Standard text books learn that radiation is the main heat transport system at higher temperatures. For that reason, most people don’t realize that radiation can be important at lower temperatures. The most popular example at room temperature is the low-E double glazing. Indeed, installing a low-E coating on the warm pane of the double glazing halves the thermal conductivity of

Energy consumption of a float glass lehr

In case of production lines of 250 TPD and more, heating is not needed for standard thicknesses. From the dross box until 450°C, we have to work with controlled cooling without forced convection in order to achieve the requested residual stress for a proper glass cutting and processing afterwards.  The glass is able to radiate to heat exchangers under and

The famous history of the CNUD flat/float glass lehr

The CNUD flat / float glass lehr has a long history which is absolutely worth to be studied because it explains at the same time the current lay out of a lehr. In the past, it was general practice for flat (rolled) glass to work with a ceramic tunnel (and radiation cooling) down to 300°C. Below 300°C, forced convection (F-zone) was
