Increased efficiency and flexibility of large coal-fired power plants applied to 350-MW-class units

摘要

Power generation fired on carbon-based fuels places high priority not only on profitability, but also on responsible fuel handling and consumption. Efforts to reduce CO2 emissions undertaken in the past have focused on large, state-of-the-art steam power plants in the higher output classes. As a result, measures aimed at increasing efficiency and flexibility were developed for large units. The Organisation for Economic Co-operation and Development (OECD) recently addressed the environmental requirements as a precondition for export financing for the entire range of coal-fired power plants. Going forward, the good experiences gained from existing high-end ultra-super critical (USC) coal-fired power plants needs to be transferred to power plants of the 350-MW size. Innovative products are needed to serve this market segment in the most beneficial way for power plant owners. Siemens has modified its core components to address these new requirements while bringing added value to our customers. Siemens' steam turbines demonstrate how technology for (U)SC applications in larger units have been introduced in proven turbine designs for subcritical applications. For steam turbine generators, Siemens is leading the way with an innovative mix of proven components and technologies to reduce initial, operational and service costs and provide top performance with operational flexibility.
