Abstract

In addition to a sulphur-containing fuel (4) and an oxygen-containing gas (5), a pulverous alkali metal or alkaline earth metal oxide or carbonate (6) (particularly calcium or magnesium) is fed into the furnace (1) in an amount in excess in proportion to the sulphur dioxide gas formed in the combustion chamber of the furnace, and water and/or steam (9) is sprayed separately into the calcium oxide-containing and/or magnesium oxide-containing flue gases (8) either in the furnace or after leaving the furnace. Alternatively, or in addition, the pulverous oxide (6') can be fed directly into the flue gases (8) leaving the furnace (1). <IMAGE>
