Title: Use of a polishing scrubber with a fluid bed boiler

Abstract

Once viewed as {open_quotes}competitive{close_quotes} technologies, the circulating dry scrubber (CDS){reg_sign} and circulating fluid bed (CFB) boiler are being used together to achieve enhanced performance with lower overall costs. The need to understand the synergy between these two technologies is driven by deregulation of the power industry and the 1990 Clean Air Act Amendments. Deregulation of power production in the US has spurred the growth of Independent Power Producers (IPP) who are responding to Industry`s demand for lower cost fuels, and close attention to annual operating costs. Utilities have to provide {open_quotes}open{close_quotes} access to their transmission lines allowing various IPP`s to connect with the end user. Industrial users can now choose from one of several sources of electricity with prices per kilowatt hour that are much lower than what they are currently being charged. The race is on to reduce power production costs and fuel can be the key in many cases. IPP`s and industry are banding together in very logical ways that can benefit both. Industry`s byproducts with heating value can be sold {open_quotes}over the fence{close_quotes} to an IPP who provides the industry with low cost steam and or electricity in return. However, many alternative lower cost fuels also havemore » a higher emissions potential for criteria pollutants such a SO{sub 2}, NO{sub X}, particulate, or other emissions such as VOC`s and mercury which are more recently receiving attention. Cost effective management of these environmental issues must be an integral part of the project planning process. Three such cases are examined that involve the use of CFB`s with the CDS{reg_sign} as a polishing scrubber for SO{sub 2}. The first two cases involve repowering of existing facilities with petroleum coke as the fuel. The last case involves a new facility powered with low sulfur coal.« less
