Abstract

In particular saline brown coal with a high alkali content is burned with air in a fluidised bed (4). The resulting combustion gas is post-combusted and cooled in a cooled free space (7) above the fluidised bed (4). Via a recycling blower (15) and flue gas pipes (16), cold flue gas is blown into the fluidised bed (4) and the free space (7) in such a manner that, by virtue of the heat transfer to the cold flue gas and the cooling of the walls of the free space (7), a temperature of 780 degrees C maximum is maintained in the fluidised bed (4) and on the gas-side end of the free space (7), a wall temperature below the fusing temperature of the ash is maintained, and in the free space a post-combustion zone with a temperature of 850 degrees C maximum is maintained. <IMAGE>
