Title:
SLAG HEAT RECOVERING DEVICE, SLAG HEAT RECOVERING METHOD, AND HEAT GENERATING METHOD
Document Type and Number:
Japanese Patent JP2015178913
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a device for recovering heat as high-temperature water from high-temperature slag generated in refining metal.SOLUTION: A slag heat recovering device 250 is composed of a charging portion 22 for high-temperature slag 21, a water tank portion 23 for reserving water, a slag discharging portion 210, and a heat exchanging portion 25. The charging portion 22 is inclined, the discharging portion 210 has a screw conveyor 29, and the heat exchanging portion 25 is disposed at an upper part in the vertical direction, of the water tank portion 23. The high-temperature slag 21 has a temperature of 800°C or more, and its grain size is 2-8 mm. The charging portion 22 has an inclined face of an inclination angle of 20-55 degrees. The high-temperature slag 21 is charged into water along the inclined face, the slag 28 after cooling is discharged, and steam 24 generated in charging the slag 21 into the water is recovered and made to exchange heat with water 27C to obtain hot water 27.
