Abstract

This report presents the results of a feasibility study to evaluate the use of medium Btu synthesis gas, produced from high-sulfur coal, in an Integrated Gasification Combined Cycle (IGCC) power plant, as an alternative to a conventional pulverized coal plant with flue gas scrubbers presently planned for the Sears Island, Maine site of Central Maine Power Company. The process configuration is based on the oxygen-blown Texaco Coal Gasification Process and a General Electric Combined Cycle power plant. The plant design includes a 5000 ton per day oxygen plant, four 1200 tons per day gasification trains plus one spare to reduce risk, four gas turbine-generators with heat recovery steam generators, and a reheat steam turbine generator. Plant output at ISO (59/sup 0/F) conditions is 524 MW net. The report includes preliminary design and arrangement drawings, a detailed plant description, detailed cost information, performance data, schedules, and an extensive evaluation of technical, economic, and environmental results. The results of the study indicate that the IGCC power plant is still a rapidly evolving technology. Before Central Maine Power Company can commit to construction of such a plant, several issues raised in the study need to be addressed. These issues deal with refinements inmore »« less

The IGCC Plant does have less environmental impact than a comparably sized conventional coal plant, while using a high sulfur, high ash, less expensive coal. The life-of-plant levelized busbar cost for the IGCC Plant is estimated to be 5% lower than for the conventional coal-fired plant, although the initial capital cost is approximately 60% higher. Other cycle designs were identified which have the potential for improving plant economics.},

Coal gasification for Sears Island

Conference Cummings, R; Halporn, A; Hastings, P; ... - Proc. Am. Power Conf.; (United States)

This paper reports on the construction of an integrated gasification combined-cycle (IGCC) demonstration plant on Sears Island, Maine. The current state-of-the-art, the incentives to continue work on plants using a gasification process, and the necessary successive steps to go from the current state-of-the-art to a mature technology are discussed. A DOE-sponsored study was undertaken to evaluate the feasibility of licensing, designing, constructing, and operating a nominal 500-MW commercial-sized IGCC power plant using Eastern high-sulfur coal at Sears Island. The major systems of the IGCC plant configuration include coal receiving, handling and storage; the air separation plant; slurry preparation; the gasificationmore »« less
Toms Creek IGCC Demonstration Project

Conference Virr, M

The Toms Creek Integrated Gasification Combined Cycle (IGCC) Demonstration Project was selected by DOE in September 1991 to participate in Round Four of the Clean Coal Technology Demonstration Program. The project will demonstrate a simplified IGCC process consisting of an air-blown, fluidized-bed gasifier (Tampella U-Gas), a gas cooler/steam generator, and a hot gas cleanup system in combination with a gas turbine modified for use with a low-Btu content fuel and a conventional steam bottoming cycle. The demonstration plant will be located at the Toms Creek coal mine near Coeburn, Wise County, Virginia. Participants in the project are Tampella Power Corporationmore »« less

Status report on Central Main Power Company's DOE funded feasibility study of the Sears Island Integrated Gasification Combined Cycle Power Plant

Conference Cummings, R; Hastings, P - Proc., Intersoc. Energy Convers. Eng. Conf.; (United States)

A DOE funded study is underway to evaluate the technical and economic feasibility of an Integrated Gasification Combined-cycle (IGCC) power plant on the Sears Island site of the Central Maine Power Company. The study objectives also include development of a plan for constructing and operating the power plant. This paper gives a status report on the work effort at a point midway through the study.
