PCT No. PCT/BR95/00033 Sec. 371 Date Feb. 27, 1997 Sec. 102(e) Date Feb. 27, 1997 PCT Filed Jun. 28, 1995 PCT Pub. No. WO97/01615 PCT Pub. Date Jan. 16, 1997A 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.
