Lime Kiln
For most operations except for dead burnt dolomite, the burner tip velocities can range between a low of 25 m/s and a high of about 60 m/s. These are significantly lower than the velocities of cement kilns, which operate around 80–100 m/s. The momentum ratio and associated Craya–Curtet parameter is usually lower than 2, which means that the ...

Dolomite thermal behaviour: A short review | Physics and
It has been proposed that the first stage of the decomposition of dolomite in a CO 2 atmosphere occurs by the formation of an unstable magnesite which immediately decomposes to magnesia and calcite (half-burnt dolomite) . The second stage of dolomite decomposition involves the reversible decomposition of calcite to lime, which is highly reactive.
Calcined Dolomite
Notes. Dead-burned dolomite is produced when dolomite is calcined at very high temperatures. It is used both as a refractory product in granular form to repair linings and for making the bricks used in the refractory linings of casting ladles and cement kilns. This refractory work well for ladles because it creates MgO in solution in the slag, which provides an buffering because MgO …

GB2042499A
A refractory material is obtained by pelletising and-dead-burning dolomite and optionally magnesium oxide, or a precursor therefor, in the presence of a stabilising agent which is an oxide or precursor therefor which reacts in the dead-burning with the calcium oxide of the calcined dolomite to produce a product less susceptible to reaction with water.
