Abstract

A method of operating a fuel-fired burner of an emission abatement assembly includes supplying a reduced amount of fuel to the fuel-fired burner in response to detection of a burner shutdown request. Such a reduced fuel supply continues for a predetermined time period after which fuel is no longer supplied to the burner. The supply of both combustion air and atomization air, along with spark generation, continues for a period of time after the fuel is shutoff. An emission abatement assembly is also disclosed.
