Abstract
The presented study provides useful information about the tendencies for optimization of the heat generation in the working area of the fire refining furnace of blister copper. A theoretical analysis of the possibility for replacing of the used fuel oil with natural gas is made. For the porpuses of the present study in house software product ``GOR`` of the Department of Physical Metallurgy and Heat Aggregates at the University of Chemical Technology and Metallurgy, Sofia, is used. The change of the theoretical combustion temperature of both fuels under different process conditions is studied. It is found that at combustion of natural gas with 2 % oxygen enrichment of the oxidation stream, values comparable to the theoretical combustion temperature of the fuel oil are achieved. The environmental effects from replacing of the fuels are exposed. The obtained results can be used to predict the change of the temperature field in the anode furnace when changing the conditions of its operation.
