Abstract:
An ash-melting furnace, comprising:an ash supply port to supply ash provided at one end of said furnace;a slug discharge port to discharge molten slugs of the ash at another end of said furnace;an oxygen-enriched burner to melt the ash supplied from said ash supply port, the supplied ash being pushed forward along an inclined floor towards a drain port provided at a far end of said inclined floor to drain the molten slugs; a detector to detect or calculate a volume or a drain velocity of outflow of the molten slugs;a comparator for comparing an output value from said detector with a preset value; anda controller to control either quantity of the ash supplied or quantity of heat produced by said oxygen-enriched burner in response to a signal from said comparator in order to make the outflow of the molten slugs stable and continuous.
