Abstract
Abstract Abstract— The adequacy of a high-temperature, high-pressure gas cleanup system in protecting a large industrial gas turbine in a combined PFBC cycle can be evaluated by determining the dust and alkali loading into and out of the hot-gas cleanup unit. Sub-pilot plant experiments were performed at the New York University (NYU)-DOE PFBC facility to evaluate Ihe performance of the Granular Bed Filter (GBF) designed by Combustion Power Company, Inc., Menlo Park, California, in terms of its ability to capture dust and alkali. The inlet to and outlet of the GBF were isokinetically sampled for alkali and dust loadings. The particulate sampling system consisted of a total filter and a cascade impactor. The total filter collected the dust in a microfiber tube. In Ihe impactor, the particles collected are separated according to their size. Alkali emissions were measured using two techniques, namely. NYU total vapor condensation method and METC/INEL on-line alkali monitor. The results show that the dust and ...
