New York University (NYU), under a Department of Energy (DOE) contract, has designed and constructed a sub-pilot scale Pressurized Fluidized-Bed Combustor (PFBC) Facility at the Antonio Ferri Laboratories, Westbury, Long Island. The basic feature of this experimental research facility is a well-instrumented, 780 mm diameter coal combustor capable of operating up to 1010 kPa and provided with a liberal number of ports, making it a versatile unit for study of fundamental in-bed phenomena. Further, the overall design features make it a flexible facility for solving a variety of industrial research problems. The main objectives of the facility are three-fold: to develop fundamental data and correlations in the fluid mechanics and combustion process in PFBC; to perform research in important areas of pressurized fluidized bed-combustion, like low-grade fuel combustion under pressure; and to provide the PFBC community with an experimental research tool for basic and applied research in order to accelerate the commercialization of this technology. The facility started its shakedown tests utilizing bituminous coal in September, 1982. Subsequently, experimental research was, and is, being conducted in the combustion of North Dakota lignite at 710 k Pa. The results presented in this paper describe the research recently obtained with tests conducted at pressurized conditions (710 k Pa) utilizing North Dakota lignite. Preliminary results indicate that the agglomeration process may be suppressed due to the higher pressure. In addition, the research indicates than an inert bed material could be used in the combustion process for controlling SO/sub 2/ emissions. This is attributed to the alkali compounds present within the ash of the lignite. The research also indicates that SO/sub 2/ emissions could be controlled by varying the excess air.
