Portugal: Cimpor has reported the successful installation of a new KHD Pyrorotor combustion chamber at its Alhandra plant. It described the upgrade as a key milestone in the modernisation of Kiln 7 and in the company’s energy transition process.
The combustion chamber measures 3.4m in diameter and 10m in length, and weighs 146t. It will allow the replacement of fossil fuels with alternative fuels, enabling a thermal substitution rate of up to 80%. Its installation required a technically demanding operation, carried out using a 400t crawler crane. The work is part of a wider structural upgrade of Kiln 7, which also includes the modernisation of the existing kiln to a production capacity of 3600t/day, a new preheater tower with a five-stage cyclone, the installation of a Pyroclon calciner, a new clinker cooler and a new vertical raw mill.
Cimpor says that the investment will contribute directly to the reduction of the plant’s CO₂ emissions, fully aligned with the company’s decarbonisation goals and reinforcing the company’s commitment to the targets set out in its Recovery and Resilience Plan.
