Mixed hot air heating device of TFT -LCD glass kiln heating -up furnace

The utility model discloses a TFT the mixed hot air heating device of LCD glass kiln heating -up furnace, including the burning mixing chamber, burning mixing chamber one end is equipped with naturalgas import, the other end is equipped with burning hot air exitus, burning mixing chamber lateral wall is equipped with the oxygen inlet in the intercommunication burning mixing chamber, air inlet andhot -blast air -out muzzle, during the heating -up furnace, insert oxygen pipeline, through solenoid valve control oxygen, the input of the natural gas and air, thereby make combustion gas reach optimum ratio, the assurance gas is fully burnt, eliminate not fully burning formation carbon dust pollution of gas in the hot air heating device combustion chamber, smoke exhaust fan bears too bigly because the air input is too big to solve the heating -up furnace later stage, the difficult problem of furnace pressure control, it produces not have long -pending charcoal, hot -blast rate of ventilation and furnace pressure red
