Calcination of pulverized limestone particles under

01/01/1996· 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 A model consistent with experimental rate data
