The Midwest Power PCFB demonstration projects: AHLSTROM PYROFLOW{reg_sign} first and second generation pressurized circulating fluidized bed (PCFB) technology

Conference ·
OSTI ID:10147756
Midwest Power, Dairyland Power Cooperative, Pyropower Corporation (a subsidiary of Ahlstrom Pyropower Inc.), and Black & Veatch, have embarked on the demonstration of Clean Coal Technology (CCT) at Midwest Power`s Des Moines Energy Center (DMEC), in Pleasant Hill, Iowa. The DMEC-1 PCFB Demonstration Project was selected by the US Department of Energy for the demonstration of the First Generation Pressurized Circulating Fluidized Bed (PCFB) Technology. During Round 5 of the CCT Program, Midwest Power submitted a proposal for a second unit, to be known as DMEC-2. If selected by the DOE, the DMEC-2 unit will demonstrate Ahlstrom Pyropower`s Second Generation (Advanced) PCFB technology which will incorporate a topping combustor fired on coal derived gas generated in a PCFB carbonizer, to raise the firing temperature of the gas turbine and the total net plant efficiency. The First Generation PCFB technology has the capability to achieve 40--42% efficiency, the Second Generation technology can obtain an efficiency in the range of 44--47% net. This paper will provide a comparison of the commercial versions of the First and Second Generation PCFB systems, and the plans for demonstrating these systems for repowering and new plant installations during the late 1990`s and into the next century. A discussion of the DMEC-1 and DMEC-2 projects and their key technical features will be provided together with a projection of the future markets for these advanced clean coal technologies.
