Title

Study and Improvement of Recirculation Fan in Direct Reduced Iron (DRI) Plant Gas Heater

Abstract

The paper focuses on optimum operation of Recirculation Gas (RC)/Flue Gas Fan in Direct Reduced Iron Plant Process. Gas Heater is used to increase temperature of reduced gas from 50 Deg C to desire temperature upto 850-900 Deg C. Gas heater has four chambers namely, D01, D02, D03 and D04. D01 and D02 are the horizontal chambers, D04 is a vertical chamber. In D01 Combustion Chamber, Tail Gas is used as main fuel with Combustion air and LPG is burnt using Main Burner. Between D01 and D02 there is shield called Radiant Shield. The purpose of using radiant shield is to regulate the temperature of flue gas from D01 to D02. D02 chamber has 4 tube bundles installed in series inside which Pressure Swing Adsorption (PSA) Product/Reduced gas (enriched CO & H2) coming at 40°C from PSA unit will be made to pass. Flue gas from Gas chamber is cooled by Recirculation Fan and passed through radiant shield to regulate temperature from D01 to D02 chamber. Problem due to high vibration at Recirculation Fan Drive end bearing restricted the fan speed for optimum operation. To solve the problem the existing operation of Recirculation Fan (RF) was studied and used TQM tool (Brainstorming) to identified the problem and decision is taken to change Material of Construction (MOC) of the impeller and revised the Standard Operating Procedure (SOP) to improve the performance of the Recirculation Fan in Direct Reduction Iron (DRI) plant gas heater.
