When the firing device is in operation, the heat generated by the glass in the firing tube and the impurities are attracted by the first turbine fan, filtered, and then enter the heat storage chamber through the connecting pipe and the first heat pipe for storage, absorbing the waste gas and heat generated during the glass production process, reducing the contact between the waste gas and the molten glass, avoiding the generation of bubbles in the glass liquid, and increasing the strength of the produced glassware. At the same time, after absorbing the heat generated by combustion, the heat is reused, which is green and environmentally friendly. The temperature of the glassware is obtained by a temperature sensor, and the temperature is controlled to decrease reasonably. When the temperature is too low, the second electromagnetic valve and the fourth electromagnetic valve are opened, and the second turbine fan blade is opened. The heat is released from the heat storage chamber and leaves the heat collecting and releasing device through the release port, which increases the temperature around the glassware, so that the decreased temperature meets the required temperature for glass annealing, and the thermal stress generated in the glass belt is not fully eliminated, which may cause explosion. When the heat enters and exits the heat collecting and releasing device, it passes through the filter layer twice for filtration, so that the harmful substances in the waste gas and heat are filtered and adsorbed, avoiding the attachment of harmful substances in the device, and prolonging the service life of the device.
