SLAG DISCHARGING DEVICE FOR MELTING FURNACE

Document Type and Number:

Japanese Patent JP2002005423

Kind Code:

A

Abstract:

To provide a slag discharging device for a melting furnace, which is capable of sufficiently cooling molten slag discharged out of the melting furnace and capable of obtaining stably the crystallized slag excellent in quality without affecting the fluctuation of a pressure in a casing to the inside of the furnace.

The sealed type slag discharging device is provided with a slag conveyor 5 equipped with a plurality of molds 4 for receiving the molten slag 3 in the casing 2 to introduce the molten slag 3, discharged out of an ash melting furnace 1, into the molds 4 and, thereafter, discharge the same out of the casing 2 while cooling during transferring. The casing 2 is provided with an air inlet port unit 21 for supplying cooling air 20 and an air outlet port unit 22 for discharging the cooling air 20 whereby the casing is constituted so that the cooling air 20 is circulated in the casing through the air inlet port unit 21 and the air outlet port unit 22.
