ANDRITZ PULP & PAPER offers innovative technologies for upgrading existing lime kilns to improve capacity and energy efficiency.  The ANDRITZ LimeFlash technology is also available on new kilns.  ANDRITZ LimeFlash is a kiln feed system that increases capacity of existing kilns by mixing hot flue gasses with the incoming lime mud before the gas enters the feed end housing.  This increases the end temperature without plugging and lime splitting.

Kiln capacity upgrade at minimal investment cost

If the lime kiln is a bottleneck, ANDRITZ LimeFlash may be the perfect solution for increasing kiln capacity at an attractive investment cost.  LimeFlash can be integrated into most existing kilns, even those with external lime mud dryers.  

With LimeFlash, kilns can be operated with higher feed end temperatures without plugging problems.  It is flexible and responsive to changing process conditions and requires minimum maintenance attention.  LimeFlash has demonstrated excellent uptime and availability.

LimeFlash advantages:

  • Increased capacity for existing kilns, even those with external lime mud dryers
  • Increased feed end temperatures without plugging
  • Ease of installation due to an optimized feed head structure
  • No need to elevate lime mud filter to higher level
  • Compact size – smaller building required
