A sampling system has been designed and is under construction at Brookhaven National Laboratory that employs a probe appropriate for direct extracted sampling of erosive range particulate matter from a coal gasifier outlet or a high pressure fluidized bed combustor. The sampling train is scheduled to be tested at the Morgantown Energy Technology Center on their 42 inch coal gasifier unit. This sampling system consists of four modules: (1) a null balance extraction probe with injection through a porous lined tube to minimize wall loss, (2) a stem type virtual impactor to separate coarse from fine particles, (3) a filter tape collector, and (4) a Beta gauge total mass detector. The key design feature of this system is a stem type virtual impactor which separates at ambient gas stream conditions the coarse particles from the sampling stream so that at upon filtration no condensible vapors, find particles or reactive gases pass through the filter tape. This system should provide coarse particle mass flux data with a time resolution of thirty seconds or better. The probe attemps to maintain integrity of the sample and has high mass loading applications. The train is designed in module form so that it can be tailored to the particular needs of the process stream. The accuracy of the system and its components, including sampling, transport, and detection have to be determined. Accuratemeasurement of the aspiration velocity and setting of the isokinetic conditions appears to be a problem.
