Sulphur emissions from a furnace plant are reduced by injecting into the hot flue gases a lime-rich powder having a particle size beneath k50 = 10 mu m. The powder used is obtained by finely-grinding lime-rich material in at least one stage in a mill which operates with agitated grinding medium. The fine-grinding process may be effected as a dry-grinding process essentially in immediate conjunction with the use of the powder, optionally in the presence of an NOx-reducing material. |
