In this concluding part of the series, the author discusses some of the features of the proposed system that can increase efficiency, and the application of steam super heating and reheating techniques in large industrial units.

 

The SST-111 combines the robustness and adaptability of a single-stage geared steam turbine with the higher efficiency of a multi-stage steam turbine

     

The new HRSG developed by Alstom, Optimized for Cycling and Constructability (OCC), provides a cycling capability and has a design which requires reduced field construction labor. It features a horizontal gas path with suspended vertical tubes arranged in single rows. The HRSG is is a three-pressure reheat cycle that can be combined with an integral duct burner system and catalytic emissions controls.

Below are the extracts from a paper titled, ‘Considerations in Selection of the Appropriate Cycle Chemistry Program for Combined Cycle Power Plants’ by Colleen M. Layman, Bechtel Power Corporation, Frederick, MD USA, submitted at the Electric Power 2012 Conference Program.

  RenewablesCareers.com, the online jobs board for the green energy industry, has seen a significant rise in demand for roles within the sector too, with a 55% year on year rise in the number of visits to the site. In addition, the number of vacancies posted has more than doubled annually since the company’s launch in September 2010, highlighting an upsurge of interest for roles within the sector.

  Flowserve Corporation, a provider of flow control products and services for global infrastructure markets, has shipped the first of several main steam isolation valves (MSIVs) to the Sanmen Nuclear Power Plant, located in the Zhejiang Province of China. The MSIVs will be installed in Unit 1 of the plant, the first Westinghouse AP1000 nuclear power plant ever built. 

The United States is the leading of promoter of large-scale CCS projects.

Projections for natural gas generation growth are based mainly on the expectation of coal-fired power plant retirements, says a report titled, 'Gas and Electric Infrastructure Interdependency Analysis,' by the Midwest Independent Transmission System Operator (MISO). Taking advantage of the surplus of natural gas supply, LNG export facilities such as the nine U.S. export projects in operation or underway, offer the potential for a new baseload export market for natural gas. Canadian developers also have proposed several new export projects, the report says.
