自動的にプッンユされる。The continuous firing furnace 1 has a tunnel-shaped furnace body 3 placed horizontally on a base 2. The boxes 5, which contain objects to be fired (not shown) and are stacked in multiple stages on the base plate 4, pass through the inside of the furnace body 3 from the entrance 6 of the furnace body 3, and pass through the inside of the furnace body 3.
As shown by the arrow A1, it is first automatically pushed into the preheating zone following the inlet 6 of the furnace body 3 by the pusher 8 toward the exit lower part of the furnace body 3.

えたことを特徴としている。However, in this case, the air sent into the furnace body 3 causes a drift within the furnace body 3, making it impossible to uniformly heat the object to be fired, and the ceramic combustion gas is injected into the combustion scum. A gas burner ejects into the furnace body from the outlet, an electric heater placed under the ceiling of the furnace body at a distance between the inlet and the outlet, and a gas burner that is generated inside the furnace body when firing the object to be fired. It is characterized by being equipped with a flue for discharging materials out of the furnace body.
