We have used ceramic materials that made their technological debut in high-power burners, where they operated under constant and high thermal load. We have taken an uncompromising approach to quality control, manufacturing technology and the materials used, applying heat-resistant concrete reinforced with polypropylene fibres and dispersed reinforcement made of heat-resistant wire. The modular ceramic design ensures easy replacement and, once removed, provides full access to the entire combustion chamber, making service work easier.
