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.
Claims12
A furnace for the thermal decomposition of solids by thermal radiation comprising:
- an inlet for admitting the solids at an upper part of said furnace, the solids dropping by gravity into a reaction zone in the furnace;
- at least one heated radiator body within said furnace below said inlet to produce radiant heat energy radiated to said reaction zone to decompose the solids dropping in the furnace, the gases produced by the decomposition rising in said furnace to preheat the solids admitted at said inlet;
- and
- a heat source external of said furnace reaction zone producing the heat to heat said radiator body to produce radiant heat energy.
A furnace for the thermal decomposition of solids by thermal radiation comprising:
- an inlet for admitting the solids at an upper part of said furnace, the solids dropping by gravity in the furnace;
- at least one heated radiator body within said furnace below said inlet to produce radiant heat energy to decompose the solids dropping in the furnace, the gases produced by the decomposition rising in said furnace to preheat the solids admitted at said inlet;
- and
- a cooling unit below said at least one radiator body which comprises a heat exchanger to collect the heat of the solids decomposed by the thermal radiation.
A furnace for the thermal decomposition of solids by thermal radiation comprising:
- an inlet for admitting the solids at an upper part of said furnace, the solids dropping by gravity in the furnace;
- at least one heated radiator body within said furnace below said inlet to produce radiant heat energy to decompose the solids dropping in the furnace, the gases produced by the decomposition rising in said furnace to preheat the solids admitted at said inlet wherein said at least one radiator body comprises a closed chamber including a burner and a ceramic plate heated by said burner serving as said heat radiator body.
A furnace for the thermal decomposition of solids by thermal radiation comprising:
- an inlet for admitting the solids at an upper part of said furnace, the solids dropping by gravity in the furnace;
- at least one heated radiator body within said furnace below said inlet to produce radiant heat energy to decompose the solids dropping in the furnace, the gases produced by the decomposition rising in said furnace to preheat the solids admitted at said inlet, wherein said at least one radiator body includes a plate extending substantially vertically in said furnace for radiating heat, the solids dropping in said furnace passing by said plate being heated by thermal radiation.
