en.Wedoany.com Reported - Mannok's cement plant in Ballyconnell, Ireland, underwent a planned kiln shutdown in early 2026, during which a new kiln hood was installed and key upgrades were made to the cooling system. The original kiln cooler fixed inlet grate, installed in 2000, had deformed due to prolonged operation, leading to significant false air infiltration. This maintenance replaced the component with an ABC cooler inlet and outlet sealing system. Mannok reported measurable gains in energy efficiency following the upgrade, along with enhanced fuel switching capability. The company appointed Fuller as the engineering, procurement, and construction contractor, supplying the kiln hood, cooler inlet, and outlet sealing components, while G Leonard handled the refractory engineering. According to the company, the thermal substitution rate has significantly improved, and the cooler inlet no longer forms "snowmen" (i.e., molten clinker solidifying and accumulating on the grate), thereby reducing downtime and improving production reliability.

Paul Carron, Mannok's Decarbonization Engineering Manager, stated that such projects are central to the decarbonization strategy of Mannok's cement business, and the successful installation of the new kiln hood and ABC cooler components has already delivered tangible efficiency improvements and promoted greater use of alternative fuels. From initial planning to execution, the project ran very smoothly, reflecting strong collaboration between the internal team and partners. This marks a significant step forward in Mannok's decarbonization goals under its Vision 2030.
