utility industry has recommended to be accomplished prior to commercialization. The program’s successes leave this last remaining activity (ComTest Phase 2) that the U.S.

It then obtained ASME code approval for their use in U.S. It subjected these materials to extensive laboratory and steam loop testing. It developed the welding and joining techniques along with manufacturing processes for casting and wrought products made from these new high-nickel alloys. The A-USC Consortium identified these needed materials during earlier phases of the program. The increase in a plant’s efficiency is limited unless new materials able to withstand these higher operating temperatures and pressures are identified and approved for use. fleet) to more than 45% higher more » heating value (HHV) (>49% lower heating value ).

These advanced cycles, with steam temperatures up to 1400☏ (760☌), can increase the efficiency of coal-fired boilers from an average of 35% (current U.S. The purpose of the consortium was to advance the state of the art for power generation by evaluating and developing materials that allow the use of advanced steam cycles in coal-based power plants. Department of Energy (DOE) and the Ohio Coal Development Office (OCDO) and cost shared by industrial and not-for-profit partners. Advanced Ultra-Supercritical (A-USC) Consortium was formed in 2001 as a government/industry program, sponsored by the U.S. Efforts were also undertaken to identify and evaluate other potential sites for high pressure testing. The first step of the ComTest, the steam turbine test, was determined best suited for a site in Youngstown, Ohio. The AUSC Component Test was premised on the program occurring at multiple facilities, with the operating temperatures, pressure and/or size of these components determining the optimum test location. The A-USC ComTest program would define materials performance requirements, plan for overall advanced system integration, design critical component tests, fabricate components for testing from advanced materials, and carry out the tests. Based upon the recommendations and outcome of a Consortia-sponsored workshop with the U.S.’s leading utilities, a Component Test (ComTest) Program for A-USC was proposed. DOE/OCDO A-USC Steam Boiler and Turbine Materials Consortia identified the key areas of the technology that need to be tested at a more » larger scale.

To decrease the identified risk barriers to full-scale implementation of these advanced materials, the U.S. However, as valuable as these material loops have been for obtaining information, their scale is significantly below that required to minimize the risk associated with a power company building a multi-billion dollar A-USC power plant. These materials or alloys have shown, in extensive laboratory tests and shop fabrication studies, to have excellent applicability for high-efficiency low CO 2 transformational power generation technologies previously mentioned. Successful research and development resulted in metallic alloy materials and fabrication processes suited for power generation applications with metal temperatures up to approximately 1472☏ (800☌). This testing included air- or steam-cooled “loops” that were inserted into existing utility boilers to gain exposure of these materials to realistic conditions of high temperature and corrosion due to the constituents in the coal. DOE)/Ohio Coal Development Office (OCDO) advanced ultra-supercritical (A-USC) Steam Boiler and Turbine Materials Consortia from 2001 through September 2015 was primarily focused on lab scale and pilot scale materials testing.
