Investigation of High Velocity Wedge Separator for Particle Removal in Coal Gasification Plants. Phase I Report by PDF Summary

Book Description: This report summarizes the results of Phase I of the High Velocity Wedge Separator Program performed under Contract EF-77-C-01-2709. Phase I is concerned with the conceptual design and feasibility study of a high velocity wedge separator, which could potentially reduce equipment size and cost of hot temperature particulate removal equipment for coal-derived gases. Using the Foster Wheeler two stage entrained flow gasifier as reference case, a preliminary evaluation of the feasibility and practicality of the conceptual design is considered. For this purpose, preliminary fluid flow analysis is conducted, the particle collection efficiency defined and potential erosion problems identified. Recommendations are presented for verifying the analysis by conducting an analog model investigation. The preliminary design of the experimental device is summarized, defining collection efficiency, overall pressure drop and general application to coal gasification processes of interest. The theoretical results indicate that a properly designed high velocity wedge separator can have a high collection efficiency with acceptable pressure drops. The wedge separator can be designed for any particle distribution inputs as available from pilot testing. The ambient model lends itself to the accurate measurement of particle distribution and detailed fluid mechanic optimization.
