US Patent 10125041 Glass melting plant

A glass melting plant having a melting tank having end-fired heating, the melting tank having a feeding material inlet, an outlet for removing the molten glass, and a melt surface of at least 40 m2. At least one doghouse is laterally situated and is connected to the melting tank inlet for feeding material input. The doghouse has side walls that, together with the melting tank inlet, limit a feeding surface area, and has a feeding device. The doghouse has a roof with an end wall oriented toward the feeding device, which end wall encloses, with the roof, a gas compartment open toward the melting tank. To increase the specific melting performance with at least equal glass quality, the feeding surface of the doghouse is at least 8 m2 and, given a melt surface of at least 115 m2, is at least 7% of the melting tank melt surface.
