It can be concluded from the obtained results that the speed of thermometer draw dictates the draw of the 9 m layer of stones in the preheating zone, where due to the constant annular shaft kiln's cross-section the speed is constant, and also the lowest due to the maximum kiln cross-section.
The soaking section 83 of the shaft kiln body 8 is provided with heat exchange bodies 92, 93 and 94 in various forms, so that the high-temperature flue gas and the submerged arc furnace raw materials can exchange heat fully and uniformly.
Fuel is fed by these burner lances and evenly distributed across the cross-section of the kiln shaft. The fuel self-ignites together with the preheated combustion …
Lime kilns have been used since antiquity for the production of quicklime (CaO) from calcium carbonate (CaCO 3), which is provided in the form of limestone (Margalha et al., 2008). Oates (1998) describes various kiln designs that have been used over time, including the nowadays common shaft kilns. Parallel-flow regenerative (PFR) …
A PFR (Parallel Flow Regenerative) kiln has two vertical shafts with a connecting crossover-channel. Both shafts work together: one calcines the product, the other …
1 Annular shaft kilns Annular shaft kilns were developed in the 1970s to produce soft-burned lime in a single shaft kiln. To achieve this, a co-current burning zone is estab - …

Figure 1, on the right side, shows a typical tem - perature profile with the green line showing the temperature of the kiln charge, the blue line in the
The annular shaft kiln relies on two rows of burners, one above and one below, to calcine the limestone (calcination temperatures are 1200~1300°C for the upper combustion chamber and 1300~1350°C for the lower combustion chamber). The combustion chambers are located in the middle of the kiln body and are divided into upper and lower layers.
