1996-1-1 · The calcination behaviour of limestone particles (6–90 μm) under furnace injection conditions (1073–1673 K) was determined. Scanning electron microscopic analysis of partially calcined particles revealed that calcination occurred over the total (internal and external) surface area with different calcination rates at different locations.

Modeling of Limestone Calcination Using Joule Heating

The limestone calcination reaction is endothermic and will proceed only if the partial pressure of CO 2 in the gas above the solid surface is less than the decomposition pressure of the CaCO 3. As the reaction is endothermic, the conventional process for calcination uses coal firing in rotary kiln with limestone feed to get the desired temperatures.

1992-4-1 · Limestone calcination is a shrinking-core process, in which the reaction proceeds at an internal interface between a residual, unreacted limestone core, and an outer shell of calcined lime. The rate of calcination is proportional to the carbon dioxide concentration driving force between the reaction interface and the bulk atmosphere surrounding the particle.
