Description:
The report gives the status of the most promising high-temperature/high-pressure (HTP) particulate control devices being developed. Data are presented and anticipated performance and development problems are discussed. HTP particulate control offers efficiency and potential economic advantages over cold gas cleanup in pressurized fluidized-bed combustion (PFBC) and low-Btu coal gasification (LBCG) combined-cycle power generation systems. However, considerably more development will be necessary in order to demonstrate the technical and economic feasibility of HTP gas cleanup commercially. The alternative of recuperative heat exchange coupled with low-temperature/high-pressure particulate control is reviewed with regard to power system efficiencies or PFBC and LBCG combined-cycle processes. Successful hot gas cleanup has clear efficiency advantages (1-7%) over cold gas cleanup. The economics of hot gas cleanup, however, are very speculative at the current state of development.
