    Abstract: This invention relates to a system and a method of use for a gas recirculation heat exchanger to cast high purity silicon and/or grow crystals. The heat exchanger includes a hot surface for thermal contact with a crucible along with an inlet for flowing a gas to the heat exchanger and an outlet for flowing the gas from the heat exchanger. The exchanger also includes a baffle dividing the inlet from the outlet and for directing at least a portion of the gas over the hot surface, and a recirculation system adapted to cool the gas and return the gas to the heat exchanger. The heat exchanger can be easily tailored to local cooling needs.

    Abstract: A flue gas cooler 11 for cooling raw, hot flue gas from an electric arc furnace of an iron and steel production plant is provided. Each flue gas cooler 11 has a gas inlet chamber 14, a gas outlet chamber 16, and a matrix of gas cooling tubes 18 extending between and into the inlet chamber and the outlet chamber. Each gas cooling tube 18 has a bell-shaped inlet end 19 comprising an aerodynamically curved gas-accelerating profile effective to facilitate streamlined flow of flue gas into the gas cooling tube. The flue gas cooler makes it possible to receive flue gas directly from an electric arc furnace without getting clogged by dust and sublimates present in the flue gas.

    Abstract: An apparatus and method for unidirectionally solidifying high temperature materials comprising a graphite resistance furnace having a heat exchanger vertically positioned in the chamber thereof. The heat exchanger has inlet and exit means for the passage of an inert coolant gas therethrough. In operation, a crucible is loaded with a seed and the ceramic material to be melted and positioned in the interior of the chamber of the furnace in contact with the heat exchanger. The temperature of the melt is raised to about 50* C above its melting temperature. The melt temperature is slowly decreased with a correspondingly increase in the flow of the inert coolant gas through the heat exchanger thereby unidirectionally solidifying the material to produce a single crystal.
