Electric Modular-Trigger Kiln with an Energy Recuperation System for Firing Vermiculte Concentrates

Abstract

Possibilities are considered for improving the energy efficiency of electric modular-trigger kilns for firing vermiculite concentrates. Rationale is given for introduction into the kiln construction of an additional “zero” module using secondary energy resources. A model of vermiculate thermal assimilation is provided, which takes account of thermal exergy accumulated within it, absorbed on heating, and transferred in a “zero” module into energy of grain mechanical transformation. In order to reduce loss of this exergy by vermiculite an original construction is proposed for a “zero” module, and prediction of the energy efficiency these kilns is provided.
