Patent ID: 8597021

Claim:
A fuel burner for producing heat through a combustion of fuel and air, said fuel burner comprising: a fuel burner housing having an air inlet and a flame outlet for directing heat resulting from the combustion of fuel and air; a fuel supply line having a fuel nozzle as an outlet; an ignition device comprising: at least three electrodes, each electrode having an electrode tip, said electrode tips define a polygonal area disposed in close proximity to a location where fuel is introduced, said fuel nozzle being disposed in close proximity to and separate from said at least three electrodes; and a plurality of high voltage generation circuits, each of said plurality of said high voltage generation circuits being a separate high voltage power supply and being connected to a separate one of said at least three electrodes with its respective electrode tip for receiving electrical energy to create a high voltage output that is delivered to at least one of said at least three electrodes; and wherein said electrode tips are arranged so that when the high voltage output from said high voltage generation circuits is supplied to each said electrode, a plasma ionization zone is formed at least in the polygonal area between said at least three electrode tips in order to cause combustion between fuel and air near said flame outlet.
