Abstract
PROCEDURE FOR THE EXECUTION OF DISCRETIONAL ENDOTHERMAL PROCESSES IN THE CUBA FURNACES, FOR EXAMPLE FOR THE COMBUSTION OF LIME, in which the combustion material is heated in a first zone, subjecting itself immediately to the action of a fuel and in the next one to a refrigeration, the preheating zone being crossed by at least a part of the thermal carrier necessary for the combustion process, alternatively in a uniform and countercurrent flow, so that the resulting thermal surplus in the conventional furnaces of Cuba can be made once again usable in the preheating zone for the combustion process, in which, in addition, it operates with two tub furnaces, linked together by the lower part of the heating zone, in such a way that in the first thermal period Fresh combustion air (primary air) is introduced into one of the wells, above the continuous preheating zone tion in a uniform current through the combustion zone, and, finally, through a well or channel communication, in the second of the wells, going upstream and countercurrent to go outside together with the resulting exhaust gas, introducing air Secondary in one or both wells, in countercurrent and at the bottom of the cooling zone, joining with the primary air, and repeating after which, alternatively, this process in a second combustion period, by inversion, characterized because the fuel is added to the combustion material at more than one point and in different quantities, so that part of the fuel is initially burned with the cooling air introduced into the well from the bottom.
