The merger between the Power Generation divisions of ABB and Alsthom in 1999, has resulted in the present day Alstom Steam Turbine Retrofit Business being the only supplier who can offer both impulse (disc and diaphragm) and reaction (drum rotor) turbine retrofit solutions across the entire product power range. The impulse and reaction turbine technologies both possess design features that are aimed at achieving the best evaluated performance for retrofit turbine solutions. Alstom has now combined service proven features from these two technologies to form the new Compact Diaphragm steam turbine technology. This will allow turbine retrofit design solutions to be optimised to levels beyond that possible with either of the contributing technologies. The Compact Diaphragm design features are described in this paper, together with the validation of the new technology. The first application entered service in June 2007 in the retrofitted HP cylinder of a G3 HP turbine in USA and is also described in this paper.

Gas turbine is widely applied in power-generation field, especially combined gas-steam cycle. In this paper, the new scheme of steam turbine driving compressor is investigated aiming at the gas-steam combined cycle power plant. Under calculating the thermodynamic process, the new scheme is compared with the scheme of conventional gas-steam combined cycle, pointing its main merits and shortcomings. At the same time, two improved schemes of steam turbine driving compressor are discussed.

Sir Charles Parsons died some three years after the author was born. In this paper the author looks back at the pioneering work of Parsons in the field of power generation. It shows how he was able to increase output of the steam turbine generator from 7.5 kW in 1884 to 50000 kW in 1930 while increasing efficiency from 1.6 to 36 per cent, and relates these achievements to the current state of the art. Blading design, rotor construction and other aspects of turbine engineering are considered. The conclusion is that Parsons and his associates charted the course which manufacturers and utilities throughout the world have continued to follow, although increasingly sophisticated design and analytical methods have succeeded the intuitive approach of Parsons. His constant search for improved efficiency was and is highly relevant to today's concern for the environment. Finally, although it did not become a practical proposition in his lifetime, the paper reviews Parsons' vision of, and continuing interest in, the gas turbine, first mentioned in his 1884 patents.

In order to protect the environment, save energy and reduce emissions, and promote the utilization of wave energy, this paper reviews the development history of application generation technology, summarizes its development from two aspects of optimization and application of wave energy conversion devices, analyses the application examples of wave energy generation devices on ships. This paper summarizes the application trend of wave power generation devices on ships: wave power generation should be used as auxiliary and domestic electricity for ships and wave energy should be combined with other new energy sources. Wave energy application in marine power generation can effectively reduce emissions from ships, which is conducive to the sustainable development of human society. The system mainly included low speed marine main diesel engine, waste heat boiler, electricity generation sub-system of power turbine, electricity generation sub-system of steam turbine, the heat exchange equipment, electricity generation sub-system of organic working medium steam turbine and other equipments. Based on experimental data of main engine and later theoretical calculation, this paper studied the effect rules of electricity generation power, waste heat utilization potential and related parameters of the waste heat utilization system under different main diesel load and ambient temperature.

Photovoltaic Power

Solar energy is an inexhaustible and renewable energy without environmental pollution. Solar energy can be used in three kinds of forms: solar thermal energy, photochemical conversion and photovoltaic power generation. Among these, the final form of photovoltaic power generation is electricity which can be transported, applied and stored conveniently. On the basis of photovoltaic effect, solar cell is developed as a new technology to convert light energy into electrical energy using semiconductor. Up to now the two key problems of the development of solar cells are how to improve the conversion efficiency and reduce cost. Therefore, the material and production technology used for solar cells are discussed based on improving conversion efficiency in this article.
