Abstract

Provided is a burner using electric discharge as an ignition source such as arc or plasma rotating with flow, and more particularly, to a DPF regenerating burner that improves ignition performance of the burner by having a metal ball on a conical electrode surface where electricity is discharged, inducing accurate electric discharge through a metal ball, and supplying a fuel-air mixture toward the metal ball. The DPF regeneration burner includes a fuel-air mixture supplying unit having an injecting unit be connected to a reaction unit to supply the fuel-air mixtureto the reaction unit; and a metal ball on a circumference of the electrodeto ignite the injected fuel-air mixture. The DPF regenerating burner generates electric discharge in an electrode surface where a metal ball is located. The ignition performance is improved by accurately supplying a fuel-air mixture at a location where the electric discharge is generated.

Description

technical field [0001] The present invention relates to a burner utilizing an electric discharge as an ignition source such as an electric arc or plasma rotating together with a gas flow, and more particularly to a burner for regenerating a Diesel Particulate Filter (DPF), which Diesel particulate filters trap harmful particulates (i.e. black smoke) and also improve the ignition performance of the burner by having metal balls on the surface of the conical electrode of the discharge and supplying the balls with a fuel-air mixture . Background technique [0002] Since diesel vehicles have better fuel efficiency and greater power than gasoline vehicles, diesel vehicles are widely used as heavy vehicles. However, unlike gasoline engines, diesel engines emit particulate emissions because fuel is injected directly into the engine combustion chamber during the compression stroke and the fuel is incompletely combusted due to insufficient mixing of fuel and air during the above proc...
