Variable length furnace for firing ceramics - in a single layer having removable segments of preheating and cooling regions

摘要

Tunnel kiln for firing ceramic products in a single layer, the height of which does not exceed 10-15 cm, includes appts. for bringing about a lengthening or shortening of the preheating and cooling zones, as a function of the prods. to be fired. The appts. consists of removable sections held in waiting away from the kiln, which can be included in its length. The furnace can be rapidly modified for a change of product to be fired. The amt. of heat consumed during firing can be minimised. The heating and cooling zones can be lengthened or shortened independently. Loading materials are avoided completely.
