Cement Ozarów Reduces CO2 Emissions with Qlar’s Schenck Process Technology Upgrade
Cement Ozarów, part of the CRH Group, is leading the way in reducing CO2 emissions in the cement production process by adopting Qlar’s innovative MULTICELL MIN XR technology. This upgrade to their existing plant is helping the Polish cement producer enhance the use of alternative fuels (AFs), reduce reliance on coal, and improve the precision of coal dosing—all while contributing significantly to environmental sustainability.
Historically, the plant used fossil fuels, including coal, to fire its kilns. However, over the last two decades, Cement Ozarów has gradually shifted to using more alternative fuels, such as hard-to-recycle household waste, as a primary energy source. This change has notably decreased their coal consumption, and the implementation of Qlar’s system takes the process further by enabling more accurate and smaller-scale coal dosing. Qlar’s MULTICELL MIN XR technology is ideal for retrofitting existing infrastructure, allowing the plant to modernize its coal feeding system without requiring a complete overhaul. The new system supports precise coal dosing at low feed rates while ensuring high throughput during start-up processes. This helps maintain stability in the kiln even when the quality of alternative fuels fluctuates.
The system’s design also reduces coal usage, enabling significant fuel cost savings—up to €900,000 annually. The upgraded technology is seamlessly integrated with the existing equipment and has already shown results that exceed expectations. Cement Ozarów has reduced coal feed rates to as low as 0.3 t/h, surpassing the original specifications, which enhances sustainability and operational efficiency. The upgrade not only supports the plant’s efforts to meet emission targets but also delivers a quick return on investment due to the substantial savings on fuel costs. As of November 2023, the new system has been in full operation, marking a significant milestone in Cement Ozarów’s environmental strategy. This successful implementation demonstrates how incremental technological upgrades can provide both operational and environmental benefits, reducing CO2 emissions while optimizing production processes.
