Grenzebach › Industries › Glass › Float Glass › Waste Heat Recovery Waste heat recovery - a green approach FLOAT GLASS PRODUCTION Two of the glass industry’s key challenges include cutting energy consumption during consumption and minimizing the level of CO2 emissions. We offer a cutting-edge, waste heat recovery system for glass plants so that you can achieve climate targets and ensure you receive your operating licenses in the future. And the combined forces of the Grenzebach and CNUD EFCO GFT teams are working on further improvements. Heat is an asset. You should make it earn interest. The problem: during the glass melting process, much of the energy in the exhaust gas from the glass melting tanks is lost. WHR systems use this waste heat to generate electrical power, as well as heat and cooling energy for process and air-conditioning purposes. This leads to a significant increase in energy efficiency, an improvement in the climate protection balance due to avoided C02 emissions, and considerable cost savings by reducing the amount of electricity and fossil fuel that has to be purchased. Overview of benefits Achievement of climate goals The European glass industry has committed itself to reducing CO2 emissions by over 20% by 2030, and the political pressure to achieve this goal will be even stronger in the future. WHR plants from Grenzebach and CNUD EFCO GFT can make a real contribution here on the basis of a proven, controlled technology. They offer the highest efficiency, the highest electrical power generation rates and outstanding availability under almost all operating conditions. Cost savings WHR plants generate electricity and, if required, heat and cooling energy. The consequent reduced need to buy energy leads to significant cost savings. Incredible but true: the use of our WHR systems on standard glass melting tanks enables the generation of all the electrical energy required to operate the flat glass production line! System integration and facility performance Our WHR systems are exclusively equipped with proven technology derived from power plant construction. Their smart integration into the production process means that the glass manufacturing process remains almost unaffected. Furthermore, there is a chance to achieve additional benefits by reducing operating or investment costs for peripheral equipment. A YouTube video starts when you click the play button.

Video: Waste heat recovery system for glass industry “Climate protection and energy efficiency are huge issues for the glass industry and gaining momentum due to legislation and companies’ own targets. Waste heat recovery can be implemented today, even if the whole plant may be operated with hydrogen in the future. We’re developing agile solutions for the real world each and every day.” DENNIS SCHATTAUER Managing Director at German Floatglass Technology GmbH The process WASTE HEAT RECOVERY (WHR) Based on controlled and proven technology, waste heat recovery plants enable improvements in energy efficiency and the reduction of resource consumption. The solution from Grenzebach and CNUD EFCO GFT stands out from other systems on the market due to its particularly high efficiency for power generation, which can be 35 percent or more. The WHR system uses the available thermal energy in the melting tank exhaust gas to produce steam at pressures up to 90 bar by integrating heat exchanger boiler systems into the exhaust gas flow. The steam is fed to the highly efficient turbine/generator unit to generate electrical energy. Partnership and service that go the extra mile. OUR SERVICE FOR THE GLASS INDUSTRY Construction and commissioning of a new glass production line is only the first stage in a good customer relationship. Professional service in daily operation is just as important: We want your investment to be profitable without any interruption – that’s why our engineers are there for you with guidance and support over the entire life cycle of the plant.
