Book Description
Recent advances in small once-through Alloy 800 steam generators, improved materials technology, and application of small industrial gas turbine technology to steam turbine cogeneration offers the potential to make a step increase in steam temperature from around 1000°F, where industry has been for almost fifty years, to 1500°F. In small cogeneration systems, it is economically practical to introduce new technology and make a step change in temperature where it may not be possible (given the regulatory environment and economic risk) for a major change in steam temperature to be introduced in the hundreds of megawatt size of an electric utility. Increasing the peak steam temperature in a steam turbine cycle allows more work to be extracted or electrical power to be generated from a given quantity of heat input. Figure 1 plots steam efficiency as a function of superheat steam temperature and pressure for a turbine-back pressure of 166 psia. This figure clearly shows that increasing the steam conditions from the typical current practice of 900°F and 900 psia to 1500°F and 1500 psia will increase the steam cycle efficiency by 53%. The combination of higher cycle efficiency with an advanced high efficiency steam turbine design provides a substantial increase in turbine output power for a given steam flowrate. The output of this advanced high temperature steam turbine is approximately twice that of a current industrial practive turbine for the same turbine flowrate as seen in Figure 2.

Book Description
This book presents the most recent trends and concepts in power engineering, especially with regard to prosumer and civic energy generation. In so doing, it draws widely on his experience gained during the development of steam microturbines for use in small combined heat and power stations based on the organic Rankine cycle (CHP-ORC). Major issues concerning the dynamic properties of mechanical systems, in particular rotating systems, are discussed, and the results obtained when using unconventional bearing systems, presented. Modeling and analysis of radial-flow and axial-flow microturbines are addressed in detail, covering rotor analysis with different bearing systems, simulation modal analysis, and stress analysis. Furthermore, experimental studies of the dynamic properties of microturbine elements are extensively described. Interest in distributed generation and CHP-ORC is growing rapidly, and the potential market for such systems promises to be very large. This book will be of value for engineers and scientists involved in the design, modeling, operation, and diagnostics of various types of turbomachinery, especially steam microturbines.

Book Description
This design guide offers a thorough discussion of the theoretical as well as the practical aspects of a cogeneration system design. A brief discussion of the legal and regulatory aspects is followed by a detailed discussion of the prime movers (reciprocating engines, combustion turbines and steam turbines), heat recovery and electrical recovery equipment. There are two case studies (a hospital and an industrial application) to help illustrate the entire design process. ASHRAE Research Project 737.

Book Description
Cogeneration can now turn up to 90% of the fuel burned into usable energy – compared to just 52% of the fuel typically burned in a local power plant and in a separate existing hot water heating system. The fifth edition of this comprehensive reference provides a wealth of information to assist you in evaluating the feasibility and potential benefits of cogeneration for your facility. Covered are recent regulatory developments and their impact, system selection and sizing, permitting requirements, operation and maintenance, financing, technology basics, micro turbines, absorption chillers, distributed generation, and numerous case histories. This new edition is updated with new material and comes with access to a useful program that can help determine the economic value of applying cogeneration for your clients’ benefit.
