FURNACE FOR TRANSPORTING GLASS AND TRANSPORTATION OF GLASS IN SAID FURNACE

摘要

PURPOSE:To form Na2SO4 layer having necessary minimum thickness on the surface of glass, to protect glass and not to make contamination prominent by measuring concentration of sulfur oxide (SOx) in a gas in a furnace for transporting glass and controlling concentration of SOx. CONSTITUTION:A feed pipe 11 to supply SOx and a suction pipe 12 to suck the gas in the furnace are set in the furnace 1 for transporting glass G. SOx concentration in the gas in the furnace sucked by the pipe 12 is measured by a concentration meter 14 and compared with a set value. Then divergence of a valve 16 is regulated depending upon the measured result. SOx concentration in the furnace is controlled in 2-3.3ppm.
