ABSTRACT
Since air pollution control occupies a leading position in the market for environ mental technology, this chapter concentrates on the engineering and material concepts in flue gas desulphurisation in fossil-fuel-fired power stations. Starting from the developments in the USA and Japan from about 1975 the use of metal lic materials of construction to accomplish these air pollution control tasks is described, using Germany as an example. Measures to reduce the pollutants in question were given a legal basis in Germany in 1974 with the Pollution Control and Noise Abatement Act (BlmSchG). In the same year the Technical Instruc tions for Air Pollution Control (TA-Luft) was passed, from which the regulations for large combustion plants (GFAVO) were later derived [1]. On this basis, from 1983 to mid 1988 a power station capacity of 37,000 MW at 72 sites in West Germany with 165 flue gas desulphurisation scrubbing lines and a total through put of 135 million standard cubic metres of flue gas was desulphurised [2].
