THE INVESTIGATION OF THE PHYSICAL ANALOGUE FOR THE VERMICULITE BURNING ELECTRIC KILN WITH «ZERO» MODULE

Abstract

The experimental investigating results are regarded in the article for the pilot plant kiln which was used to proof the vermiculite grains capability to complete both the thermal absorption and structure formation at the expense of the vermiculite's exergia transformation into the mechanical energy taking place in so called «zero» module when the energy consumption is reduced. The dependencies were deduced from the experiments  of the bloated product's density both at the entrance into the «zero» module and at its exit on the heater's surfaces temperature at the electric modules of the kiln. The time was defined the vermiculite grains took to move through the «zero» module, and the heat absorption completeness coefficient was determined which corrects the analytical model of the process. The analytical expression was given for the vermiculite heat absorption description in case of unfinished heat absorbing inside the electric modules given the correcting heat absorption completeness  coefficient. It was shown that the «zero» module application can reduce by 10‒20 % the energy consumption and the burning power capacity depending on the «zero» module mounting location.
