Abstract: The present invention provides a stain-resistant glass and a method of making such a glass. In accordance with the method of the invention, SO3 is applied to the upper surface of a sheet of float glass in an amount sufficient to reduce staining of the glass. In a preferred embodiment, the oxygen-containing gas and SO2 gas are supplied in a lehr adjacent the float bath at a temperature of at least about 800 DEG F (about 425 DEG C). In one aspect of the invention, a hood (30) having a gas delivery system (40) is provided, with the hood defining a downwardly open enclosure and enclosing a portion of the delivery system. The hood is optimally disposed above a ribbon of float glass (25) in an annealing lehr (20) and the delivery system may include a sparge pipe for delivering either SO2 or SO3 gas to the hood.

Abstract translation: 本发明提供一种防污玻璃及其制造方法。 根据本发明的方法，将SO 3以足以减少玻璃污染的量施加到浮法玻璃片的上表面。 在一个优选的实施方案中，含氧气体和SO 2气体在至少约800°F（约425℃）的温度下在与浮液浴相邻的退火炉中供应。 在本发明的一个方面，提供了一种具有气体输送系统（40）的罩（30），其中罩罩限定向下开口的外壳并且包围输送系统的一部分。 发动机罩优选地设置在退火炉（20）中的浮法玻璃带（25）之上，并且输送系统可以包括用于将SO 2或SO 3气体输送到发动机罩的喷射管。
