摘要
An apparatus for calibrating a particulate matter continuous emission monitoring system includes: a feed unit that supplies particulate matter of a known mass flow rate; an eductor unit connected with the feed unit that receives particulate matter therefrom; a fluidizing unit connected to the eductor that supplies gas to the eductor unit, wherein the particulate matter and gas are combined into a fluidized mixture; and a probe connected to the eductor configured to extend within an industrial stack and deliver the fluidized mixture therein. Such an apparatus can provide accurate data regarding particulate matter concentration that can be compared with readings on the PM CEMS and enable a calibration curve to be generated. A tracer gas injection unit and analyzer may also be included.
