Lime Kiln Chemistry and Effects on Kiln Operations
نویسنده
چکیده
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 mud and the major chemical reactions involved is critically important in developing preventive measures for the problems.

متن کاملFormation and Techniques for Control of Sulfur Dioxide and Other Sulfur Compounds in Portland Cement Kiln Systems
This report presents the chemical and physical factors governing the generation of sulfur dioxide (SO2), its transformation into other sulfur compounds, and the removal of sulfur oxides within the cement kiln system. Sulfur in cement kilns is derived from both kiln feed and from the kiln fuel. The form of the sulfur dictates the location in the kiln where the SO2 generation takes place. Sulfur ...
متن کاملPrevention of Sulfide Oxidation in Waste Rock using By-products and Industrial Remnants, a Suitability Study
Prevention and mitigation of acid rock drainage from mining are decisive for limiting environmental impact. Five by-products and industrial remnants (lime kiln dust, blast furnace slag, granulated blast furnace slag, cement kiln dust and fly ash) were investigated for their suitability to prevent acidity and metal(loid)s during leaching from highly sulfidic (50wt%, sulfide) waste rock in small ...
