An apparatus and method for the creation, placement and control of an area of electrical ionization within an internal combustion engine combustion chamber or a fuel burner for a furnace is disclosed. A furnace includes a fuel source, a fuel burner, a plasma nozzle and igniter assembly, and the associated housing and flue structures. The plasma nozzle and igniter assembly is arranged so that the fuel sprayed out from the nozzle into the combustion area passes through or in close proximity to the area of plasma ionization. A fuel burner equipped with this electrical ionization device has its fuel efficiency enhanced by the complete and immediate combustion of substantially all of the fuel that passes through the area of plasma ionization. Exhaust gas recirculation using this system is also disclosed.

What is claimed is: 1. A furnace comprising: a housing; an inlet flow tube connected to the housing; an outlet passage connected to the housing for removing exhaust gases from said housing; an air blower attached to the inlet flow tube; an ignition device including: at least three electrodes having electrode tips, said electrode tips define a polygonal area disposed in close proximity to a location where fuel is injected; and a high voltage generation circuit for receiving electrical energy and creates a high voltage output that is delivered to said at least three electrodes; and wherein said electrode tips are arranged so that when the high voltage output from said high voltage generation circuit is supplied to each said electrode, a plasma ionization zone is formed between said at least three electrode tips; and a fuel supply line having an outlet disposed in a center of said at least three electrodes, whereby fuel is supplied from the outlet of said fuel supply line to the polygonal area.
