A method for reducing the sulfur emission of coal-fired power stations

摘要

In the equipment for desulphurisation and denoxation of the flue gas, the catalyst 13, which has been contaminated with residual quantities of sulphur during the denoxation, is removed, while fresh catalyst 12 is simultaneously fed into the denoxation equipment 11, from this equipment and passed into the power station boiler 1 and burnt therein together with the coal 2. Open-hearth coke from lignite is used as the fresh catalyst 12. IMAGE
