Method for the cooling and heat recovery from materials at very high temperature

A method for the controlled cooling of and heat recovery from materials at a high temperature, comprising of:

• a)—conveying high-temperature material at the high temperature into a mixing system, wherein the high temperature is between 1,300° C. and 1,600° C.;
• b)—transporting mixed material exiting the mixing system inside a continuous flow channel;
• c)—carrying out a step of heat recovery from the transported mixed material;
• d)—feeding a flow of the mixed material exiting at a low temperature from the continuous flow channel to a flow dividing system configured to divide the mixed material exiting at the low temperature into at least a recovered portion of the mixed material and a discard portion of the mixed material;
• e)—recovering the recovered portion of the mixed material exiting the flow dividing system;
• f)—moving the recovered portion of the mixed material at the low temperature by means of a moving and recirculating system adapted to re-introduce exclusively the recovered portion of the mixed material for direct mixing with the high-temperature material;
• and
• g)—conveying the recovered portion of the mixed material at low temperature and mixing the recovered portion of the mixed material at a temperature between 50° C. and 400° C. with the high-temperature material at the high temperature in the mixing system, thereby reducing the temperature of the high-temperature material.
