Reconstruction of Lime Kilns
The specialist of Techinservice company have developed and
introduced high-performance equipment and devices for the lime kilns
used for sugar and soda production in the Ukraine and other country.
They include the following components:
- the lime and coke weighing and refining stations;
- the stations for blending lime and coke before their loading
into a kiln;
- the patented loading device with a rotating hopper;
- the station for distributing batch mixture;
- the automated system for controlling lime production
processes;
- the stations for cooling and treating (clean-up) of kiln gas.
Using the loading device with a rotating hopper and the station
for distributing batch mixture allows us practically to exclude the
segregation of batch mixture and provides an uniform distribution of
material in the kiln section extent.
When undertaking the upgrade of your lime kilns, we can guarantee
you as follows:
- a rated output of kiln - up to 14 tons 85% calcium oxide
(CaO)/m2 per day;
- the carbon dioxide (CO2) content in kiln gas - no
less than 35%;
- the coke rate relative to the lime weight - within 6.7÷7.5%;
- the gas temperature when leaving the kiln - no more than
100°C;
- the lime temperature when leaving the kiln - maximum 20°C
higher than ambient air temperature;
- lime slaking time - no more than 5 minutes - after slaking
temperature reaches 80°C;
- the expected (planned) quantity of underburned lime - no more
than 5% relative to the lime weight.
The operation of the kiln is characterized by a very high
flexibility of its regulation within a high capacity range depending
on the total plant capacity, by a high stability of kiln gas
composition, a high lime activity and a low rate of underburned
lime.
When undertaking the upgrade of limekilns, Techinservice company
provides the complete service package and a guarantee, besides, we
undertake also the training of your personnel in servicing,
maintaining and operating of the kiln and carrying out a laboratory
control.
