Specified Model of Vermiculite Heat Absorption While Burning in Electric Kilns with New Experimental Data
With the advent of a new electric kiln with movable hearth it is possible to determine experimentally the dependence of the density of expanded vermiculite on its temperature. Newexperimental data have shown that the previous model of heat absorption gave an overestimated result by value needed for full swelling of energy. The experimental results and calculationsare presented to demonstrate clearly the new specified and basic indices of model of vermiculite heat absorption. Experimental determination of the temperature of vermiculitefound that swelling it effectively requires up to twenty per cent less energy than previously thought according to the first model of heat absorption. And higher efficiency of structurizationprocess indicates several large energy efficiency electric ovens for roasting vermiculite.
