The Gill furnace (named after its inventor, engineer Roberto Gill, native of Marsala) is a sulfur separation system from the crude ore to the fusion furnace of the most advanced conception of the calcarone of which it is the finishing ; is made up of a series of units, almost identical, placed in battery.
The Gill furnace system, so called by the name of its creator, was introduced since 1880 in Sicily in the Gibellini and Racalmuto mines, Cabernardi, in the Province of Ancona, in Trabia, Caltanissetta. This system starts from the principle of the reuse of heat produced by the first conveyor caliper and used to merge the further quantity. Essentially it consists of two or more adjacent cells placed in communication through a horizontal duct placed high and locked by a cell-cell gateway. the end of this is a chimney.
Mineral charge comes from the top of the cap cover. The sloping floor of the rooms is similar to the calcareous floor and ends at the bottom with the openings of the melting material. Once the first cell (driving cell) is switched on, the heat of this, which reaches more than 200 degrees, conveyed in the second is sufficient to cause the fusion of this load, and so on for the various battery units.
The rediscovered, called improved sulfur fusion method to extract it from its minerals, had been patented by its inventor who had obtained it with a certificate no. 874 of October 22, 1872. On 13 November 1876, along with its rights of use, the English sulfur fusion company limited in London was ceded by a public deed issued by London notary William Grain, registered in Turin on 28 November with the n. 17571 and published in the Official Journal of the Kingdom of Italy, n. 124, May 28, 1877, p. 2117.
Despite the best performance, the Gill furnace diffusion was lower than that of previous systems. Notemodify wikitesto Voices correlateemodify wikitesto
