COKE BED TYPE MELTING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a coke bed type melting equipment capable of controlling dioxins-suppressing combustion easily, preventing the deterioration of pre-furnace working environment and preventing innocuous gas from being exhausted to atmosphere. SOLUTION: A coke combustion part 2 melting a substance for environmental treatment 10 is provided, and a cinder notch 3 discharging the molten slag YS melted to flow down by the combustion of the coke and slag gas SG outside a furnace is provided. A generated gas combustion part 4 burning the generated gas from the substance for environmental treatment 10 is provided, and an exhaust gas-exhausting part 5 exhausting the exhaust gas burned and treated by the generated gas combustion part 4 outside the furnace is provided. A coke bed type melting furnace provided with a primary air supplying opening 6 supplying combustion air to the coke combustion part 2 and a secondary air supplying opening 7 supplying the combustion air to the generated gas combustion part 4 is provided with a secondary air supplying mechanism 8 sucking the atmospheric gas RG around the cinder notch together with the cinder gas SG to form combustion air and supplying it to the generated gas combustion part 4 through the secondary air supplying opening 7.
