[PDF]2-3 Lime Kiln Chemistry & Effects on Operations
A lime kiln is used to convert lime mud into lime for reuse in the causticizing plant of the kraft recovery process. Many of the problems encountered in lime kiln operations can be related to kiln chemistry, including TRS and SO2 emissions, dusting, ringing and refractory brick thinning. Understanding the composition and thermal behaviour of

Lime is added in the causticizer (13) from a lime kiln (14) and the chemicals are pumped to a clarifier15( ) to allow the solids to settle. Clean cooking chemicals are sent to the digester for re-use, and residuals are washed and sent to the lime kiln to be turned into lime. The naturally brown pulp is made white through a bleaching process (16 ...

Hot lime will drop through holes at the discharge end of the kiln, into the tube coolers where it will preheat the combustion air to 260-370 ºC. The lime will thereby leave the kiln with a temperature of 200-300 ºC instead of ~1100 ºC, reducing the amount of energy that has to be provided to the process (Hough 1985).
[PDF]Manufacture of Lime - How to Manufacture Lime using ...
How to Manufacture Lime. Lime stones are burnt in either clamps or kilns. For small quantity of limestone, burning is done in a clamp. On a clear surface about 5 meters in diameter, layers of broken limestones and fuel are laid to form a heap about 4 meters high. First and the last layers should be .
