| Abstract: | For optimizing recirculation zone of the air distributed organ,CFD numerical simulation study on the flow fields and the recirculation zone distribution in the air distributed organ of oil-fired boilers are implemented using κ-ε model.The simulation result agrees well with the analytic results.It is showed that the size of the recirculation zone and the pressure loss decrease,while the angle degree of the inlet decreases;and the size of the recirculation zone and the pressure loss decrease,while the velocity of the inlet decreases;and the size of the recirculation zone increases,and the pressure loss decreases,while the temperature increases. |
| Keywords: | oil-fired boiler air distributed organ numerical simulation recirculation zone |
