METHOD AND APPARATUS FOR CLEANING ELECTRODES OF A FUEL-FIRED BURNER OF AN EMISSION ABATEMENT ASSEMBLY

摘要

A method and apparatus for operating a fuel-fired burner of an emission abatement assembly includes detecting a burner shutdown request, and adjusting an air-to-fuel ratio of an air/fuel mixture being supplied to the burner to a ratio greater than a stoichiometric ratio in response to the burner shutdown request. The method further includes advancing an adjusted air/fuel mixture to an electrode assembly of the burner for a predetermined amount of time in response to the burner shutdown request. The burner is shut down after the predetermined amount of time has elapsed.
