Steklarna Hrastnik is the winner of energy efficiency wise practice

The companies Tiko Pro and Mediade performed a contest in best practices of energy efficiency for the first time this year. Steklarna Hrastnik received the award for best and wisest practice in competition with 19 Slovenian companies and organizations, and 22 wise practices that were registered. They received the award for the project of exploitation of waste thermal flue gas for water heating. Steklarna Hrastnik saves 130,000 Sm3 of natural gas per year with this project which amounts to € 50,000 and reduces CO ₂ emissions by over 250 tonnes.

All the entries were reviewed by an expert committee, which consisted of Kristina Kočet, Tiko Pro, Milan Ziherl, Eco Fund, Igor Podbelšek, Electro Energy, Dr. Ignacijo Biluš, Faculty of Engineering, University of Maribor, Aleksandra Brank, Bisnode, Mateja Kegel, and Edita Krajnović, Mediade. The committee selected a winner of Wise Practices 2013 among three finalists. In assessing these wise practices, the committee took into account the following criteria: environmental (energy) efficiency, transferability of practice, practice innovation, economic impact and wider social significance and range of good practice.

"I am pleased that the committee chose our project as the wisest best practice of this year. Concern for the environment is of strategic importance for Steklarna Hrastnik, so all of our technology updates are made on the basis of the strictest standards and regulations," said Andrej Božič, General Manager of Steklarna Hrastnik and added: "We also carry out targeted actions based on monitoring of environmental indicators and energy audits, which are performed during chosen periods."

One of the energy audits in Steklarna Hrastnik showed that there is potential for exploiting waste flue gas from the G furnace, the temperature of which is 1300 ° C. All waste flue gas can pass through the filter only at a temperature below 180 ° C. Cooling of it means energy consumption and possible resulting in environmental burden. Therefore, Steklarna Hrastnik was looking for the possibility of cooling the waste flue gas with lower energy consumption. This resulted in the award-winning project. The whole process starts with adding fresh air to waste flue gas. With this, the temperature is reduced to 450 ° C. Water is heated with this mixture in two heat exchangers and cools the mixture even further for additional 100 ° C. Then the heated water is used for the gasification of oxygen and in the end, the cooled flue gas goes through a clearing filter. The project will repay itself to Steklarna Hrastnik in less than two years.
