A SINTER MIX PREHEATING SYSTEM BY STEAM INJECTION TO INCREASE SINTER MACHINE PRODUCTIVITY

摘要

The present invention relates to a sinter mix preheating system in the intermediate bunker/surge hopper of sinter machine, located closer to the sinter machine to avoid heat loss of the sinter mix while traveling to the sinter machine to thereby reducing re-condensation of moisture in the lower part of the sinter bed. Advantageously, the sinter mix preheating system is introduced in the intermediate bunker by adopting steam injection. The system allows the steam for heating to be taken from the main steam header through pipe line and supplied to the bunker through a plurality of nozzles located at the back side of the intermediate bunker, selectively disposed in a number of rows across the width of bunker. The present sinter mix preheating system in the intermediate bunker of sinter machine is thus having prospects for wide scale use in sinter plants with economy for achieving higher pre heat sinter mix temperature and improved productivity consuming lesser steam.
