Gas Fired Iron Ore Pelletizing Kiln. The iron oxide pelletizing industry is very energy intensive and relies heavily on natural gas to fire pellet-indurating furnaces. Approximately 75 million long tons of iron oxide pellets are produced in the United States each year, requiring a fuel input of about 55 billion ft³ of natural gas.
These plants use iron ore pellets in the rotary kiln. Raw material mix consisting of iron ore, dolomite and non-coking coal is fed at the one end of the rotary kiln and is heated by coal burners to produce DRI. ... The hot reduced material from the kiln then passes to the rotary cooler though transfer chute for cooling. The cooler is also ...

Burner Pipes. Burner pipes are used to convey and introduce fuels into the pyroprocess. Fuel is conveyed pneumatically through the inside of the burner pipe and blown into the kiln, where it ignites, providing the necessary heat for the process. The process environment is subject to thermal shock (the result of a sudden loss of flame), alkali ...
This paper summarizes more than a decade of systematic studies of the flow field in an iron ore pelletizing rotary kiln using computational fluid dynamics (CFD) on simplified models of a real kiln. Physical, laser-based experiments have been performed to validate part of the numerical results. The objective is a better understanding of the kiln …
The global annual production of steel is approximately 2 billion tons, accounting for 8 % of the world's energy demand and 7 % of carbon dioxide (CO 2) emissions in the energy sector.Coal-based direct reduced iron (DRI) reduces CO 2 emissions by 38 % compared with traditional blast furnace–basic oxygen furnace (BF …

They enter the rotary kilns through a feed chute and are initially pre-heated with the liberation of heat from the volatiles from the coal in the first 1/3rd of the kiln. The reduction process begins after this where the iron oxides are reduced to metallic iron. The following chemical reactions take place inside the kiln. C + O2 = CO2 CO2 + C = 2CO
