Hidden Lime Kiln Capacity: Sometimes the fastest route to more lime kiln capacity is not a bigger kiln.
It may be recovering the working diameter already inside the shell. In the chain area, conventional castable lining occupies space. That matters because working internal diameter influences the cross-sectional area available for gas and material movement.
When usable diameter increases, gas velocity can decrease at the same volumetric flow. That can help reduce dust entrainment and pressure related losses, while creating more room for productive kiln operation.
Jammbco’s Econoliners are engineered for the chain area to increase working internal diameter, protect the shell, reduce heat loss, and support a longer lining life.
In a real scenario, one of our customers was able to increase the internal diameter by 12.5% on a 12’ ID kiln.
The number is important, but the engineering around it matters more. Liner thickness, chain layout, temperature zones, draft, feed rate, and downstream capacity must be reviewed as one system.
Before planning a larger capital project, ask yourself a simple question:
Is my kiln using the internal diameter it already has?
