Abstract

PURPOSE: To effectively recover different waste heat simultaneously, by specifying the use of air for burning combustible waste.
CONSTITUTION: One portion of air 11 for burning combustible gas is supplied to cooling tanks 3, 4, in which metal 1 and slag 2 tapped and solidified from an electric furnace are each charged every time they are formed under high temperature conditions as much as possible, by means of a ventilator 12, which inlet damper 14 is opened and closed by means of an automatic combustion controller 13, heat exchanged with solid metal 1 and slag 2 accumulated in the cooling tanks 3, 4, joining mixed with air 11 for burning remaining combustible gas, which does not pass through the cooling tanks 3, 4, and introduced to a wind box 15 of a waste heat boiler 6. Thus, the heat recovery speed of the intermittent solid waste heat of the metal 1 and the slag 2 is levelled by air for combustion to continuous combustible gas, fixed boiler load is maintained and the generation of excessive heat loss is prevented.
