Improvement of Electric Furnace Energy Efficiency for Firing Vermiculite Due to “Zero Modules” Not Requiring Electrical Energy

HEAT ENGINEERING
  • 13 Downloads

Questions are considered for improving the energy efficiency of electric modular-pouring furnaces due to use of thermal exergy of expanding vermiculite grains. In order to create favorable conditions for transformation of accumulated heat into energy from final dehydration and structure formation a so-called “zero” module is introduced into the furnace construction, not requiring electrical energy. In contrast to other versions, this additional module is vibration-active and provides movement of expanded grains with single-layer continuous flow without breaks or gaps. This flow structure makes it possible to use heat accumulated by vermiculite and inert material most effectively.
