摘要

Improvements in the object of the main patent no. 232529 for improvements in gypsum kilns and similar building materials, which affect the economic factors of the chain structure of these kilns, also facilitating their more perfect adaptation to the orography of the mineral deposits that are intended to benefit, collect together and in combination the following essential conditions: A) a simplification in the lower combustión tunnel based on forming it with two vertical and parallel parameters that in their superior prolongation will form the chain of cooking ovens; filling the intermediate space, in its lower part, with casting slag tuffs, involving simple refractory and perforated tubes arranged parallel to the chain axis, forming with these same tobas the sole plate, or the solera of the upper cooking chain, and covering this channel with removable plates; B) give an orientation of the chain according to the line of maximum slope, when the orographic conditions allow it to suppress the chimney and reduce the forced draft; C) mainly in condition (b) the suppression of the transverse walls of the cooking chambers, reducing to a simple channel covered with the upper plates; D) facilitate the cooking process with transversal tubes cross-linked with the longitudinal ones to which lighters are applied in their lateral mouths; D) facilitate the cooking process with transversal tubes cross-linked in the longitudinal ones to which lighters are applied in their lateral mouths.
