Origin of the project
In 2001 CERÁMICA SAMPEDRO in Lardero (La Rioja) asked BERALMAR to build a new tunnel kiln, replacing the old curved vault tunnel kiln. The target production for the new kilm was 240 tonnes/day, increasing the quality of the material and lowering the thermal consumption.
Because the new kiln was to be built in the same place as the old one, the daunting challenge was to proceed with the demolition of the old kiln and the construction of the new kiln in the shortest possible time, in a context of high demand for building materials in which the market absorbed all production.
Execution of the project
Given the need for fast execution of the project, BERALMAR presented an ambitious approach to the customer which involved constructing the kiln in only 12 weeks.
The FORNTHERMIC kiln—98.2 metres long, 3.38-metre interior width and 1.55-metre useful height—was built by the deadline, although the customer later confessed that they were skeptical.
The tunnel kiln was fitted with a natural gas combustion installation, high and low temperature heat recovery, lateral air injection in the preheating zone (an alternative still seldom used at the time compared with traditional recirculating fans) and MICROBER automatic firing control.
