Abstract:
1. A method for increasing the temperature of a substance in a container, wherein the container is configured to hold a partly solidified substance and a melted substance and where at least one heat exchanger comprising guiding means is positioned in the container, said guiding means comprising a housing, said housing comprising a plurality of openings arranged in a pattern along the length of said housing and where pumping means is connected to said guiding means, said pumping means comprising a pump positioned external of the container, said method comprising the steps of: a) exchanging heat between the heat exchanger and the partly solidified substance stored in the container, b) displacing by pumping means and guiding means the heat exchanged melted liquid substance through the plurality of openings, thereby stirring the substance and circulating the melted liquid substance and increasing flow speed and increasing heat exchange between the heat exchanger and the substances, and further increasing heat exchange between the heat exchanged melted liquid substance and the remaining substance in the container.
