Abstract

See full text

The furnace of the facility includes partitions in which hot gases from the baking of carbonaceous blocks circulate, and heating ramps (21, 22, 23) revolving in relation to the furnace, equipped with burners or fuel injectors. Gas circulation lines (24) are defined along the partitions between an air blowing leg (20) and a corresponding gas suction leg (12). To detect even partial partition blocking of a partition, the process includes, on a continuous basis: a. for each gas circulation line, continuous recording of at least one of the following measured parameters: temperature, pressure, flow, oxygen concentration and carbon monoxide concentration; b. evaluation of at least one factor from the measured parameters; c. comparison of this factor with a corresponding reference value; d. emission of a malfunctioning signal when the comparison between the factor and the corresponding reference value does not meet with the predefined safety criteria.
