Abstract:
1. A glass-melting furnace for changing glass raw material particles into liquid glass particles in a gas phase atmosphere in the glass-melting furnace, accumulating the liquid glass particles in a bottom portion of the glass-melting furnace to obtain a molten glass liquid and discharging the molten glass liquid, the glass-melting furnace comprising: a glass raw material particle feed portion disposed downwardly at a furnace wall portion in an upper portion of the glass-melting furnace; a heating device provided under the glass-raw material feed portion in the glass-melting furnace for forming a gas phase portion for changing glass raw material particles into liquid glass particles; an inlet of a flue disposed on an upstream side of the gas phase portion, relative to a flow direction of the molten glass liquid, wherein the inlet of the flue is disposed such that an upper edge portion of the inlet is located at a position below a half of the distance between the molten glass liquid surface and a ceiling inner wall surface of the glass-melting furnace; a furnace-bottom portion for accumulating the liquid glass particles to produce an accumulated molten glass liquid; a discharge portion for discharging the accumulated molten glass liquid; and a drain-out portion formed under the flue, said drain-out portion comprising a drain-out bottom, a drain-out discharge, and a dam for separating a drain-out molten glass liquid in the drain-out bottom from the accumulated molten glass liquid in the furnace-bottom portion, wherein the drain-out bottom and the flue are situated such that a reacted product that falls from the flue is captured in the drain-out bottom and thereby separated from the accumulated molten glass liquid in the furnace-bottom portion.
