Denmark's new Asnaes power plant: model for clean energy from coal
In 1972, some 93 percent of total Danish fuel consumption was represented by oil. Due to oil price increases and uncertain supply, and because of the Danish public's lack of acceptance of nuclear energy, all expansion in the electricity generating sector until 1990 will be via coal-fired units. Denmark is one of the pioneers in replacing oil with coal in large power stations and industrial plants. The change has come about more rapidly and more comprehensively than in other countries. At the end of the 1970s, two large oil-fired power plants with a combined capacity of 600 megawatts, corresponding to a consumption of more than 1,200,000 tons of coal per year, were converted. In 1980, another two units switched to coal. Power station consumption of coal was 8,000,000 tons in 1980. With little coal reserves of its own, Denmark must import virtually all of this coal. Coal consumed in Denmark is not allowed to have a sulphur content greater than 1.7 percent. The use of flue dust separators, such as electrostatic precipitators, is required for collecting fly ash. In coal-fired power plants, these precipitators give cleaning efficiencies of better than 99 percent and can thus satisfy the emission standards of most countries. Fly ash can be utilized in cement manufacturing, sand stabilization, and landscaping. The new Unit 5 at the Asnaes Power Station, at Sjaelland, represents the last word in pollution-free power plant coal combustion. Block 5 is one of the most modern units in the world. Its design is adapted to the landscape; excess heat is used for fish farming. It is a showcase for efficient coal-fired power plants.
