A novel technique for characterizing the performance of a forehearth is presented. It is based on performing an energy balance on the forehearth. There are four basic energy terms which enter the analysis: sensible heat of the glass, gas and electric energy input, flue and structural losses, and top and bottom cooling air requirements. The necessary data to estimate these energy terms was obtained from afield installation over a period of several months. The energy input us losses us gloss load results were plotted in three dimensional space. A best fit line through the data was then obtained. This line is the characteristic operating line for this particular forehearth. With this methodology the operating performance for any forehearth can be ascertained. The results will enable one to predict the energy consumption, forehearth and flue loss estimates, and cooling air requirements for a given tonnage pull and temperature drop requested by the forehearth operator.
