Webeasily leads to problems with the refractory material and can cause refractory bricks to fall off. As the protecting layer is then damaged and its thickness reduced, hot spots are formed inside the shell, which results in loss of energy and disturbed kiln operation. To protect the steel shell from damage, its temperature should remain below 350°C. WebIn fact, producing just one tonne of ceramic tiles requires 1.67 MWh of energy. Most of this energy (55%) is used during the firing process, where clay and glazes are brought to a very high temperature. This heating is typically done with natural gas which, as a fossil fuel, means the process produces a substantial amount of greenhouse gases.
