| 摘要 |
The invention relates to a method of carrying out heat-consuming processes, wherein the total energy required averaged over a year for the heat-consuming process originates from at least two different energy sources, where one of the energy sources is an electric energy source whose power varies in the range from 0 to 100% of the total power required, and three different energy modes can individually provide the total power required for the heat-consuming process: (i) exclusively electric energy, (ii) a mixture of electric energy and at least one further nonelectric energy source or (iii) exclusively nonelectric energy, where the changeover time in which the change from one energy mode to another energy mode is completed is not more than 30 minutes. |

1. A method of carrying out a heat-consuming process, wherein a total energy required averaged over a year for the heat-consuming process originates from at least two different energy sources, where one of the energy sources is an electric energy source whose power varies in the range from 0 to 100% of the total power required, and where an excess power, which is defined as a power which is offered on a power market at well below generation costs or at prices which, based on the energy content, are lower than for a fossil fuel having the same joule value or for nothing or even at negative prices, is used without intermediate storage or prior smoothing/compensation in a power station in the heat-consuming process,
and wherein the following three different energy modes can individually provide the total power required for the heat-consumer process: (i) exclusively electric energy, (ii) a mixture of electric energy and a further nonelectric energy source or (iii) exclusively nonelectric energy, where a change of energy sources/energy modes is effected while carrying out the heat-consuming process and the changeover time in which the change from one energy mode to another energy mode is completed is not more than 30 minutes, where the nonelectric energy source is supplied by oxidative processes, and the thermal energy which is taken from the electric energy source with power which fluctuates over time, and which is for the heat-consuming process, is supplied by inductive or resistive methods, plasma processes, heating by electrically conductive heating elements/contact areas or by microwaves, the two or more energy sources being connected in series or in parallel. |
