Title: Sintering plant
Inventor: ZUGUDA DOSHIO
IPC: F27D17/00
Filed: 1980-01-17
Granted: 1984-09-01
Abstract: In a sintering plant, quicklime is fed to the lower layer of raw materials on the sintering conveyor and only the downstream half of the windbox array(9) is connected to desulphurization equipment(14).  A heat exchanger(20) is disposed in the duct(11') forming the connection for preheating the water that is fed to a steam-producing boiler(22), which is operatively associated with the cooler(2) used for cooling the finished sinter.
