ABSTRACT:
A glass delivery system is disclosed having a glass conducting pipe enclosed within a refractory structure. The refractory structure is spaced about the pipe and defines a closed space for receiving therein a quantity of the glass. Flow control means is provided for regulating flow through the pipe. Means is further provided for isolating the flow control device from glass in the closed space to thereby avoid a bypass of said flow control device. A method for operating a glass delivery system is also disclosed.
