Abstract:
1. A method for manufacturing lime for limestone, the method comprising: a) providing a regenerating oven for manufacturing lime from limestone, the oven comprising at least one vat, where the vat comprises a top, a bottom, an external wall connecting the top and the bottom and an internal wall connecting the top and the bottom, where the external wall is longer than the internal wall, and where the vat further comprises a device for selectively dispensing limestone granules either toward the external wall of the vat or toward the internal wall of the vat, the device comprising: b) dividing a load of limestone granules into a first batch of limestone granules and a second batch of limestone granules, where the first batch of limestone granules has a greater size than the second batch of limestone granules; c) actuating the actuator to incline the mobile bulkhead by the first angle; d) loading either the first batch of limestone granules into the vat or the second batch of limestone granules into the vat; e) actuating the actuator to incline the mobile bulkhead by the second angle; f) loading a remaining batch of limestone granules into the vat; and g) heating the limestone generating combustion fumes, and allowing the combustion fumes to preferentially travel along the external wall of the vat; where steps c) through f) arrange more of the first batch of limestone granules against the external wall of the vat than against the internal wall, and arrange more of the second batch of limestone granules against the internal wall of the vat than against the external wall which creates a lower-resistance path to a flow of the combustion fumes towards the top of the vat along the external wall of the vat as compared to along the internal wall of the vat; and where allowing the combustion fumes to preferentially travel along the external wall of the vat releases a greater amount of heat in a more homogeneous way through the limestone granules than would be released if the limestone granules were not arranged before heating according to steps c) through f).
