Pumpless metal atomization and combustion by means of negative pressure producing material and suitable flow control

The present invention relates to a method for combusting a electropositive metal with a combustion gas, the electropositive metal as a liquid or as a powder with particles having a particle size of less than 100 microns from a container by spraying a carrier gas into a in the flow direction of the carrier gas in cross-section first tapered first nozzle from the container into the first nozzle sucked is burned from this and sprayed with the fuel gas, and an apparatus for performing the method.
