摘要:

Work at United Glass has shown that relatively simple systems can be utilised to electrically heat the glass in the forehearths. This results in better and more consistent glass conditioning, and the important bonus feature has been significant energy savings which have resulted because of the electric heating

摘要:

The Central Electricity Generating Board is responsible for the generation and transmission of electricity in England and Wales. Currently the CEGB has 78 power stations with a net capacity of 52 GW, and about 77% of generation is from coal and about 16% from nuclear power. For the future, 900 MW coal-fired units are under development, and the first PWR is under construction. Wind power and other forms of generation will provide further diversity of energy sources

摘要:

The continuing management objective within the CEGB is to optimise availability, thermal efficiency and flexibility throughout the life of a power station, and in more recent years attention has also been given to the problems of plant-life extension. The improvement of the performance, particularly of the 500 MW and 660 MW coal-fired units, has continued over a period of years despite increased two-shifting and the effects of middle life. This drive to improve plant flexibility has raised new challenges to the operators

摘要:

A range of engineering and operating problems arising on coal-fired power stations are described together with selected research and development facilities and expertise which have been applied to improve efficiency and availability. Many of the developments and facilities which contribute to improved plant performance are available from the CEGB under contract or from manufacturers operating under licence

摘要:

The Dinorwig scheme, which is one of the UK's largest construction projects, was designed with minimum impact on the environment. The station consists of 6 × 300 MW generators with the turbines capable of both generating and pumping. In addition, the units have the facility of spinning at no load, giving rapid response times between zero and full load. The flexibility of the plant enables it to be cost effective, replacing high-cost oil or low-efficiency coal plant, particularly for short-run periods

摘要:

After the oil price shocks of the 1970s, renewable energy research and development received a very welcome cash injection. Alternative-energy schemes were seen in a new light, and for the first time for many years microhydro systems were considered as an alternative to the diesel-powered generator. Capital costs, technical and cultural difficulties remained major problems for Third World areas
