unit weight of hot metal.
Contact2019-2-22 In blast furnace ironmaking, coke can be partially replaced by injected natural gas. Tuyère injection of cold natural gas is commonly practiced in North America. In this work, limits to the tuyère injection rate have been quantified with mass and energy balances. The fundamental origin of the limits is the endothermicity of methane injection.

Problems and Prospects of Low-Coke Blast-Furnace Technology removal of CO 2 from the top gas and 100% oxygen blast developed by Tulachermet (Puhov, Stepin, & Sceytlin a.o., 1991); • Injection of 300-400 kg pulverized coal/thm (PCI-technology).
Contact2018-1-19 Blast Furnace Natural Gas Injection Lower natural gas prices lead to increased injection of natural gas in blast furnaces, In 2013, all but 1 of 29 of NAFTA blast furnaces are injecting gas while 45 % are co injecting with gas and PCI, while one coal injection system (to serve 2 BF’s) remains idle
Contact2019-10-6 The high-temperature CO2 gas reacts with the carbon in the coke to form CO, and the CO further reduces the iron ore to form molten iron. Carbon supply: The carbon content of pig iron is about 4%, all from blast furnace coke, accounting for 7%-9% of coke carbon content. Heating: The combustion of coke
