Abstract
The invention relates to method and apparatus for cooling a furnace configured for processing refractory composites. More specifically, the invention is directed to method and apparatus for cooling a furnace more rapidly than prior art methods. According to the invention, a cooling gas is flowed in a closed circuit through the furnace, over the refractory composites disposed within the furnace, and over a cooling element disposed within the furnace. The cooling gas may be flowed by natural convection or by force.
Claims11
A method for cooling a furnace configured to process refractory composites, comprising the steps of:
- flowing a cooling gas in a closed circuit through said furnace, over said refractory composites disposed within said furnace, and over a cooling element disposed within said furnace.
A method for cooling a furnace configured to process refractory composites, comprising the steps of:
- flowing a cooling gas comprising a predetermined ratio of gasses in a closed circuit through said furnace, over refractory composites disposed within said furnace, and over a cooling element disposed within said furnace.
A method for cooling a furnace configured to process refractory composites, comprising the steps of:
- flowing a cooling gas through a closed circuit, over said refractory composites disposed within said furnace, and over a cooling element disposed within said furnace, said closed circuit including said furnace and a blower disposed outside said furnace.
A method of cooling a furnace configured to process refractory composites, comprising the steps of:
- circulating a cooling gas through said furnace;
- and,
- changing the composition of said cooling gas to effect the rate at which said furnace is cooled.
