Alstom's Chemical Looping Coal-Fired Power Plant Development Program: Alstom Power

摘要

Alstom is a major, worldwide supplier of power plant equipment. Alstom is one of the very few companies, worldwide, that can supply a turnkey power plant which includes the entire boiler/scrubber island and combustion turbine or steam turbine power block of their own design and manufacture. Over 40% of the world's power plant steam generators are of Alstom design. Environmentally, Alstom has pioneered the development of power plant SO{sub}2 scrubbers, CO, NO{sub}x and particulate control and most recently mercury capture systems. Over the last decade, Alstom has launched a comprehensive CO{sub}2 Capture Technology development program involving the development of pre-combustion, oxy-firing and post-combustion CO{sub}2 capture processes for world-wide deployment on new and existing coal, oil and gas fired power plants. One of these technologies, currently known as chemical looping, has the potential to be the most efficient and most cost-effective means of capturing CO{sub}2 from coal-fired power plants, while at the same time providing extremely clean, low-cost and high-efficient operation. The development effort encompasses work being done within ALSTOM both in the US, under the sponsorship of the US Department of Energy, and in Europe, under European Union sponsorship. The first use envisioned for Alstom's chemical looping is in supercritical steam power plants. In this application, the technology can be employed in a green-field power plant application or it can be added to a pulverized coal boiler or circulating fluidized bed boiler sometime in the future whenever CO{sub}2 capture is required.
