Steam power plants
Fossil fired steam power plants will remain a bridge to a sustainable future. They are the linking element to renewable energy sources, which in future will provide sustainable power and are already on the rise.
High power output with low emissions
Electricity suppliers worldwide are facing tremendous challenges. They must reliably meet an ever-increasing energy demand, flexibly respond to load changes at all times and keep grids stable, while at the same time supplying electricity at the lowest possible price. By 2030, about one-third of the world’s total power generation will come from renewable energy sources, but coal-fired power plants will still cover approximately the same percentage of the global energy demand. Today’s market perspective shows that for some more decades coal-fired power plants are predicted to remain a significant contributor to the future power supply mix in various countries to meet our energy demand. Steam 4.0 stands for a power supply with highest efficiency, lowest emissions. How do we achieve that?
Steam 4.0 - Lower emissions with supercritical steam
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. 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 demonstrates how technology for (U)SC applications in larger units is successfully introduced in to smaller turbines originally designed for subcritical applications.
Utility Steam Turbines – Proven Technology - Power Output From 90 to 1,900 MW
SST-5000 Utility Steam Turbine Package
The SST-5000 is capable for supercritical and ultra-supercritical steam power plants. Due to its higher pressure and temperature ratings, power plant efficiency increases more than 46 percent and overall performance is improved.
In steam power plants the SST-5000 consists of a combined highpressure / intermediate-pressure turbine, and one or two low-pressure turbines. It is installed as a low- or high-level arrangement. There are various exhaust configurations available to create an optimized plant layout: down-, single-sided, and double-sided. Various extractions (up to 9 stages) create an optimized plant layout with down-, single-sided or doubles sided exhaust.
SST-6000 Utility Steam Turbine Package
Siemens Steam Turbines of the SST-6000 series are widely operated in coal-fired steam power plants with a power output up to 1,200 MW and an efficiency up to more than 46 percent.
Products of the SST-6000 series consist of a high-pressure turbine, an intermediate-pressure (IP) turbine, and up to three low-pressure turbines for 50 and 60 Hz.
The SST-6000 is installed as a high-level arrangement with down exhaust. Various extractions (up to 10 stages) are possible for feed water preheating, process steam, and district heating. The installed capacity of SST-6000 all over the world is more than 100,000 MW.
SST-9000 utility steam turbine package
Leading technology for efficient, flexible and reliable power generation
The SST5-9000 is a highly reliable steam turbine for applications in the conventional islands of advanced pressurized water reactors, with a power output up to 1,900 MW.
The half-speed SST5-9000 features a double-flow saturated steam high-pressure (HP) turbine and up to three double-flow low-pressure (LP) turbines with shrunk-on disk rotors. Shrunk-on disk design features proven technology: no stress-corrosion cracking that will require replacement of the low-pressure rotors or disks during the design life-time.
