Title: Heat recovery apparatus from molten slag
Inventor: OKUNO RIYUUZOU
IPC: F27D15/02
Filed: 1979-01-10
Abstract: PURPOSE:To recover the heat energy possessed by molten slag with high efficiency by flowing the slag into a rotating trough and heat exchanging the same with the cooling medium passing in the heat transfer pipe in the upper part of the trough while stirring the slag with stirrers. CONSTITUTION:The molten slag of about 1500 deg.C which is discharged from blast furnaces or convertors is carried to the position of the charger 3 of the heat recovery apparatus by the pan wheel 2 running on rails 2. The pan 2a of the pan wheel 2 is turned to flow and charge the molten slag down into the loading part 5 of the rotary trough 4 of the heat recovery apparatus through spout 3a. The rotary trough 4 is annular within the horizontal plane and is rotated in the circumferential direction 7 by a drive unit 6. The molten slag radiates heat from its surface and heats the cooling medium in the heat transfer pipe provided in the upper part of the rotary trough. The heat energy is taken out as the hot water heated to high temperature or high temperature steam. At this time, the molten slag is stirred with stirrers 24 so that always high temperature portions expose toward the heat transfer pipe and as a whole the slag is evenly cooled to become granular solid slag. The solid slag is discharged to outside the rotary trough by a discharge unit 37.
