Abstract
Disclosed is a device for firing waste sludge in a coal-gasifying process by means of two separate dust fireboxes connected respectively to a fume gas drier and to a heat energy generator in the form of a steam boiler. To prevent caking of the ashes, fume gases in the second firebox are cooled down by the admixture of waste gases fed back from the heat energy generator. In this manner, the amount of the exhausted waste gas is reduced and steam production is increased.
