Abstract
Working method in an elongated furnace to obtain the release at will of values of thermal energy in desired zones of the furnace, which comprises: the introduction of combustible gas heated at one end of the furnace; the transfer of the fuel gas to a front area or region of the furnace, area in which a given thermal condition is desired; the introduction into a point within said area of the quantity of oxygen gas required to react with the fuel gas so as to release the thermal energy values necessary to establish the desired thermal condition in said area; the progressive transfer of fuel gas to a more forward area or region and the repetition of the operation described for the desired release of thermal energy values in controlled quantity; and finally, in the vicinity of the forwardmost end of the furnace, the inflammation of the remaining fuel gas, in an essentially complete manner.
