Finally, the electromagnetic relay 53 controls the opening and closing of the flow control valve 61 to control the gas input into the furnace body 2, so that the amount of gas input can be automatically controlled by the remote end, thereby controlling the temperature in the furnace body 2 and reducing the atmosphere for firing by controlling the ratio of oxygen and liquefied gas. The electromagnetic relay 53 can be connected to the igniter 72 through a wire, so that the kiln can be remotely ignited by the control of the controller 69, which is more convenient for the use of the kiln and better protects the life safety of the kiln workers.

[0039] When the present invention is in use, it is only necessary to manually push the kiln car 15 into the furnace body and then close the sealing door 19. The electromagnetic relay 53 controls the opening and closing of the flow control valve 61, so that the air and gas enter the combustion tube 12 through the mixing tube 10 and the ventilation tube 9. Then, the igniter 72 controls the ignition rod 8 to ignite the mixed fuel in the combustion tube 7 to start the firing of celadon. During the process, the opening size of the flow control valve 61 can be controlled by controlling the electromagnetic relay 53, so as to control the proportion of the gas input into the furnace body 2 to meet different firing requirements. The hot air generated during the firing process enters the exhaust pipe 37 on the inner side of the left and right walls of the furnace body 2 from the furnace body 2 through the ventilation hole 34, the first ventilation channel 35 and the second ventilation channel 36, so that the hot air in the furnace body 2 will not be quickly discharged from the furnace body 2, so that the temperature in the furnace body 2 remains stable, the consistency of the product is good, and more gas is saved.

[0040] Although the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
