Abstract
A novel batch-type kiln and a method of use thereof are provided. The kiln comprises a kiln body and a heating chamber disposed within the kiln body, which has a heater disposed therein. A table is disposed at the bottom of the heating chamber, the table having a peripheral portion and an upper surface for supporting an object to be treated. The peripheral portion of the table and a portion of the kiln body define a gap therebetween. This gap forms a gas-introducing path for introducing a gas into the heating chamber. The batch-type kiln is capable of preventing accumulation of a binder component in the gap between the table and the kiln wall.
