Gas heating glass tempering furnace is a new type of tempering furnace that heats the glass sheets by burning CNG or LPG. LandGlass designed and developed high efficiency burners so that the gas can be combusted thoroughly and then, the heat is forced transferred to the glass surfaces and heating the glass. After heating, the hot glass sheets will be tempered and cooled. Gas heating glass tempering furnace includes loading table, gas heating convection furnace, quenching section, unloading table, electric control system, etc. Technical Features: 1) Heating the glass sheet by burning gas, which largely lower the installed capacity; 2) Combining the efficient combustion technology and jet heating convection technology; Self-produced burner ensures efficient combustion at high speed; Mature Jet Heating convection system ensures even and fast heating; 3) Clean heating environment inside furnace is assured by isolating combustion system; 4) Glass can be tempered includes: on-line and off-line Low-E (E=0.02) glass, screen printed glass, pattern glass, extra white glass, tinted glass, etc; 5) Interlock and ignition safety control system ensure safety use of gas.
