Origin of the project
The LADRILLERA SANTA FE (Bogotá, Colombia) is the ceramics group with the largest production in all of Latin America. With 6 kilns distributed over two plants less than 5 kilometres from each other in the outskirts of the Colombian capital, the group sells more than 2500 tonnes of bricks a day.
In 2009 the group already tried firing using coal in a few of its kilns, but unfortunately the results weren’t satisfactory enough to warrant extending the use of this fuel to all of them. The coal in Colombia is of extraordinary quality, often about 7000 Kcal/kg (30,000 Kj/kg), with a moderate presence of ash (<12%), and a high content of volatile matter (>30%). Furthermore, it is very economical, especially compared to the natural gas which LADRILLERA SANTA FE used to consume, which was becoming increasingly more expensive at the time when they contacted BERALMAR to study the use of coal facilities for all the group's kilns.
Execution of the project
Within two years, BERALMAR coal combustion facilities were installed in all LADRILLERA SANTA FE kilns.
Since all the kilns are distributed over two plants, the implemented solution involved supplying BERALMAR’s centralized grinding stations with rotary mills to feed dry and micronized coal of less than 100 microns to the new MICROMATIC facilities formed by silos equipped with all the anti-explosive safety measures. From these, separate pneumatic circuits—one for each kiln—distributed and dosed the coal according to the temperature set points.
With BERALMAR’s technology and experience and the high quality of Colombian coal, the result was a huge success.
