The utility model discloses a three-passage regenerative chamber of a glass furnace, which comprises a regenerative chamber body. The three-passage regenerative chamber is characterized in that an air inlet is formed on one side of the chamber body, and an air outlet is formed on the other side of the chamber body; and two furnace walls are arranged inside the chamber body to partition the regenerative chamber into three parts, wherein air passages are respectively reserved between the upper end of the first furnace wall and the chamber body as well as between the lower end of the second furnace wall and the chamber body. The partition plate inside the regenerative chamber to partition the regenerative chamber into three parts is additionally arranged, so as to increase the area of the regenerative chamber, increase the preheating temperature of air, increase the volume of checker work and improve the regenerative capacity.
