Investigating the Performance of CO Boiler Burners in the RFCC Unit with CFD Simulation

The combustion chamber's internal refractory in Imam Khomeini Oil Refinery Company (IKORC) was damaged several parts, requiring operating conditions and re-inspecting the design of chamber using CFD. Simplify 3D simulation, decrease number calculations, symmetry principle applied simulation. results, independent mesh network, were investigated via increasing nodes. one-stage, two-stage, multi-stage overall mechanisms, which designated, examined compared to actual measured data a calculation error less than 8% obtained. Ultimately, selecting simulation streams mixing length scrutinized, as result, current approved. temperature velocity flows investigated. In chamber, farther we are from burners, more uniform profiles also become wall increases. rate reaction evaluated with different points chamber. results showed that wall's is appropriate range has not suffered any thermal damage. Unlike wall, burner (at point) an unauthorized temperature; there possibility damage can be eliminated by changing currents. Unsuitable large amounts oxygen exhaust gas indicated steam boiler performance far optimal condition specific changes would required air streams. Streamline demonstrated primary stream effective for decreasing CO NOX outlet stream. secondary significant prevent coating reduce safety hazards.
