Abstract
A process for regulating a furnace which includes a sequence of sections, cooling sections, baking sections, and preheating sections, in which the preheating sections at the tail are fitted with exhaust pipes for combustion gases, and in the transverse direction with a series of flue walls and pits in which blocks containing carbon to be baked are stacked, in which gas streams circulate through the flue walls. The mass flow in each of the streams of combustion exhaust gases is regulated by measuring this flow and the temperature in order to obtain a predetermined set value of energy flux.
