Abstract Iron oxide pellets are currently one of the main feedstocks in iron-making processes, and increasing over the years. They are mostly produced in moving-grate induration furnaces. Several mathematical models describing the pellet induration process have been published over the last 50 years. Despite being a topic of research for a long period, a relative small amount of journal papers ...
A study was carried out by CanmetENERGY and ArcelorMittal Mines Canada (AMMC) to investigate the feasibility of reducing fuel consumption and greenhouse gas (GHG) emissions in an Outotec (previously Dravo-Lurgi) traveling straight grate induration furnace using flue gas recirculation.
Grate-Kiln iron ore pelletizing system Principles of operation • Traveling grate - Pellets are dried and partially indurated through multiple cross flow process zones: updraft drying, downdraft drying, tempered preheat, and preheat, strengthening pellets for processing in rotary kiln - Average bed depth 180 mm; no hearth layer required as in ...
During induration, the green pellets are distributed evenly across the traveling grate and then hardened in a furnace where they pass through updraft drying, ... Diagram of a travelling grate furnace fed by spreader-stokers (Detroit Stoker Company 1998) from publication: European .
TRAVELLING GRATE PROCESS Travelling grate machine used for induration of green pellets resembles the well-known sintering machine of Dwight Lloyd design. Travelling grate machine is having completely closed hood with many interconnected thermal zones for recirculation of [tpvrdd gas leading to maximum heat recovery.
measured by ultrasound probes to ensure the proper speed of the travelling grate. 2.3 Indurating Furnace The induration furnace is of circular design that allows the furnace hood to cover more than twice as many pallet cars compared to a straight-type induration furnace. A far more efficient utilization of installed equipment is thus achieved.
Travelling Gate Technology: Travelling grate technology is the proven and widely used induration furnace technology Grate Kiln Technology Circular Pelletizing Technology (introduced by Voestalpine/ Siemens) – The world's most compact pelletizing plant facilitates integration at the mine or …
In the present pelletizing apparatus, the induration of iron ore concentrate pellets is achieved in a tunnel furnace heated by plasma torches, wherein the generation of by the conventional iron ore pelletizing processes is reduced by using electricity powered plasma torches instead of burning natural gas, heavy oil or pulverized coal in burners, thereby reducing considerably industrial ...

The test was the pioneer with Biomass in Samarco, occurred in the period of January 27 to July 21 of 2014. It was performed a detailed evaluation of the engineering of this system and its impact on the Traveling Grate Kiln.
Multiobjective optimization of an industrial straight grate iron ore induration process is carried out in this study using an evolutionary algorithm. A simultaneous maximization of throughput and pellet quality indices like cold compression strength (CCS) and Tumbler index (TI) is adopted for this purpose, which leads to an improved optimal control of the induration process as compared to the ...
The first principle induration model was validated and tested using data published in the literature by Thurlby et al. (1979) for an induration furnace of Dravo–Lurgi design with 400 m 2 grate area traveling across 60 wind-boxes each 2 m long.

In induration section, the indurating hood is the main part of a pelletizing plant for iron-ore fines. It serves for drying, heating and cooling of the pellets. The Indurating hood is installed above the travelling grate.
In the travelling straight grate process, the second source of heat comes from fossil fuel injected through burners located in burner ports on both sides of the furnace. Fuel could be in different forms but the most common ones are liquid fuel (light oil or more frequently heavy fuel oil) or gaseous fuel (natural gas or CO gas coming from other ...
