The TSR-Kilns series utilizes the regenerative process for lime calcination. There are two distinguishing characteristics for the TSR-Kilns:

  • the parallel flow of hot gases and stone in the burning zone, which allows a mild burning of the limestone without over-burning, and
  • the regenerative preheating of all combustion air, using the limestone contained in the preheating zone of the kiln (in the non-burning shaft) as a heat accumulator.

The TSR kilns currently represent the best option for high- and medium-reactivity lime production in terms of:

  • lower fuel consumption,
  • lower maintenance costs,
  • lower emission rates,
  • higher quality lime.
