Calderys has launched CALDE® FD (Fast Dry), a refractory technology that can be used in many industrial applications, offering superior efficiency and reliability for all types of industrial furnaces.
In the field of cement bonded refractory castables, no matter the industrial process, furnace dry out is a critical challenge due to its duration; one that cannot be ignored. Following the completed installation of refractory lining, furnaces are unusable for up to several days to allow for dry out, which necessarily halts operations.
Calderys is targeting this directly by expanding its product offering in the CALDE® FD (Fast Dry) range. Crucially, the company says CALDE® FD products provide customers with enhanced reliability, less downtime, streamlined processes and improvements in CO2reductions. This expanded range was developed in alignment with Calderys’ ESG objectives to support customers in their energy transition needs.
Customers in boilers and incinerators operations are typically utility plants generating power or water supply for municipal grids, as well as waste management factories. Providing these essential services requires arranging alternatives during the non operational periods of their furnaces.
This will often involve buying back-up power from other suppliers or relying on generators that combust diesel or natural gas.
Understandably, such alternatives can be detrimental for customers, both economically and in terms of their carbon footprint. The new product mitigates this issue by providing the best technology available and reducing reliance on additional, external solutions. Cement bonded castables’ inherent sensitivity to rapid change will always require caution, but the robustness of the new product range cuts down time, allowing customers to quickly return to a fully operational state.
Longer dry out also means more energy needed. With this new technology and a lining thickness exceeding 100mm, CALDE® FD allows furnace operators to save up to 72 hours to reach a temperature of 1,200°C, helping them save energy during their operations.
