20150353406 | ENERGY RECOVERY FROM FUMES FROM A MELTING FURNACE USING A GAS TURBINE AND HEAT EXCHANGERS - The invention relates to a unit and method for melting in a furnace comprising a combustion-heated melting chamber, in which the air is heated by means of heat exchange with the fumes generated by combustion. The heated air is used in a gas turbine in order to generate electrical and/or mechanical energy. In addition, the effluent from the gas turbine is used to pre-heat the combustion oxygen and/or gaseous fuel upstream of the melting chamber. | 12-10-2015 |
