ABSTRACT:
Apparatus for pyrolytically forming an oxide coating on an upper face of a moving, hot glass substrate, including a substrate path and a downwardly opening hood positioned along the substrate path and defining together with the substrate path a coating chamber; support device for conveying a hot glass substrate along the substrate path past the coating chamber; a device for introducing coating precursor material in the vapor phase into a carrier gas stream comprised of a carrier gas including a device for inducing turbulence in the carrier gas stream to ensure intimate mixing of the carrier gas and the coating precursor material; a device including at least one venturi for introducing oxygen into the precursor-containing carrier gas stream before it enters the coating chamber and provide a gas mixture stream; a device for supplying to the coating chamber the gas mixture stream; and a device for aspirating atmosphere including coating reaction products and unused coating precursor material from the coating chamber.
