Industrial Applications Containerized 7.8 MW Power Plant ConceptPresented at Power Gen Europe 2006, Cologne, GermanyThis paper discusses a new power plant concept by means of case studies for the main CHP applications. The CHP plant concept for 5-13 MW gas turbines reflects the requirements of this market segment. The first stage the development is based on the Siemens’ SGT-300 industrial gas turbine which is designed for highly efficient combined heat and power generation. The power plant systems are packaged into modular unit, which are pre-engineered and packaged into containers and interconnected on the construction site. The paper investigates improvements in economic value for the end user of such a plant, considering aspects such as construction and erection time, lifecycle cost and operational flexibility.

Gas turbine cogeneration activities – new Power Plants for Uralkali’s facilitiesPresented at Russian Power, 2006, Moscow, RussiaThis paper describes the supply of four SGT-400 Gas Turbine generating packages rated at 12.9MWe each, to Uralkali JSC of Russia for installation at two potassium mines in Berezniki City. The SGT-400 engines are the key components for two cogeneration plants which are located in one of the main industrial centers of the Ural region. Each cogeneration plant will comprise two generating sets in order to provide efficient and reliable production of power and steam for use in the mines and for the manufacturing process. The paper describes the advantages of the technology and the details of the specific application.

Moscow City, a state-of-the-art Combined Heat and Power PlantPresented at Russian Power, 2006, Moscow, RussiaCogeneration, or production of combined heat and power (CHP) is one of the most efficient and environmentally favorable methods of energy conversion in the power generation industry. This paper presents the technology of CHP plants and gives an example of an application in Russia, “Moscow City.” The plant consists of two combined cycle blocks, type SCC-800 2 x 1. Each block is based on two 45 MW SGT-800 gas turbines and one 30 MW SST-700 steam turbine. The paper describes the advantages of the technology and the details of the specific application

CHP plants for Cities and Industries – beneficial for economy and environmentPresented at China Power 2005, Beijing, ChinaChina faces a great challenge to secure the electricity supply for a steadily growing economy and at the same time use environmentally friendly technologies. The simultaneous production of electric power and heat (Combined Heat and Power = CHP) is the preferred solution in terms of economic and environmental efficiency. This paper shows how modern CHP technology using different fuel types and plant technologies can contribute to conserving fuel resources and minimizing carbon dioxide emissions.

Enhanced power and heat generation from biomass and municipal wastePresented at Power Gen Europe 2005, Milan, ItalyThe Municipal waste and biomass is mostly used only for steam or hot water production for district heating, but the increase in energy prices has made it more customary to produce electricity production by adding a steam turbine. By also adding a gas turbine to municipal waste or biomass- burning plants, the power and heat generation can be substantially increased, not only by the gas turbine power, but also by the improved steam cycle.

Industrial self-generation - a cross-commodity hedge in the EU emissions tradingPresented at Power Gen Europe 2005, Milan, ItalyThe EU Emissions Trading Scheme (EU ETS) bears various uncertainties and price risks for the commodities CO2, power and fuel. However, real life cases and the insight into market mechanisms show that industrial self generation is a valuable cross-commodity hedge against these risks. The EU Emissions Trading Scheme introduced CO2 as a new commodity. This paper demonstrates that, contrary to the common perception, this new commodity is leading to a reduced risk for CHP plants.

Design Specifics of High Efficiency Biomass Power Plants for fresh wood from forestry exemplified at the 23 MWe Biomass Power Plant Simmering / Vienna – AustriaPresented at Power Gen Europe 2005, Milan, ItalyThe utilisation of biomass within renewable energy production is the option with the biggest rate of growth in the coming years. However, as the resources of biomass available for producing energy are limited, maximum utilisation of the fuel is very important. Technologies chosen will be exemplified in this paper by two projects executed by Siemens Power Generation. One is a project in South Italy (Biomass Power Plant Monopoli) that has been in commercial operation since the beginning of 2004. The other one is a project in Vienna (Biomass Power Plant Simmering) that has been under project execution since the end of 2004.

TMF crack initiation lifing of austenitic carbide precipitating alloyspresented at ASME Turbo Expo 2004, Vienna, AustriaRecent work within DDIT has shown that Ni base superalloys like HAYNES230, Co base superalloys like HAYNES188, super stainless steels like HAYNES HR-120, and stainless steels like 253MA are similar from a materials modelling point of view. They are austenitic, delivered solutioned, and precipitate secondary carbides and other brittle phases in service and during cyclic tests at elevated temperature.

Experimental Investigation of Airflow and Spray Stability in an Air-Blast Injector of an Industrial Gas Turbinepresented at ASME Turbo Expo 2004, Vienna, AustriaThe airflow field and spray characteristics from an air blast type of injector in an industrial gas turbine (GT) combustor geometry have been investigated experimentally and numerically. The studied injector is a conventional liquid fuel injector used in the industrial gas turbine GT10B. The flame in the current combustor is stabilized by a highly swirling flow.

Biomasse Energy Utilization & Environment Protection - Commercial Reality and Outlook presented at Power-Gen Asia 2003Numerous biomasses fuelled power plants, as well as process steam and heat-producing plants are already in operation worldwide. However, the real environmental benefit of biomass utilization will come when we can use large amounts of biomass-based fuel to generate electricity, thereby considerably reducing consumption of fossil fuels.

Biomasse Combustion With State Of The Art Bubbling Bed Steam Generatorspresented at Power-Gen Europe 2003Biomass fuel exists in various forms, traditionally as wood, bark, harvesting residues and organic waste resulting from agricultural industry. In the new type of biomass the carbon content for incineration is contained in the so-called "renewable energy sources" - residual material and residues like industrial waste, tailings, sewage sludge and RDF. Our main combustion technology for these biomass fuels is the bubbling fluidised bed combustion named "EcoFluid" with our special design features.
