The side refractory stone is a heat-resistant component used to line the combustion chamber of boilers and burners. It protects the outer structure from extreme temperatures and helps reflect heat back into the fire, improving efficiency. This stone is designed to fit specific models and provides reliable insulation. Replacing worn refractory stones is an important part of boiler maintenance and repair, ensuring safe and efficient operation.
