  • Static furnace for the thermal decomposition of solids at high temperatures by thermal radiation
    Patent number: 6149425
    Abstract: A furnace for the thermal decomposition of solids by thermal radiation having an inlet for admitting the solids at an upper part with the solids dropping by gravity in the furnace. There is at least one heated radiator body within the furnace below the inlet to produce radiant heat energy to decompose the solids dropping in the furnace and the gases produced by the decomposition rise in the furnace to preheat the solids admitted at the inlet. The furnace also includes a heat exchanger whose liquid is heated by the decomposed solids, and there are a plurality of radiator bodies each in the form of a closed chamber with a burner to heat a plate which radiates the heat.
