Pumpless Metal Atomization And Combustion Using Vacuum Generation And Suitable Material Flow Control
First Claim
1. A method for the combustion of an electropositive metal selected from the group consisting of alkali metals, alkaline earth metals, aluminum, zinc, and alloys or mixtures thereof with a combustion gas, the method comprising:
- providing the electropositive metal in a container in the form of a liquid or powder comprising particles with a particle size of less than 100 μ
m;
flowing a carrier gas through a first nozzle communicatively coupled to the container via a first passage that meets the first nozzle at a first location along a flow direction of the first nozzle, the first nozzle having a tapered nozzle portion having a tapered cross section and located at least partially upstream of the first location at which the first passage meets the first nozzle;
sucking the electropositive metal from the container and into the first nozzle via the first passage;
wherein the electropositive metal sucked into the first nozzle is atomized in the first nozzle and burned with the combustion gas.

Abstract
A method is provided for combustion of an electropositive metal using a combustion gas. The electropositive metal, in the form of a fluid or powder having particles with a particle size of less than 100 μm, is drawn out of a container by atomizing a carrier gas in a first nozzle, which tapers in relation to the cross-section in the flow direction of the carrier gas. The electropositive metal is drawn out of the container into the first nozzle, atomized out of said nozzle and combusted using the combustion gas.
