Abstract
A furnace particularly for heat treatments of glass sheets (12), comprising a longitudinally-elongated chamber which contains roller conveyor elements (11) for the glass sheets (12). The furnace comprises irradiation-heating elements (13, 14) combined with first (18) and second (24) elements for heating by forced air convection in which the air temperature is controlled by adjusting its circulation rate, the elements being located respectively above and below the conveyor elements (11) and therefore above and below the sheets (12) being treated.
