Current Situation of USC o o • 1100 F (593 C)/4300 psi (30MPa) single reheat plants are SOA. About dozen plants exist in Europe and in Japan. • The EU has an ambitious RD project aimed at o o 1300 F(700 C)/5400 psi (37.5MPa) steam condition. • Phase 1 - 6 yrs/21 million Euro/40 companies/10 countries has been completed. EU contributes 40%. • Phase 2 - 4 yrs/11.2 million Euro/EU 50% started in January 1, 2002. • Demo plant envisaged for 2007. Funding being sought. • National programs in Germany. 4 Copyright © 2003 Electric Power Research Institute, Inc. All rights reserved. Goals of the DOE/OCDO Project The GOALS include: • Identify advanced materials that achieve cost competitive, environmentally acceptable coal based electric power generation that includes the use of high sulfur coals; • Enable domestic boiler manufacturers to globally compete for the construction and installation of high efficiency coal fired po
