| 摘要 |
An energy efficient metal melter is disclosed, said melter having a portion of melting energy supplied to it by a combustion process for heating a melter charge to a temperature where the melter charge can no longer maintain its shape. A portion of melting energy is also supplied to that melter by an electrical process for adding remaining transformational and sensible heat. Preferably, the combustion process uses a hydrocarbon fuel energy source selected from a distillate compound, gas compound or both and the electrical energy comes from a source selected from an external power grid, a generator and combinations thereof. Related methods are also disclosed.
