Evaluation de l’inertie thermique du four a combustible petrole lampant atomise a la vapeur d’eau

Abstract

To appreciate time that it is necessary to start and that necessary to cool the kiln with fuel paraffin oil atomised with the water vapour we carried out tests allowing to evaluate its thermal inertia. Thus, the variation of the temperatures according to time was examined during the rise in  emperature and the cooling of the kiln. A time-constant of 3h 05mn 12s is observed during the firing operation of the empty kiln and 5h 33mn
20s during firing operation of the charged chrged. In the same way a time-constant of 4h 36mn 06s is observed during the cooling of the empty kiln and 5h 33mn 17s during cooling of the charged kiln. That should help a better quality control of firing the ceramic products and allow other possible uses of the kiln.
