The kiln burner technology has undergone substantial improvements and burners with multiple channels for air and fuel flow are being universally used. The multiple channels provide flexibility in changing the flame shape and its intensity by the control of air flow in the axial and swirl channels, air velocities and adjustment of burner position.
Serious deposits in the grate-kiln plant for iron ore pellet production can decline pellets quality and reduce production efficiency. The initial stage of deposit formation is crucial for adhesion and growth of deposit on refractories in the kiln.

Slag formation in the grate-kiln process is a major problem for iron-ore pellet producers. It is therefore important to understand the slag formation mechanism in the grate-kiln production plant.
For the production of iron ore pellet, a common technology is the grate–kiln process. This process combines a travelling grate and a rotary kiln in which the pellets are dried, oxidized and sintered. A description of a typical grate–kiln pelletization plant can be found in the work by Jonsson et al. [1].
The kiln burner utilizes cooler off gas to heat material bed to nominal of 1200-1340 °C completing the slag bonding and mineral bridging to form pellets. In the Cooler, pellets …
High-efficiency burner meeting the highest environmental standards and capable of reducing fuel consumption; Green pellet online size control for more uniform pellets, which increases the efficiency of the process gas …
1 Suitability of cement kilns for the combustion of secondary fuels. Compared to other high energy-intensive production processes of cement clinker burning process allows a relatively high potential to use secondary fuels [1]. This is due to the robustness of the clinker burning process and in its principal layout as a countercurrent process.
The burner system is an important and integral component of a rotary kiln system that optimizes the fuel combustion to release heat in the kiln. With more than 70 years of experience, we can help you improve your kiln's reliability, sustainability, availability and …
Pellet plant" based on Travelling grate (TG) process will meet the above demand. Two major process routes i.e. Travelling Grate (TG) & Grate Kiln (GK) process are adopted ... rotary kiln. Burners Large number of burners along the length of induration furnace.
And the results lay a solid foundation for online control. Establishment of kiln process control expert system was presented, with maximum temperature of pellet and gas temperature at the feed end as control cores, and interval estimate as control strategy. Software was developed and put into application in a pellet plant.
Our iron ore pelletizing systems combine the best features of both technologies to provide the most modern plant and to produce pellets at the lowest cost and highest quality. ... Both straight grates and grate kilns dry the pellets out in a drying section, then bring the pellets up to a temperature of about 800-900 °C in a preheat zone, then ...
The pellets entering from the raised end of the kiln flow down with a tumbling motion due to the rotation of the kiln and its slope, so that the complicated phenomena of flow, combustion, heat transfer, and physicochemical reaction etc. take place. The magnetite oxidation (Eq.
Fuels used in burning a rotary kiln are classified into three groups: solid, liquid, and gaseous fuels. ... Several kilns can be fired from this single grinding plant and coal rates, to the kiln, can be adjusted instantaneously by the operator. ... Net heating values can be calculated from the results of the calorimeter test by subtracting the ...
The First Grate Kiln System pellet plant was installed in 1960. ... Another part of the Grate Kiln System process Flexibility is because there is only one burner. The Kiln burner can use liquid ...
Pellet firing is achieved by numerous burners arranged throughout the preheating and firing zones. Ambient air is blown counter-current to the flow of pellets through
Deposit formation in the coal-fired rotary kiln is frequently found in the production of fluxed iron ore pellets by the grate-kiln process and affects normal production. In this paper, the effects of pellet basicity (CaO/SiO[2] mass …
These stages consist of (i) raw material preparation, (ii) formation of green balls or pellets, (iii) induration of the pellets, and (iv) cooling, storage and transport of pellets. Raw material preparation – During the process for pelletization iron ore concentrate from iron ore beneficiation plant is dried and heated to around 120 deg C.
