Improvements to the method and to the device for optimising combustion in batch furnaces for baking carbon blocks

摘要

The invention relates to a method for optimising combustion in a batch furnace for baking carbon-containing blocks, according to claim 1 of the main patent, in which method the delivery rate of the fan 1 is adjusted so as continuously to inject the quantity of air which is necessary and sufficient to obtain complete combustion both of the volatile materials released during the baking of the carbon-containing blocks, and of the fuel injected into the burners 5. The overpressure in the walls of the chambers 3 situated behind the full-burning zone is adjusted to a value lying between 0.5 and 5 mm water column (i.e. approximately 5 to 50 Pa) and preferably between 1 and 2 mm water column (i.e. approximately 10 to 20 Pa). <IMAGE>
