§ Mr. Heathcoat-AmoryTo ask the Secretary of State for Energy what information he has as to what approximate tonnage of limestone will be required per annum by the flue gas desulphurisation equipment on a 2,000MW coal-fired power station.
§ Mr. Michael SpicerA 2,000MW coal-fired power station using the limestone-gypsum flue gas desulphurisation process would use about 300,000 tonnes per year when operating at high load factors. This is approximately 0.3 per cent. of total limestone production in this country.
