Micro-combustor system for the production of electrical energy

A system for the production of electrical energy, comprising: a combustion chamber made of material that is able to withstand high temperatures, an injection device connected to said combustion chamber by means of an injection conduit, means for supplying combustion support substance into the combustion chamber and means for the removal of gaseous combustion products, means for the selective emission of radiation onto the outer surface of the combustion chamber. The combustion chamber is enclosed in a conversion chamber within which are maintained sub-atmospheric pressure conditions, so that a substantial part of the heat developed by the combustion reaction is converted into electromagnetic radiation.
