New Heat Recovery Systems Used in Spanish Tile Production Achieve Energy Savings of 20%

ENDESA, one of the main energy suppliers of Spain, has designed a heat recovery system for Tile of Spain manufacturers that reduces energy bills and CO2 emissions by up to 20%. The new heat recovery system reuses the thermal energy that is lost in the kilns during the firing process, resulting in potential annual savings of up to 400,000 Euros per installation.

Azulev was the first Tile of Spain company to install the new heat recovery system.

The Spanish ceramic industry has spent the last few years actively looking to decrease energy consumption during the production of ceramic tiles, while production is increasing. The new heat recovery system developed by ENDESA works by recovering the heat that is lost in the kilns during the firing process, and transferring it to the dryers using thermal oil, avoiding additional energy usage during the drying process. With this process over 80% of the heat lost during the firing process is reused instead of wasted, without altering working conditions in the dryer.

ENDESA has already installed around 15 heat recovery systems in several Tile of Spain facilities. The ceramic companies expect to recover the investment and start to obtain profits from this new technology within two to three and a half years.
