Experience and a well proven design are the secrets for a successful lime burning project as several factors influence the choice of lime kiln technology:
Cim-ReVerSy TSR process
The Twin Shaft Regenerative (TSR) kiln family consists of two main groups:
The TSR-Kilns series utilizes the regenerative process for lime calcination. There are two distinguishing characteristics for the TSR-Kilns:
The TSR kilns currently represent the best option for high- and medium-reactivity lime production in terms of:
DIRECT CROSSOVER CHANNEL
RADIAL CROSSOVER CHANNEL
Cim-ReVerSy TSR models
direct cross over channel
radial cross over channel
TurNOx® integrated device
Cimprogetti has selected an innovative SCR process for Parallel Flow Regenerative (PFR) kilns with the specific aim of reducing NOx content in flue gases.
Placed downstream of the kiln, the TurNOx® device modulates parameters without affecting the calcination process in the kiln.
The TurNOx® device complies with the main directives regulating emissions into the atmosphere, in particular, the Best Available Techniques.
TWIN SHAFT REGENERATIVE PROCESS
TSR lime kilns can be fired with:
TSR KILNS DESIGNED TO MEET CUSTOMERS’ PRESENT AND FUTURE REQUIREMENTS ...
ABC® (Advance Burning Concept) is the Cimprogetti vertical single shaft kiln with counter current flow arrangement and is the latest in the evolution of compact design.
Thanks to its particular firing system, the ABC® kiln can produce medium-high to low-reactivity lime with an optimal use of diverse limestone sizes and a variety of fuels.
The ABC® kiln features a cylindrical steel shell and is internally lined with standard-size refractory bricks. The limestone is continuously fed into the sealed loading/distributing device placed on the top of the kiln. Burning takes place in the lower/middle part of the kiln, through a number of burners distributed in several rows around the kiln shell to ensure homogeneous and consistent distribution of the heat over the entire kiln cross section. The lower section of the kiln is equipped with a lime discharge and a lime cooling section by means of air which is introduced from the bottom of the discharge table.
