1. A heat generating arrangement for generating heat for use in a heat consumer, wherein the heat generating arrangement comprises:
a heating apparatus arranged to receive aluminium and superheated steam, wherein the heating apparatus is arranged to be heated by superheated steam having a heating arrangement temperature and arranged to melt the aluminium inside the heating apparatus to form liquid aluminium,
an atomizer arranged at an outer end of the heating apparatus arranged to atomize the liquid aluminium at the outer end of the apparatus by using superheated steam exiting the heating apparatus as the atomizer;
a reactor connected to the outer end of the heating apparatus in which the liquid atomized aluminium is arranged to react with the superheated steam exiting the heating apparatus to produce aluminium oxide, hydrogen and heat, thereby increasing the temperature of the superheated steam that is not consumed by the reaction with the liquid atomized aluminium in the reactor to a reactor temperature;
a combustion chamber connected to the reactor and to the heating apparatus arranged to receive superheated steam having the reactor temperature and hydrogen, wherein oxygen or air is provided to the combustion chamber from an external oxygen source, an external air supply or from the atmosphere, wherein the heat consumer is arranged in direct connection to the combustion chamber, where:
either the hydrogen is spontaneously combusted inside the combustion chamber to increase the temperature of the superheated steam to a heat consumer temperature, where the superheated steam having the heat consumer temperature exchanges heat with a heat exchange medium within the heat consumer, lowering the temperature of the superheated steam to the heating arrangement temperature,
or the hydrogen is spontaneously combusted inside the combustion chamber to provide high temperature exhausts to the heat consumer and where superheated steam is continuously added to the heat generating arrangement,
wherein a bypass connection is arranged between the reactor and the heating apparatus, allowing superheated steam to bypass the combustion chamber.
